Description of the Invention: [Technical Field] The present invention relates to an antenna for a mobile phone communication terminal, and more particularly to an antenna disposed in a mobile phone communication terminal for processing transmission/reception signals. ‘ 【Prior Art】, the current mobile phone communication terminal has developed towards a miniaturization and weight * light trend and provides different services. In order to meet these requirements, the internal circuits and components applied to the above-mentioned mobile phone communication terminal must be developed in a variety of functions and miniaturization. Such a trend also applies to an antenna, which is one of the important components of the above-mentioned mobile phone communication terminal. * A helical antenna and a planar anti-F-type antenna (hereinafter referred to as PIFA) are used in the mobile phone communication terminal. The above-mentioned helical antenna system SJ A is to the external antenna at the upper end of the above communication terminal, and It is used to connect with a monopole antenna. When an antenna assembly including the above-mentioned spiral antenna and monopole antenna is extended from one main body of the antenna, the antenna assembly is used as the monopole antenna, and When the antenna component is indented into the main body of the antenna, the antenna is used as a λ/4 helical antenna.
上述螺旋狀天線與單極天線之一組合結構且有一 高的增益之優點。然而’上述螺旋狀天線與單極天線 之組合結構由於它的無方向性以致於具有-高的SAR 5 1315112 特性。此處’上述SAR特性是_個對於人體有室之一 電磁波指標。由於上述螺旋狀天線是伸出上述行動電 話通訊端之外的’因此要設計出美觀地與可攜帶式之 上述螺旋狀天線是困難的。再者，上述單極天線需要 一個上述天線内之足夠的儲存空間。因此，上述螺旋 狀天線與單極天狀組合結構限制了—湘該結構之 行動電話通訊端產品之小型化。 為了解決上述問題’提出一個具有一小的外觀钍 構之平面反F-型天線（PIFA)。圖一所示為一傳統的平 面反F-型天線（PIFA)之一示意圖。上述平面反&型天 線(PIFA)包括-輻射單元2、-短路引線(pin)4、一同 軸電纜5與一接地板9。電力係透過上述同軸電纜5而 電饋到上述輻射單元2,並且上述輻射單元2透過上述 短路引線(pin)4而產生短路於上述接地板9，結果達到 阻抗匹配。上述平面反F_型天線（PIFA)之設計必須考 慮上述輻射單元2之長度（L)、依據上述短路引線(pin)4 之寬度（WP)之上述天線之高度（H)與上述輻射單元2之 寬度(W)。 在這個平面反F-型天線（PIFA)中，其中之電波係 藉由上述輻射單元2之感應電流產生，直接朝向一接 地板之電波再被感應，結果降低了上述電波置接朝向 人體並且提昇了上述SAR之特性。再者，朝向上述輻 射單元2之上述感應電波增加了。這個平面反F_型天 線(PIFA)可以作為一具有上述輻射單元2之長度變成 1315112 一半之方形微條天線，以達到—小的外觀結構。再者， 上述平面反F_型天線(PIFA)是—安置於上述行動電話 通a端中之内置天線，結果成為美觀的設計並且可以 防止外來的撞擊。

上述傳統的内置F-型雙頻帶天線一般係用於一具 有大的空間提供給於天線之條型端中。然而，上述傳 統的F-型天線具有_個大的尺寸，因此需要一個相當 大的儲存空間於上述通訊端中。再者，如果上述傳統 的F-型天線是在一個小尺寸中被製造，上述天線之一 個有用的頻帶是窄的並且上述天線會不容易受到外在 的應力所影響’也就是說，上述天線之增益之退化。 制地，如果上述傳統的F型雙頻帶天線是被利用在

with one of the monopole antennas and has the advantage of high gain. However, the combination of the above-described helical antenna and monopole antenna has a high SAR 5 1315112 characteristic due to its non-directionality. Here, the above SAR characteristics are one of the electromagnetic wave indicators for one of the human body. Since the above-mentioned helical antenna extends beyond the communication terminal of the above-mentioned mobile phone, it is difficult to design the above-described helical antenna which is aesthetically pleasing and portable. Furthermore, the monopole antenna described above requires a sufficient storage space within one of the above antennas. Therefore, the above-mentioned helical antenna and the monopole-shaped combined structure limit the miniaturization of the mobile phone communication terminal product of the structure. In order to solve the above problem, a planar inverse F-type antenna (PIFA) having a small appearance structure is proposed. Figure 1 shows a schematic diagram of a conventional planar inverted F-type antenna (PIFA). The above-mentioned planar anti-amplitude antenna (PIFA) includes a radiation unit 2, a short-circuiting pin 4, a coaxial cable 5 and a grounding plate 