【摘要】 本文提出了一种性能良好的S波段单馈点宽波束宽角圆极化微带天线。该天线具有优良的圆对称波束、半功率波束宽度110度、200度宽角范围内轴比小于3dB、增益5.1dBi,且同时具有体积小、重量轻、剖面低等优点。文中给出了设计仿真和实测结果,两者能够很好的吻合。该天线适用于LEO星载天线单元及GPS等相关应用。更多还原

【Abstract】 A S-band wide-angle circular-polarization(CP) microstrip patch antenna using a tuning stub is proposed and experimentally studied.The presented antenna shows a better wide-angle CP within 200deg,excellent circular beam,better impedance match and a stable gain level of 5.1dBi,which is obtained across the operation bandwidth.Details of antenna design and experimental results are proposed,which compared with excellent agreement.The constructed prototype is suitable for LEO satellite antenna system,as well as GPS related application.更多还原
