技术领域technical field
本发明属于通信技术领域,具体涉及一种金属边框手机的多频段天线双开关结构及其方法。The invention belongs to the technical field of communication, and in particular relates to a multi-band antenna double switch structure of a metal frame mobile phone and a method thereof.
背景技术Background technique
天线的作用在于将射频信号进行有效地发射和有效地接收,而天线的谐振支路都是有频率带宽的,随着通信的发展,对天线覆盖带宽的要求越高。当前,随着新一代无线通信技术的发展,用于无线通信的频段数量大大增加,因此常常需要考虑设计可用于多个工作频段的多频段天线,现阶段我国的第五代移动通信技术得到了快速的发展的应用。而天线作为移动通信系统的重要组成部分,发挥着重要的作用,因此5G多频段天线的研究设计在移动通信终端中有广阔的应用前景,目前市场上手机多频段天线设计普遍采用的是直接馈电或者断口单边馈电耦合技术设计思路,这两种技术在现有市场上的金属边框对称断开手机项目上应用很广;The function of the antenna is to effectively transmit and receive radio frequency signals, and the resonant branch of the antenna has a frequency bandwidth. With the development of communication, the requirements for the coverage bandwidth of the antenna are higher. At present, with the development of a new generation of wireless communication technology, the number of frequency bands used for wireless communication has greatly increased, so it is often necessary to consider the design of multi-band antennas that can be used in multiple operating frequency bands. Rapidly developing applications. As an important part of the mobile communication system, the antenna plays an important role. Therefore, the research and design of 5G multi-band antenna has broad application prospects in mobile communication terminals. The design idea of unilateral feeding coupling technology of electricity or fracture, these two technologies are widely used in the project of symmetrical disconnection of metal frame in the existing market;
但是,现有的设计思路存在的问题点如下:However, the existing design ideas have the following problems:
1、直接馈电对金属断片长度以及天线净空区域要求严格,调试天线往往带宽不够满足多频段需求,不适用于堆叠紧测的手机项目;1. Direct feeding has strict requirements on the length of metal fragments and the clearance area of the antenna. The bandwidth of the debugging antenna is often not enough to meet the multi-band requirements, which is not suitable for mobile phone projects with stacking and tight testing;
2、单边馈电耦合技术的问题点在于所有需要的频段均需要承载在一个天线开关上,天线开关的选择是个难点。如果选择单刀多掷开关,开关的路径不够满足天线频段需求。如果选择的是可调电容,那么会面对调试频段范围与可调电容本身承载电压存在矛盾。2. The problem with the unilateral feed coupling technology is that all the required frequency bands need to be carried on one antenna switch, and the selection of the antenna switch is a difficult point. If a single-pole, multi-throw switch is selected, the path of the switch is not sufficient to meet the antenna frequency band requirements. If an adjustable capacitor is selected, there will be a conflict between the debugging frequency range and the voltage carried by the adjustable capacitor itself.
如何解决上述两个技术难点是需要进行研究的。How to solve the above two technical difficulties needs to be studied.
