摘　　要：采用具有紧凑尺寸特征的高阻抗表面蘑菇状电磁带隙结构(EBG)做为双面印刷偶极子天线的反射板,利用HFSS电磁仿真软件模拟对传统金属良导体(PEC)反射板结构以及EBG反射板结构双面印刷偶极子天线的主要参数进行了对比研究。研究表明:采用EBG结构后可降低传统天线的高度约55%,同时提高天线增益约1.9dB。In this paper, a double-sided printed dipole （DSPD） array backed by an EBG retlector is proposed for achieving a low-profile design as well as gaining enhancement. Simulation results show that a reduction of more than 55% in antenna height can be obtained by placing the DSPD array over an EBG reflector rather than a perfect electric conductor （PEC） reflector, the obtained gain of the antenna with an EBG reflector is about 1.9db higher than that of a PEC reflector, and the operating frequency 2.77G Hz. The design has a good potential application to antenna arrays with more elements in wireless communication.