9. The power is electrically fed to the radiating element 2 through the coaxial cable 5, and the radiating element 2 is short-circuited to the grounding plate 9 through the short-circuiting pin 4, and as a result, impedance matching is achieved. The above planar inverted F_type antenna (PIFA) must be designed in consideration of the length (L) of the radiating element 2, the height (H) of the antenna according to the width (WP) of the shorting lead 4, and the radiating element 2 described above. Width (W). In this planar anti-F-type antenna (PIFA), the electric wave is generated by the induced current of the radiating unit 2, and the electric wave directly directed to a grounding plate is induced again, thereby reducing the above-mentioned electric wave to be attached to the human body and elevating The characteristics of the above SAR. Furthermore, the above-mentioned induced electric wave toward the above-described radiation unit 2 is increased. This planar anti-F_type antenna (PIFA) can be used as a square microstrip antenna having the length of the above radiating element 2 to become 1315112, to achieve a small appearance structure. Furthermore, the above-described planar anti-F_type antenna (PIFA) is an internal antenna disposed in the a side of the above-mentioned mobile telephone, and as a result, it is an aesthetically pleasing design and can prevent an external impact. In order to satisfy the above-mentioned multi-functional trend, the above-mentioned plane anti-F_type antenna (PIFA) has undergone many modifications. In particular, a dual band chip antenna operating in different frequency bands has been developed. Figure 2a is a diagram of a conventional built-in F_type dual-band antenna. Referring to Figure 2a, the conventional F-type dual-band antenna (7) includes a (four) unit 20, an electric feed pin 25 and a ground lead (pm) 26. The radiating element μ of the above-mentioned conventional F_ type dual-band antenna includes one for processing - a high-band radiation single-input 21 in the center and the region of the high-band signal, and a low-band light-singing single-single in which the low-band signal is processed. 23 and 24, the low-band radiating elements 22, 23 and the edge of the high-band radiating element 21 are separated from the high-band radiation: element 21 by a specified distance. That is, the above-described low-band radiation units 22, 23 and 24 are connected in parallel to the above-described high-band light-emitting unit 21. The above-mentioned electric feed pin 25 and ground pin 26 are connected to one end of the above-mentioned radiation unit 2''. Figure 2b is a schematic diagram of one of the current paths of a conventional built-in F_type dual-band antenna. As shown in Fig. 2b, the currents 27 and 28 respectively pass through the above-mentioned electric feed lead _) 25 to respectively introduce the above-mentioned high-band radiation unit 21 and low-frequency 7 1315112 t shot sheets 70 22, 23 and 24. The high-band light-emitting unit 21 is a current 27 introduced by the high-band radiation unit 21 to radiate a gate frequency radio wave signal. Furthermore, the low-band radiating elements, six', 24, emit low-frequency radio wave signals by the electrical cores 28 introduced by the low-band light-emitting units 22, 23. The above conventional built-in F-type dual band antenna is generally used for a large space to be supplied to the strip end of the antenna. However, the above conventional F-type antenna has a large size, and therefore requires a considerable storage space in the above communication terminal.
