摘　　要：目前设置的毫米波频段为28 GHz、38 GHz、60 GHz,为了提高微带贴片天线在60 GHz的整体辐射效率和带宽,设计一种由基片集成波导(SIW)馈电的微带贴片天线。为了获得更大的带宽,采用圆形与同心寄生圆环贴片结合的形式获得两个谐振频率,并且同时在辐射贴片上激励出TM11模式。仿真优化结果表明,该天线的阻抗带宽为40%,增益达到6.75 dBi,实测结果与仿真结果吻合良好。The millimeter⁃wave frequency bands currently are 28 GHz,38 GHz,and 60 GHz.In order to improve the overall radiation efficiency and bandwidth of the microstrip patch antenna at 60 GHz,a microstrip patch antenna fed by substrate integrated waveguide(SIW)is designed.In order to obtain a larger bandwidth,two resonant frequencies are obtained by combining circular and concentric parasitic annular patches,and the TM11 mode is excited on the radiating patch.The simulation optimization results show that the impedance bandwidth of the antenna is 40%,the gain is 6.75 dBi,and the measured results are in good agreement with the simulation results.
