A Novel Design of Dual-feed Single-element Antenna for 4G MIMO Terminals

A novel design of dual-feed single-element antenna for 4G multiple input-multiple output (MIMO) terminals is proposed and analyzed in this paper. The antenna consists of a radiating patch which is fed by two input ports. The proposed antenna is a promising candidate for MIMO systems. With the presence of the crossover, the signal from the left port will excite for the right part of antenna and vice versa. The antenna shows high performance such as good isolation less than i15dB GHz, return loss less than i10dB in the frequency band ranging from 1.92GHz to 2.17GHz, covering the UMTS IMT band for 3G/4G wireless communications.
