摘要
设计了一种工作在C波段的宽带微带单脉冲阵列天线,采用口径耦合馈电和附加寄生贴片方式拓展微带天线带宽,利用三分支定向耦合器结构设计宽带微带和差网络,并与4×4微带阵列天线组成宽带单脉冲阵列天线,设计仿真后加工实物,经过实测,天线工作带宽1.2 GHz。
A wideband microstrip monopulse array antenna operating in C band is designed.The bandwidth of the microstrip antenna is expanded by means of aperture coupling feed and additional parasitic patch.The wideband microstrip sum-difference network is designed by using the three-branch directional coupler structure.The sum-difference network and 4×4 microstrip array antenna are cascaded to form a wideband monopulse array antenna.After design and simulation,the real object is processed.Actual measurement shows that the antenna bandwidth is 1.2 GHz.
