基片集成波导圆极化天线的设计
Design of Circularly Polarized Antenna Based on Substrate Integrated Waveguide
摘要
介绍了一种基于单基片的新型背腔圆极化缝隙天线。运用了HFSS电磁仿真软件对天线进行优化仿真, 在中心频率为12 GHz时, 最大增益为7. 3 dB, 最小轴比为1. 03 dB。仿真结果表明, 该天线具有高增益、低轴比、成本低、易于制造等优点。
Abstract
A new type of circularly polarized antenna based on Substrate Integrated Waveguide (SIW) is introduced. HFSS simulation software is used for the optimization of the antenn The maximum gain is 7. 3 dB, and the Axial Ratio (AR) is 1. 03 dB when central frequency is 12 GHz. The simulation result shows that the new antenna has high gain and low AR, and also has the advantages of cheap and easy to fabricate.
