Abstract

In this paper, a dual circularly polarized antenna array with a compact feeding network is proposed for millimeter-wave applications. The antenna element consists of four sequentially rotated patches fed by a high-order mode cavity to reduce the dielectric loss in the feeding network. Right-hand circular polarization(RHCP) and left-hand circular polarization(LHCP) are achieved by adopting a coupler and a phase shifter between the two input ports. The measured and simulated results agree well, showing its good performance of high gain and wide impedance bandwidth.
