摘要 印刷偶极子天线由于具有体积小、频带宽等优点而被广泛用于许多领域。针对在某些场合需要E面全向辐射天线,设计了一个平面结构的宽带阵列天线,并利用电磁仿真软件HFSS进行仿真。天线采用了巴伦馈电的印刷偶极子作为基本单元,通过引入平面喇叭和反射单元来改善方向图不圆度,使其能在E面实现全向辐射。结果表明,它在3.5～6.5GHz的宽频率范围内的回波损耗基本在-10dB以下,E面方向图不圆度小于3dB,仿真与实测结果能够较好地吻合。 Printed dipole antenna is widely used in many fields because it has a lot of good performances such as small size,wide frequency band.For the requirement of E-plane omni-directional antenna in some cases,a broadband planar array antenna is designed and simulated by electromagnetic simulation software HFSS.The antenna uses printed dipole with balun feed as basic unit and improved its pattern un-roundness by adding planar horns and reflecting units to realize E-plane omni-direction radiation.The results show that the antenna has a measured bandwidth from 3.5GHz to 6.5GHz with return loss of generally less than-10dB,and its un-roundness is less than 3dB.The experimental result is in good agreement with simulation data.
