基于高阻表面微波光子晶体的微带天线设计

内容简介：利用高阻表面具有明显表面波带隙的特性,研究微波光子晶体高阻表面结构在中心频率为11.75 GHz微带天线中的应用.高频结构仿真(HFSS)电磁软件建模仿真结果表明,微带天线增益提高约为0.6 dB,低背瓣辐射最大降低约为10 dB,从而提高了天线的性能.

Abstract：A microstrip antenna based on high-impedance surface of microwave photonic crystals was proposed,which works on a centre frequency of 11.75 GHz.High impedance surface can improve the characteristics of surface wave band gap.Simulation by HFSS shows that microstrip antenna gain increased around 0.6 dB and low back lobe radiation maximum reduced around 10 dB.Thus the overall performance of the antenna is improved.
