可以导电的天线结构Conductive Antenna Structure

技术领域technical field

本实用新型有关一种天线结构，特别是指一种以聚酯材料(PET)所制成基材运用在无线射频(RF)天线的可以导电的天线结构。The utility model relates to an antenna structure, in particular to a conductive antenna structure used in a radio frequency (RF) antenna as a base material made of polyester material (PET).

背景技术Background technique

无线射频辨识系统Radio Frequency Identification(RFID)此为利用无线电波来传送识别资料的系统，应用非常广泛，具有下列优点：Radio Frequency Identification (RFID) is a system that uses radio waves to transmit identification data. It is widely used and has the following advantages:

1.资料可以更新：条形码印刷的后就无法更改，RFID TAG则可以不限制次数地新增、修改、删除RFID TAG内储存的资料。1. The data can be updated: after the barcode is printed, it cannot be changed, while the RFID TAG can add, modify, and delete the data stored in the RFID TAG unlimited times.

2.方便资料辨读：条形码阅读器需在近距离而且没有物体阻挡下，使扫描光源照射在条形码上才能辨读。RFID TAG只要在无线电波的范围内，即可以传递信号。2. Convenient data reading: the barcode reader needs to be at a close distance and not blocked by objects, so that the scanning light source is irradiated on the barcode to be able to read. RFID TAG can transmit signals as long as it is within the range of radio waves.

3.储存资料的容量大：一维条形码的容量是50Bytes；二维条形码最大的容量可以储存2至3000字符；RFID TAG最大的容量可以达数Megabytes。3. The capacity of storing data is large: the capacity of one-dimensional barcode is 50 Bytes; the maximum capacity of two-dimensional barcode can store 2 to 3000 characters; the maximum capacity of RFID TAG can reach several Megabytes.

4.可以重复性使用：条形码常随着商品的寿命结束而结束；RFID TAG因为本身资料可以更新，因此可以重复不断地使用。4. Can be used repeatedly: barcodes often end with the end of the life of the product; RFID TAG can be used repeatedly because its data can be updated.

5.可以同时读取数个资料：条形码阅读器一次只能读取单一条形码资料；RFID TAG的辨识器可以同时间辨识读取数个RFID TAG。5. Can read several data at the same time: the barcode reader can only read a single barcode data at a time; the RFID TAG recognizer can read several RFID TAG at the same time.

6.安全性：RFID TAG读取方面皆有密码保护，高度安全性的保护措施不易被伪造及变造。6. Security: RFID TAG reading is protected by passwords, and the highly secure protection measures are not easy to be forged and altered.

因此全世界最大的零售业龙头沃尔玛(Wal-Mart)从2005年1月1日开始，正式激活无线辨识系统(RFID)先导型试验；美国国防部、Metro(德国最大连锁超市)、Best buy(美国电子产品零售巨擘)，也纷纷要求旗下供货商导入或进行RFID相关试验，也预估到2008年RFID可以达30亿美元以上规模，到2006年将会使用价值22亿美元以上的卷标。Therefore, Wal-Mart, the world's largest retail leader, officially activated the pilot test of the wireless identification system (RFID) on January 1, 2005; the U.S. Department of Defense, Metro (the largest supermarket chain in Germany), Best buy ( U.S. electronics product retail giant) has also asked its suppliers to introduce or conduct RFID-related experiments. It is also estimated that by 2008, RFID will reach a scale of more than 3 billion U.S. dollars, and by 2006, it will use tags worth more than 2.2 billion U.S. dollars. .

而现阶段无线辨识系统(RFID)所面临到的瓶颈，其中一项即是卷标价格居高不下，请参阅图1所示，为常用软性铜箔基板(FCCL)结构侧视示意图。常用软性铜箔基板以聚醯亚胺Polyimide(PI)11为基材，二侧面分别涂布有接着剂(Adhesive)12后，各贴上一层铜箔13，再以蚀刻方式制作传统高成本的软性铜箔基板(FCCL)，将铜箔13蚀刻形成可以导电的天线形状结构。而上述制作方式由在原料成本偏高加上制程手续繁杂使得单位成本偏高，且不适在快速大量生产；另外所产生的废水也会对环境造成很大危害，而处理废水也会花费相当大的成本。因而制程成本、产能效率及弹性往往无法兼顾，在降低卷标成本以拓展市场接受度的议题主导下，取代传统原料及制程成本昂贵的蚀刻铜箔基版所发展的印刷真空电镀水洗天线技术，能大幅降低成本且符合市场需求与趋势，这将是取得竞争优势的方法。并且希望以制作卷标天线的技术能更延伸至其它相关产业应用。One of the bottlenecks that RFID systems are facing at this stage is the high price of labels. Please refer to Figure 1, which is a schematic side view of the structure of a commonly used flexible copper clad substrate (FCCL). Commonly used flexible copper foil substrates use polyimide (PI) 11 as the base material, and after the two sides are coated with adhesive (Adhesive) 12, a layer ofcopper foil 13 is pasted on each, and then the traditional high Low-cost flexible copper clad substrate (FCCL), thecopper foil 13 is etched to form an antenna-shaped structure that can conduct electricity. However, the above-mentioned production method has a high unit cost due to the high cost of raw materials and complicated manufacturing procedures, and is not suitable for rapid mass production; in addition, the waste water produced will also cause great harm to the environment, and the treatment of waste water will also cost a lot. the cost of. Therefore, the process cost, production efficiency and flexibility are often unable to be balanced. Under the leadership of the issue of reducing the cost of the label to expand market acceptance, the printed vacuum plating and water-washing antenna technology developed to replace the traditional etched copper foil base plate with expensive raw materials and process costs, Being able to significantly reduce costs and comply with market needs and trends will be the way to gain a competitive advantage. And it is hoped that the technology of making tag antennas can be extended to other related industrial applications.

