摘要
为了满足多频段通信应用中天线抗金属平台的要求,提出了一种带反射板可调多频段蝶形天线,包括平行设置的单层天线基板和金属反射板。可通过螺丝钉调节单层基板和金属反射板之间的间距,从而实现调节天线频率。单层基板上的天线包括上表面连接有微带线的钥匙形辐射单元、下表面的蝶形辐射单元和波峰形接地端,目的是实现天线多频辐射。仿真和测试结果表明,该天线能同时工作在0.44 GHz/0.635 GHz/1.735 GHz/2.45 GHz多个频段,可以放置在金属平台上使用,并可以和平面电路集成、结构简单。
In order to meet the application requirements of multiband communication on a metal platform,a multiband tunable butterfly-shaped antenna with reflector is proposed,which consists of a single antenna substrate and a metal reflector plate arranged in parallel. The distance between the antenna substrate and the metal plate can be adjusted by screws and the frequencies of the antenna can be tuned by adjusting the distance. The antenna on the substrate consists of a key-shaped radiation element connected with a microstrip on the top surface of the substrate,a butterfly-shaped radiation element and a peak-shaped ground on the bottom surface of the substrate,in order to achieve the multiband radiation of the antenna. The measurement results show that the antenna can work at 0.44 GHz/0.635 GHz/1.735 GHz/2.45 GHz at the same time. It can be placed on a metal platform and integrated with a planar circuit,having a simple structure.
