Design of a wideband Dual Polarized Antenna for Base Station
In this paper, a wideband dual polarized antenna for base station is proposed. The antenna consists of a reflector, a horizontal radiating patch, two Y shaped feeding structures and two coaxial cables. To increase the resonance modes, a nonuniform coupling chamfer is introduced. The bandwidth is widened by improving the shape of the edge of the antenna and etching the U shaped slot. The size of the antenna is 49.5mmx49.5mm. The antenna was manufactured and tested. The measured results show that the antenna operates from 1.7GHz to 3.7GHz with VSWR<2 (about 74.07% covering 2G band (1710MHz 1920MHz) 3G band (1880MHz 2170MHz) LTE band (2300MHz 2400MHz 2570MHz 2690MHz) and 5G band (3300MHz 3600MHz) A stable pattern and gain are achieved simultaneously in the entire operating band.
