Abstract

A wideband omnidirectional dielectric resonator antenna (DRA) array has been proposed. The simulated results show that the return loss of the DRA array is less than -10dB in the frequency band of 1.61dB-2.92dB (57.8%), which can cover the 2G/3G/LTE bands simultaneously. In order to reduce the deterioration of the omnidirectionality of the DRA array, a new means to arrange the feeding coaxial cable is proposed. Based on this means, a wideband DRA array with a good omnidirectionality is designed, whose gain variation ranges from 0.11dB to 0.83dB over the operating band of 1.61GHz-2.92GHz. Besides, the maximum and minimum gain in the horizontal plane are 5.41dBi (at 2.73GHz) and 3.25dBi (at 1.61GHz), respectively. The proposed antenna in this article can be a good alternative in wireless communication systems.
