摘要

研究了一种由阵列天线和小型化收发模块组成的膜相控阵天线在GEO SAR中的应用。采用有限元法对阵列天线的辐射方向图进行了分析。设计开发了体积小、重量轻的T/R模块。在此基础上，设计、制作并测量了1 × 4元相控阵样机。测试结果表明，在1.16 GHz ~ 1.24 GHz范围内，相控阵的驻波比小于1.5，在接收和发射模式下的转向角分别为$\pm 30^{\math {o}}$。计算结果与实验结果吻合较好。

A Membrane Phased Array Antenna Base on Miniaturized Transmit/Receive Modules for GEO SAR Application

A membrane phased array antenna consists of an array antenna and miniaturized transmit/receive (T/R) module is investigated for GEO SAR application. The radiation pattern of the array antenna is analyzed with finite element method (FEM). The T/R module with compact size and light weight is designed and developed. Based on these research, a prototype of the $1 \times 4$ element phased array is designed, fabricated and measured. The test results show that the VSWR of the phased array is less than 1.5 from 1.16 GHz to 1.24 GHz, the steering angles is $\pm 30^{\mathrm{o}}$ in receive and transmit modes, respectively. The calculated results are in good agreement with the experimental results.
