The elliptical planar monopole antenna has the advantages of simple structure, wide band and relatively simple feed, so it can meet the demands of wide-band and high-gain at the same time.
Two coherent signals with different primary phases radiated by two orthogonal in-space linear polarization antenna elements form an elliptical polarization wave.
两个初相不同的相参信号由两个在空间上正交的线极化天线单元辐射，将形成椭圆极化波。

The hybrid structure constituted of the elliptical and rectangular shapes has been adopted in the antenna design.
