摘要

提出了一种双孔径耦合激励的周期结构双极化微带天线。提出了一种具有高端口隔离度的双极化进给机构设计方案。仿真结果表明，该方案在S11小于-10 dB的情况下，具有50%的相对带宽，在通带范围内端口隔离度高于38 dB。获得了最大增益为10 dBi的轴视辐射性能，总高度仅为0.047 λ0， λ0波长为4 GHz。

Dual-polarized Low-Profile Broadband Microstrip Antenna

A dual-polarized microstrip antenna based on a periodic structure is proposed with a dual aperture coupling excitation. A novel feeding mechanism is proposed for the dual-polarization design with a high port isolation. Simulation results show that it has a relative bandwidth of 50% with the |S11| less than -10 dB and the simulation result of port isolation is higher than 38 dB over the passband. Boresight radiation performance has been obtained with a maximum gain of 10 dBi, and the overall height is only 0.047 λ0, λ0 is wavelength for 4 GHz.
