一种三极化复合天线

A Compound Tri-polarization Antenna

提出了一种工作在L频段的三极化复合天线。天线具有三个端口,可分别接收空间中相互正交的三个极化电场分量。利用双馈点微带天线实现水平面相互正交的两个线极化,单极子天线实现垂直极化。单极子天线位于微带天线中心,与微带天线共地,实现三种极化的复合设计。对该天线进行了加工并测试,验证了设计的合理性。

This paper presents a compound tri-polarization antenna which works on L band.The antenna contains three ports which can receive three orthogonal electric components from space.A doubly fed microstrip antenna is applied to achieve two orthogonal polarization in horizontal plane,and a monopole is used to realize vertical polarization.The monopole is located on the centre of the microstrip antenna,and they share the ground,then the compound design of three polarizations can be realized.At last,the tri-polarization antenna is fabricated,and the measured results verified the proposed design.
