摘要

微带贴片阵列天线在星载雷达和卫星中的应用日益广泛。本文介绍了一种工作在Ku波段(12 GHz ~ 18 GHz)和K波段(18 GHz ~ 27 GHz)的阵列天线，用于雷达和立方体卫星的应用。所设计的天线由64个双馈辐射单元组成，以2个子阵列的形式布置。16个单元组成4个子阵列，单馈线与中心馈线相连。分析了所有的2、4和8阵列，其中8阵列具有更高的带宽、高增益和显著的回波损耗。为了实现雷达和/或立方体卫星应用的天线，高增益、高带宽和多输出是先决条件，在这里实现。为了便于理解，天线的性能参数在附录部分以表格形式表示。

Design and Performance Analysis of a Multiband Microstrip Patch Array Antenna at Ku and K Band

Utilization of microstrip patch array antenna in space borne radar and satellite application is widespread nowadays. An array antenna operating at Ku band (12 GHz to 18 GHz) and K band (18 GHz to 27 GHz) for radar and cube-sat applications is presented in this paper. The designed antenna consists of 64 dual feed radiating elements arranged in a 2⨯2 sub-array configuration. A block of 16 elements constitute of four 2⨯2 sub-array are excited with single feed line connected with central feed. All 2⨯2, 4⨯4 and 8⨯8 arrays are analyzed, where 8⨯8 array illustrates higher bandwidth, high gain and significant return loss with multiple output. To implement the antenna for radar and/or cube-sat application, high gain, high bandwidth and multiple output are the prerequisites, which are achieved here. The performance parameters of the antenna are represented as the tabular form in the appendix section for better understanding.
