摘要：
In this work, a broadband circularly polarized (CP) antenna with omnidirectional radiation and high gain is proposed for base station applications. The antenna consists of full wavelength strips, half wavelength strips and half wavelength loops in series, which ensure the in-phase currents along the antenna. The impedance bandwidth of the antenna is 3.3-3.89 GHz, whereas the axial ratio bandwidth is 3.35-3.97GHz. As a result, an overlapping bandwidth of 3.35-3.89GHz is achieved, mostly covering the band for 5G communications. The maximum antenna gain is 8.85 dBic.
