SRR Loaded Wideband Antenna 5G Application

5G communication systems ensure high data rate, low latency, network reliability, and energy efficiency and high throughput that require new and very efficient antenna designs. In this paper, we proposed a simple and very effective antenna with centre frequency 28GHz designed on an RF4 substrate of 1. 6mm thickness. The performance characteristics of the antenna-like reflection coefficient (Sll), voltage standing wave ratio (VSWR), radiation pattern and impedance have been investigated using HFSS. optimization techniques are applied to achieve significant results. A defective ground structure was chosen for obtaining proper impedance matching. The simulated results are satisfactory and the proposed antenna is a good candidate to operate in the millimetre wave frequency band that is 28GHz range for 5G application.
