Microstrip quasi-Yagi antennas of small size and light weight are introduced to address the disadvantages of large size and heavy weight of C-band microwave communication system antennas.A C-band 1×2 microstrip quasi-Yagi antenna array is designed, simulated and optimized,and its structural parameters are extracted. The antenna array is fabricated and its performance is tested. The results of simulation and test are consistent with each other,the gain is more than 10 dB,and the S11 is lower or equal to -10 dB.%针对C波段微波通信系统中应用的天线体积大、重量重的缺点，简要介绍了体积小、重量轻的微带准八木天线，设计了一种1×2微带准八木天线阵列，对该天线阵列进行了仿真和优化，提取了天线的结构参数，加工了阵列天线实物并进行了性能测试。将仿真结果与测试结果进行了比较，从结果中可以看出，天线的测试结果与仿真结果基本一致，天线的增益大于10 dB，回波损耗S11≤-10 dB。
