摘要
主要阐述了一个新颖的X波段4×4单元微带阵列天线的设计方法。阵列天线辐射单元采用空气介质的微带贴片天线,辐射效率高;阵列天线的馈线网络采用低损耗的空气带状线形式,降低了馈线损耗。详细给出了微带贴片天线设计公式和阵列天线阵间距的选择。阵列天线性能优良,已成功地应用到某X波段光电雷达项目中。
A novel X-band microstrip array antenna is presented in the paper, which is 4×4 elements. The radiating element of array antenna is air dielectric microstrip patch antenna,which has high efficiency,and the feed network is low loss air strip,which can reduce the loss of the feed line. The design equation of the microstrip patch antenna and the element gap of the array antenna have been given. The antenna has good performance,it is used in the equipment of the X-band light-electric radar.
