摘　　要：设计了一种用于连续波雷达的X波段水平极化阵列微带天线,天线阵列由中心馈电的微带贴片单元组成。采用行波串馈的形式,通过在天线两侧安装两块金属板,压窄了俯仰面的波束宽度,提高了收发天线隔离度。实测结果与仿真结果一致性比较好,在9.3~9.4 GHz的工作带宽范围内,驻波比小于1.35,副瓣低于-22 dB,收发天线隔离度大于60 dB。This paper designs a type of X-band horizontal polarization array microstrip antenna used for continuous wave radar.The antenna array consists of microstrip patch units fed from the center.Using the traveling-wave series feed mode, the beam width of elevation surface is reduced, and the isolation of transceiver antenna is improved by adding two metal plates on both sides of the antenna.The measured results are in good agreement with simulation results.The voltage standing-wave ratio(VSWR) is less than 1.35,the side lobe is less than-22 dB,and the isolation of transceiver antenna is more than 60 dB in the operating bandwidth of 9.3~9.4 GHz.
