介绍了一种新型基片集成波导背腔六边形缝隙线极化天线。背腔缝隙天线是一种技术成熟的天线类型,但是笨重的体积限制了传统金属腔体缝隙天线的发展。基于基片集成波导结构的背腔缝隙天线以其低损耗、高功率容量、高增益 以及易集成等诸多优点而备受关注。文中设计了一款基于基片集成波导加开六边形缝隙的背腔天线,通过CST软件仿真,并制作了天线实物进行测试。天线的中心工作频率为10 GHz,增益为4. 87 dB,带宽为147 MHz。

A novel linear polarized substrate integrated waveguide cavity-backed antenna with hexagonal slot is introduced. The development of traditional metal cavity slot antennas with bulky size is limited while it's a well-established antenna type. The substrate integrated waveguide technology has been widely used since its introduction, and the cavity-backed slot antenna based on it is favored by researchers because of its low loss level, high power capacity, high gain and easy integration. Through simulation of CST, a cavity-backed antenna with a hexagonal slot based on the integrated waveguide substrate is designed and fabricated. The center frequency of the antenna is 10 GHz, the corresponding gain is 4. 87 dB, and the bandwidth is 147 MHz.
