整合于金属壳体的天线结构Antenna structure integrated in metal housing

技术领域technical field

本实用新型涉及一种整合于金属壳体的天线结构，特别涉及一种将电子装置的金属外壳体做为天线辐射体的整合于金属壳体的天线结构。The utility model relates to an antenna structure integrated in a metal shell, in particular to an antenna structure integrated in the metal shell which uses the metal outer shell of an electronic device as an antenna radiator.

背景技术Background technique

由于无线通讯技术的发展，电子产品对于信号的接收质量要求越来越重视，例如全球定位系统(GPS)导航功能或是移动通讯能力等等。再者，电子产业对于电子产品要求轻、薄、短、小等特性之下，加上高度整合的芯片特性以达到小型化的目的。Due to the development of wireless communication technology, electronic products place more and more emphasis on signal reception quality, such as global positioning system (GPS) navigation function or mobile communication capability and so on. Furthermore, the electronics industry requires the characteristics of light, thin, short, and small electronic products, plus highly integrated chip features to achieve the purpose of miniaturization.

目前市面上的电子产品会以金属外壳包覆电路板及天线结构，该金属外壳具有强度高、不易损坏、具有金属质感的优点，但使用上述的金属外壳，由于金属外壳遮蔽的原因，会导致天线结构的效率不佳；例如在全金属外壳的产品中，为了保持天线的特性，上述全金属外壳必须结合非金属材质，以避免将金属件直接覆盖于天线结构上；又如在塑料上以电镀、化学镀工艺披覆金属层，以制作金属质感的外壳时，必须使用金属含量较低的镀液组成，以避免影响到天线的特性。At present, the electronic products on the market will cover the circuit board and the antenna structure with a metal casing. The metal casing has the advantages of high strength, not easy to damage, and a metal texture. However, the use of the above-mentioned metal casing will cause The efficiency of the antenna structure is not good; for example, in a product with an all-metal casing, in order to maintain the characteristics of the antenna, the above-mentioned all-metal casing must be combined with non-metallic materials to avoid directly covering the metal parts on the antenna structure; When electroplating and electroless plating processes coat the metal layer to make a metallic shell, a plating solution with a low metal content must be used to avoid affecting the characteristics of the antenna.

因此，为了解决金属外壳与天线的特性不兼容的问题，通常必须使用复杂、高成本的组装方法，以避免两者在特性上的干涉问题，故间接导致产品的成本上升。Therefore, in order to solve the problem of incompatibility between the characteristics of the metal case and the antenna, a complex and high-cost assembly method must be used to avoid the interference between the characteristics of the two, which indirectly leads to an increase in the cost of the product.

再一方面，随着电子产品的微小化，使得可用以调配的空间不足，导致上述金属外壳与天线的组装、排列的干涉问题更显严重。On the other hand, with the miniaturization of electronic products, the space available for deployment is insufficient, which leads to more serious interference problems in the assembly and arrangement of the metal casing and the antenna.

综上所述，本实用新型具有下列诸项优点：In summary, the utility model has the following advantages:

1、本实用新型可将天线整合于金属外壳，故金属外壳可成为天线的辐射体，故可利用金属外壳的面积提高天线的特性。因此，当产品的尺寸缩小化的同时，天线可利用金属外壳传输信号，即可有效解决产品空间导致天线本体过小的问题。1. The utility model can integrate the antenna into the metal shell, so the metal shell can become the radiator of the antenna, so the area of the metal shell can be used to improve the characteristics of the antenna. Therefore, when the size of the product is reduced, the antenna can use the metal casing to transmit signals, which can effectively solve the problem that the product space causes the antenna body to be too small.

2、本实用新型将天线整合于金属外壳，故在天线位置的考虑下，可解决金属外壳对传统天线产生干扰的问题；换言之，在产品组装上，即可不必考虑天线与金属外壳的干涉问题。2. The utility model integrates the antenna into the metal casing, so considering the position of the antenna, it can solve the problem that the metal casing interferes with the traditional antenna; in other words, in product assembly, it is unnecessary to consider the interference between the antenna and the metal casing .

当然，本实用新型还可有其它多种实施例，在不背离本实用新型精神及其实质的情况下，熟悉本领域的技术人员当可根据本实用新型作出各种相应的改变和变形，但这些相应的改变和变形都应属于本实用新型所附的权利要求的保护范围。Of course, the utility model can also have other various embodiments, and those skilled in the art can make various corresponding changes and deformations according to the utility model without departing from the spirit and essence of the utility model, but These corresponding changes and deformations should all belong to the protection scope of the appended claims of the present utility model.
