      Circular polarization microstrip antenna at W band

        摘要
      • 摘要: 研究了不同馈电形式的W波段圆极化微带天线阵列，并采用等幅同相馈电方式以及新型波导到微带过渡结构，完成了圆极化阵列天线的设计.由理论分析和仿真结果可知，通过选择合适的介质，以及利用单元间等幅同相馈电，既能有效减小W波段天线的损耗，又能实现圆极化的良好轴比特性.功分网络的合理排布，波导到微带过渡结构亦有利于减小天线损耗.对8×8阵列天线进行实测，S(1，1)小于-15 dB的相对带宽为43%，轴比小于3 dB的波瓣宽度为11°，中心频点94 GHz时天线增益为206 dB，与仿真结果基本吻合.

         

        Abstract: A circular polarization array antenna at W band is designed by analyzing and comparing different feeding forms，using constant amplitude and inphase feeding and waveguidemicrostrip transition.According to the theoretical analysis and simulation results，the loss of W band antenna can be reduced，good axial ratio and suitable arrangement of feeding network can be realized by choosing proper dielectric，using waveguidemicrostrip transition and constant amplitude and inphase feeding of each unit radiation patch，which is ideal for the realization of circular polarization array antenna at W band.The bandwidth of the 8×8 array antenna are 43% when S(1，1)<〖KG-*4〗-15 dB.The beamwidth of the antenna is 11° when axial ratio is below 3 dB.And the maximum achievable gain of this antenna is 206 dB.Test and simulation results are in good agreement.
