Description

一种耦合馈入式手机天线装置 Coupled feed type mobile phone antenna device
技术领域 Technical field
本发明涉及一种手机天线装置，具体地说是一种耦合馈入式手机天线装置。 The invention relates to a mobile phone antenna device, in particular to a coupled feed type mobile phone antenna device.
背景技术 Background technique
无线通信技术的蓬勃发展使得同一终端***上搭载的信息子模块越来越多，如当前的手机，特别是智能手机的***普遍搭载多种子通信模块，这些信息子模块的增加必然会导致天线频带的扩充和天线结构复杂度的增加。同时为了在日益竞争激烈的消费电子市场博得更多消费者的青睐，手机等产品均向着薄型化和强金属质感的方向发展，而薄型化和强金属质感的手持终端设备无疑给天线的设计带来了巨大的挑战。 The rapid development of wireless communication technology has led to more and more information sub-modules on the same terminal system. For example, current mobile phones, especially smart phone systems, are generally equipped with a variety of sub-communication modules. The increase of these information sub-modules will inevitably lead to the antenna frequency band. The expansion and the complexity of the antenna structure increase. At the same time, in order to win more consumers' favor in the increasingly competitive consumer electronics market, mobile phones and other products are moving towards thinner and strong metal textures, while thin and strong metal texture handheld devices are undoubtedly designed for antennas. A huge challenge has come.
当前的无线终端内置天线普遍采用平面倒F天线（PIFA）和单极天线（Monopole）。平面倒F天线由于对面积和高度的要求较高，严重限制了整机的布局以及轻薄化，同时由于多天线布局所限，而且PIFA天线受其辐射机理所导致其性能较差，而没有被大量采用。就单极天线而言，临近区域大金属件的存在对其无线性能无疑是致命的打击，那么如何解决手机设备金属件对天线性能的影响一直以来是该行业内研究的热点。众所周之，某公司产品的出世，让全世界为之疯狂，其中该手机利用了手机的侧面金属中框做成天线的一部分，成功地完成了天线的设计，但是遗憾的是后来出现了天线敏感问题，即当消费者在使用此产品进行通话时，如果手接触到其金属中框的其中一个缝隙处，天线性能严重恶化而影响正常的通话状态。 Current built-in antennas for wireless terminals generally use a planar inverted-F antenna (PIFA) and a monopole antenna (Monopole). Due to the high requirements on area and height, the planar inverted-F antenna severely limits the layout and lightness of the whole machine. At the same time, due to the limitation of multi-antenna layout, and the PIFA antenna is poorly affected by its radiation mechanism, it is not A lot of adoption. As far as the monopole antenna is concerned, the presence of large metal parts in the adjacent area is undoubtedly a fatal blow to its wireless performance. How to solve the impact of the metal parts of mobile phone equipment on the antenna performance has been a hot spot in the industry. Everyone knows that the birth of a company's products has made the world crazy. The mobile phone uses the side metal frame of the mobile phone to make part of the antenna, successfully completing the antenna design, but unfortunately it appeared later. The antenna is sensitive to the problem that when the consumer uses the product to make a call, if the hand touches one of the gaps in the metal frame, the antenna performance is seriously deteriorated and the normal call state is affected.

The resonance principle of the Loop antenna shows that the one-half wavelength of the loop is resonant in the 850/900 MHz band of the mobile phone, and one wavelength of the loop. Resonant in the DCS band of the mobile phone, part of the PCS band; 2) The antenna connector 302, the antenna radiator 201 and the antenna connector 304 are sequentially connected to form a high frequency parasitic branch of the antenna device, mainly generating resonance of the PCS and the UMTS part of the high frequency band, wherein the antenna connectors 302 and 304 can be Remove any of them according to your debugging needs.
特别值得注意的是，天线辐射体二202上开有一缝隙202-1，该缝隙的形状不限，可根据调试需要进行设计，该缝隙的形状主要包括有：直线型(如附图4中的202-1)、折线型(如附图4中的202-2)、斜线型(如附图4中的202-3)，弧线型(如附图4中的202-4)等。该缝隙的存在，使得射频馈源401从直接馈入的方式变成了耦合式，从而改变了Loop回路上的电流分布，使得金属装饰件上的缝隙105不再成为该天线装置的'敏感点'，从而解决了当人手紧握金属边框缝隙处时出现天线性能严重恶化的天线敏感问题。 It is particularly noteworthy that the antenna radiator 202 has a slit 202-1. The shape of the slit is not limited and can be designed according to the debugging requirements. The shape of the slit mainly includes: a straight type (as shown in FIG. 4) 202-1), a broken line type (such as 202-2 in Fig. 4), a diagonal line type (such as 202-3 in Fig. 4), an arc type (such as 202-4 in Fig. 4), and the like. The presence of the gap causes the RF feed 401 to change from direct feeding to coupling, thereby changing the current distribution on the Loop circuit, so that the gap 105 on the metal trim no longer becomes the 'sensitive point of the antenna device. ', thus solving the antenna sensitivity problem that occurs when the human hand grips the gap of the metal frame and the antenna performance is seriously deteriorated.
本发明可用于各种手持移动终端，与现有技术比较具有以下优点：（1）巧妙的利用手机外观金属装饰件作为手机天线的一部分，不仅解决了大金属件与天线共存的问题，同时极大地增强了手机的外观表现力；（2）通过耦合馈入代替直接馈入的方式，很好地解决了当人手紧握金属边框缝隙处时出现天线性能严重恶化的天线敏感问题； The invention can be applied to various handheld mobile terminals, and has the following advantages compared with the prior art: (1) skillfully utilizing the metal decorative parts of the mobile phone as part of the mobile phone antenna, not only solves the problem of coexistence of large metal parts and antennas, but also extremely The earth enhances the appearance of the mobile phone; (2) By coupling the feed instead of the direct feed, the antenna sensitive problem that the antenna performance is seriously deteriorated when the hand grips the gap of the metal frame is well solved;
（3）该天线采用Loop天线的形式，具有宽频带，高效率的特点，保证了手机优异的无线通信性能。 (3) The antenna adopts the form of a loop antenna, which has the characteristics of wide frequency band and high efficiency, and ensures excellent wireless communication performance of the mobile phone.
上述实施例中提到的内容并非是对本发明的限定，在不脱离本发明构思的前提下，任何显而易见的替换均在本发明的保护范围之内。 The above mentioned embodiments are not intended to limit the invention, and any obvious alternatives are within the scope of the invention without departing from the spirit of the invention.