请参阅图3A至图3D所示，为本实用新型可以导电的天线制造方法较佳实施例侧视结构流程示意图。如图3A，本实用新型可以导电天线的制造方法，首先提供一塑料膜基材2，前述塑料膜基材2为聚酯材料Polyethylene Terephthalate(PET)所制成，由对苯二甲酸和乙二醇化合后产生的聚合物。由在前述PET塑料具有以下特性，因此选用作为底材：1.耐用性及透明度高：耐热性及绝缘性良好，同时具有高透明度。2.利在环保：PET为环保塑料材质，取代安全性上堪虑的PVC(聚氯乙烯)塑料。3.可以回收再利用：PET塑料可以回收加工制成人造纤维，或二次加工的塑料制品，是塑料中最具再生价值的。4.质轻、耐冲击、不易碎裂。Please refer to FIG. 3A to FIG. 3D , which are schematic flow diagrams of the side view structure of a preferred embodiment of the manufacturing method of the conductive antenna of the present invention. As shown in Fig. 3A, the utility model can manufacture the conductive antenna, at first providing a plasticfilm base material 2, the aforementioned plasticfilm base material 2 is made of polyester material Polyethylene Terephthalate (PET), is made of terephthalic acid and ethylene glycol Polymers produced by the combination of alcohols.

而前述塑料膜基材2具有一第二厚度t，前述第二厚度t约在6微米至188微米(6μm至188μm)间。本实用新型较佳者，会再设计出一电路进行凹版制版作业，而常用凹版制版作业，方法分为三种：1.雕刻制版，版胴深度30μm至80μm(版胴镀铜→研磨→雕刻→镀铬→研磨)。2.腐蚀制版，版胴深度15μm至80μm(版胴镀铜→涂布→曝光→腐蚀→水洗→镀铬→研磨)。3.激光制版，版胴深度15μm至80μm(版胴镀铜→涂布→雷射→腐蚀→水洗→镀铬→研磨)。The aforementionedplastic film substrate 2 has a second thickness t, and the aforementioned second thickness t is approximately between 6 μm and 188 μm (6 μm to 188 μm). The better one of the utility model can design a circuit to carry out the gravure plate-making operation, and the common gravure plate-making operation, the method is divided into three kinds: 1. Engraving plate-making, the depth of the plate body is 30 μm to 80 μm (copper plating on the plate body → grinding → engraving → chrome plating → grinding). 2. Corrosion plate making, the depth of the plate body is 15 μm to 80 μm (copper plating → coating → exposure → corrosion → washing → chrome plating → grinding). 3. Laser plate making, the depth of the plate body is 15 μm to 80 μm (copper plating → coating → laser → corrosion → washing → chrome plating → grinding).

接着如图3B，将前述塑料膜基材2进行水洗涂料3印刷出设计出的电路，而使水洗涂料3具有预定的一天线图案21，因此会使前述天线图案21的位置呈现为镂空状态，前述水洗涂料3的厚度约略在1微米至3微米(1μm至3μm)间。当然为增加水洗涂料3位在前述塑料膜基材2上的接着强度，本实用新型在印制水洗涂料3前，可以先将一基材前处理剂(Primer)涂布在前述塑料膜基材2上，因此可以同时增强以下制程中一导电层4接着在前述塑料膜基材2上的接着强度，由此当然前述基材前处理剂(Primer)亦可以是印刷水洗涂料3后，再加以涂布在前述天线图案21及水洗涂料3上。由在前述水洗涂料3具有液分，因此需将前述塑料膜基材2进行干燥，加以去除水洗涂料3及前述塑料膜基材2的溶剂液分，且会使前述塑料膜基材2形成收卷。Next, as shown in FIG. 3B , the above-mentioned plasticfilm base material 2 is subjected to water-washing paint 3 to print out a designed circuit, so that the water-washing paint 3 has a predeterminedantenna pattern 21, so the position of theaforementioned antenna pattern 21 will appear as a hollow state, The thickness of thewash paint 3 is roughly between 1 micron and 3 microns (1 μm to 3 μm). Of course, in order to increase the bonding strength of the water-washing paint 3 on the aforementionedplastic film substrate 2, before the utility model prints the water-washing paint 3, a substrate pretreatment agent (Primer) can be coated on the aforementionedplastic film substrate 2, so it is possible to simultaneously enhance the bonding strength of aconductive layer 4 on the aforementioned plasticfilm base material 2 in the following process, so of course the aforementioned base material pretreatment agent (Primer) can also be printed after thewashing paint 3, and then add It is coated on theaforementioned antenna pattern 21 and thewashing paint 3 . Since there is a liquid in thewash paint 3, theplastic film substrate 2 needs to be dried to remove thewash paint 3 and the solvent liquid of theplastic film substrate 2, and theplastic film substrate 2 will form a roll.

