摘要
In this paper, a broadband elliptical-shaped slot antenna for the future fifth generation (5G) wireless applications is proposed. The antenna has a compact size of 0.5 lambda(0) x 0.5 lambda(0) at 30 GHz. It consists of a circular shaped radiating patch fed by a 50 Omega microstrip line via proximity-feed technique. An elliptically shaped slot is etched in the ground plane to enhance the antenna bandwidth. A stub has been added to the microstrip line feed to achieve better impedance matching bandwidth of the antenna. Simulated results indicate that the proposed 5G antenna yields a broadband impedance bandwidth larger than 67% (from 20 GHz to beyond 40 GHz) for S-11 less than -10 dB. The achieved bandwidth covers both future 5G bands (28/38 GHz). The proposed antenna provides almost omni-directional patterns, relatively flat gain, and high radiation efficiency through the frequency band excluding the rejected band.
