摘　　要：本文提出了一款加载短枝节的宽带天线和基于超表面的多层宽带天线。前者通过在微带馈电线上加载短路枝节使得天线的带宽有所增加。在本文中通过在微带馈电线上加载短路枝节拓展了天线带宽。在尽量不改变平面尺寸的情况下,加载双层覆着矩形贴片的介质基板使天线获得多频的特性。在多层结构的天线中加载超表面结构和金属反射板,进一步的提升天线的带宽和增益,并相对减小天线的平面尺寸,从而达到了天线小型化、多频化、宽带化。A broadband antenna loaded with short branches and a multilayer broadband antenna based on hypersurface are proposed in this paper. The former increases the bandwidth of the antenna by loading short-circuit branches on the microstrip feeder. In this paper, the antenna bandwidth is expanded by loading short-circuit branches on the microstrip feeder. Under the condition of not changing the plane size as much as possible, the antenna can obtain multi frequency characteristics by loading a double-layer dielectric substrate covered with rectangular patches. The super surface structure and metal reflector are loaded into the multi-layer structure antenna to further improve the bandwidth and gain of the antenna, and relatively reduce the plane size of the antenna, so as to achieve the miniaturization, multifrequency and broadband of the antenna.
