統’為GSM系統。GSM (GlobalSystem for Mobile Communications)泛歐數位式行動通訊系統，常被稱為第 二代的數位式行動電話。在GSM短短數年的發展中， GSM900MHZ成為全球數位網的主導標準，全球絕大部分的 GSM營運商都選擇了 90 0MHz的頻段。隨著GSM900頻率資源 曰益匱乏，已成為手機網路發展的瓶頸之一。1992年， ESTIM0V推薦了個人通信網（PCN )方案，這個起初稱為 DCS 1 800的系統因其技術GSM90 0非常類似，後來亦有人稱 其為GSM1 800。 G S Μ雙頻網實際上就是G S Μ兩個頻段數位移動通信系殊 、 網路的疊加。希望結合G S Μ 9 0 0與1 8 0 0的優點，以資源分享 的理念，加強訊號涵蓋區域，並增加系統容量，使得網路 資源得到最大的經濟效益。 目前市面上除了常見的雙頻手機外，還常見到三頻手& 機。所謂的三頻手機，是指在90 0MHz、1 800MHz外，加入 了美國所使用的1 900MHz，提供使用者到美國旅行或洽公 時，仍可透過漫遊使用同一台手機。 由於頻率的資源有線，一些國家近期向GSM/GPRS系統System 'is a GSM system. GSM (GlobalSystem for Mobile Communications) pan-European digital mobile communication system, often referred to as the second generation of digital mobile phones. In the development of GSM in just a few years, GSM900MHZ has become the leading standard for digital networks in the world. Most GSM operators worldwide have chosen the 90 MHz frequency band. With the scarcity of GSM900 frequency resources, it has become one of the bottlenecks in the development of mobile phone networks. In 1992, ESTIM0V recommended a personal communication network (PCN) solution. This system, originally called DCS 1 800, was very similar to its GSM900 technology, and was later called GSM1 800. The GSM dual-frequency network is actually a superposition of the digital mobile communication system and network of the GSM two frequency bands. It is hoped that combining the advantages of GSM 900 and 1800, and using the concept of resource sharing, to strengthen the signal coverage area and increase the system capacity, so that network resources can get the maximum economic benefits. In addition to the common dual-band mobile phones on the market, tri-band handsets are also common. The so-called tri-band mobile phone refers to the addition of 900 MHz and 1 800 MHz to the 1 900 MHz used in the United States. Users can still use the same mobile phone through roaming when traveling or visiting the United States. Due to the frequency of wired resources, some countries have recently adopted GSM / GPRS systems.
M260886 四、創作說明（2) 新開放了 85 0MHz頻段。在美國，8 5 0MHz主要使用於增強大 城市擁有高密度地區的網路能力，在南美洲，許多國家只 採用850MHz頻段。為實現手機的全球漫遊無阻礙，無疑地 增加8 5 0MHz頻段的四頻手機是有需要的。 隨者通k技術的發展，目前手機收發信機由雙頻，發 展至三頻、四頻，然而相對應的四頻天線設計要面臨的， 不是只有更高的頻段帶寬要求，還包括了目前手機外型朝 向輕薄短小的發展趨勢。 一般我們所見的雙頻行動電話手機的天線，是在兩個M260886 IV. Creative Instructions (2) The 85 0MHz band is newly opened. In the United States, 850 MHz is mainly used to enhance the network capacity of large cities with high-density areas. In South America, many countries use only the 850 MHz band. In order to achieve unhindered global roaming of mobile phones, it is undoubtedly necessary to add a quad-band mobile phone in the 850 MHz band. With the development of k-pass technology, mobile phone transceivers have evolved from dual-band to tri-band and quad-band. However, the corresponding design of quad-band antennas is not limited to higher frequency band requirements. The model is trending towards light, thin and short. Generally, the antennas of dual-band mobile phones we see are in two
頻段工作，也就是透過同一天線實現雙頻段的收發。此類 天線具有兩個不同的諧振點，及低頻段諧振點極高頻段諧 振點。其中，低頻段通帶範圍為·· 880-960MHz (GSM9 0 0 )，高頻段通帶範圍為一 188〇關2 (DCS 1 80 0 )。為了符合整體手機輕薄短小的設計要求， 天線的面積受到手機機殼内之空間限制而無法有較大的尺 寸。之後出現的三頻手機天線，是透過加寬高頻段諧振通 帶範圍而得。按照此種設計思想，我們一般可以透過加寬 低頻段通帶範圍來設計所需之四頻天線。Frequency band operation, that is, dual-band transmission and reception through the same antenna. This type of antenna has two different resonance points, and a low-frequency resonance point and an extremely high-frequency resonance point. Among them, the low-frequency passband range is 880-960MHz (GSM900), and the high-frequency passband range is 188 ° 2 (DCS 1800). In order to meet the requirements of light, thin and short overall mobile phones, the area of the antenna is limited by the space inside the mobile phone case and cannot be larger. The subsequent tri-band mobile phone antennas were obtained by widening the high-frequency resonance passband range. According to this design idea, we can generally design the required four-band antenna by widening the low-band passband range.
然而，此類雙頻天線之諧振振子並非是獨立協調的 每一個未用振子即是已用振子的寄生負載。在這種情況 下，如果想透過調整天線的結構來同時獲得8 1 71 0-1 990MHz的通帶範圍，是非常難以實現的。硬要將 通帶範圍的頻段整合在一起所設計出的手機天線，益法 到所需要的帶寬’也因此大大影響了整個手機的接&性However, the resonant oscillators of such dual-frequency antennas are not independently coordinated. Each unused oscillator is a parasitic load of a used oscillator. In this case, it is very difficult to achieve the passband range of 8 1 71 0-1 990MHz at the same time by adjusting the structure of the antenna. The mobile phone antenna that is designed to integrate the frequency bands in the passband range to benefit the required bandwidth ’has also greatly affected the accessibility of the entire mobile phone.
