A Broadband Dual-polarized Capped Bow-tie 2×2 Antenna Array for 28 GHz Band in 5G Systems
Paper in proceedings, 2018

With the development of the fifth generation (5G) communications, dual-polarization base station antennas have increasingly attracted a lot of attention. In this paper, a broadband high-gain efficiency dual-polarization polarized capped bow-tie antenna with parasitic directorsarray is presented. Simulation results show that the bandwidth of the proposed antenna is 24-36.8 GHz, with its return loss better than 10 dB and the stable coverage. The directivities vary from 8 to 12dBi and the relative cross-polar level is below -10dB over the most of band. It has a simple and compact structure, and is ready to be extended for an large array antennas with massive MIMO performance used in 5G communications.