再如图3C，将前述塑料膜基材2进行蒸着电镀，使前述天线图案21及水洗涂料3上设有一导电层4，前述导电层4为铜材质或铝材质所制成。本实用新型较佳实施例中，欲进行上前述导电层4前，先将前述塑料膜基材2进行电晕处理(Corona)，使前述天线图案21及水洗涂料3表面产生极化。所谓电晕处理是一种“电击”处理，它造成被印体的表面具有更高的附着性。电晕处理的产生是利用高电压高周波，分别为接地与诱电空气喷嘴产生电击，它们间没有电流通过，直至电压高达3000至5000伏特/平方厘米。再者，电击分子从空气喷嘴喷出，带着高能量的游离电子加速冲向正极，电晕处理就是由这密集且高能量喷出离子所产生的作用。这些离子以电击和渗透进入被印体的表面破坏其分子结构，进而将被处理的表面分子氧化和极化，以离子电击侵蚀表面，增加被印体表面的附着能力。As shown in FIG. 3C , the above-mentionedplastic film substrate 2 is evaporated and electroplated, so that the above-mentionedantenna pattern 21 and thewashing paint 3 are provided with aconductive layer 4, and the above-mentionedconductive layer 4 is made of copper or aluminum. In a preferred embodiment of the present invention, before theconductive layer 4 is applied, theplastic film substrate 2 is subjected to corona treatment (Corona), so that the surface of theantenna pattern 21 and thewashing paint 3 are polarized. The so-called corona treatment is a kind of "electric shock" treatment, which causes the surface of the printed body to have higher adhesion. The generation of corona treatment is to use high voltage and high frequency to generate electric shocks for grounding and induction air nozzles respectively, and there is no current passing between them until the voltage is as high as 3000 to 5000 volts/square centimeter. Furthermore, the electroshocked molecules are ejected from the air nozzle, and the high-energy free electrons are accelerated towards the positive electrode. The corona treatment is the effect of this dense and high-energy ejection of ions. These ions enter the surface of the printed object by electric shock and penetration to destroy its molecular structure, and then oxidize and polarize the treated surface molecules, erode the surface with ion electric shock, and increase the adhesion ability of the printed object surface.

最后如图3D，将前述塑料膜基材2进行水洗，使水洗涂料3与前述塑料膜基材2相分离，且前述导电层4位在前述天线图案21上形成具有预定的一第一厚度t1的导电天线，其中较佳者，前述第一厚度t1在0.1微米(0.1μm)以上。本实用新型较佳实施例中，再将完成的前述塑料膜基材2进行干燥，以去除导电层4及前述塑料膜基材的溶剂液分，且前述塑料膜基材形成收卷。Finally, as shown in Figure 3D, the aforementioned plasticfilm base material 2 is washed with water, so that thewashing paint 3 is separated from the aforementioned plasticfilm base material 2, and the aforementionedconductive layer 4 is formed on theaforementioned antenna pattern 21 with a predetermined first thickness t1 The conductive antenna, wherein preferably, the aforementioned first thickness t1 is above 0.1 micrometer (0.1 μm). In a preferred embodiment of the present invention, the completed aforementioned plasticfilm base material 2 is dried to remove theconductive layer 4 and the solvent liquid of the aforementioned plastic film base material, and the aforementioned plastic film base material is formed into a roll.

以上所述利用较佳实施例详细说明本实用新型，而非限制本实用新型的范围。凡是熟知此类技术人士皆能明了，适当而作些微的改变及调整，仍将不失本实用新型的要义所在，亦不脱离本实用新型的精神和范围。综上所述，本实用新型实施的具体性，诚已符合专利法中所规定的实用新型专利条件，故依法申请专利。The above description uses preferred embodiments to describe the utility model in detail, but not to limit the scope of the utility model. All those who are familiar with this type of technology can understand that appropriate and slight changes and adjustments will not lose the gist of the present utility model, nor depart from the spirit and scope of the present utility model. In summary, the specificity of the implementation of this utility model has met the requirements for a utility model patent stipulated in the Patent Law, so a patent application is required according to law.
