Abstract

To design a multiband microstrip patch antenna, the Defected Ground Structure (DGS) technique is applied to add a disturbance effect in the surface current distribution and create a multi-resonance frequency. Furthermore, and in the aim to achieve a high gain, a high superstrate is added above the basic antenna design. The developed antenna is dedicated to the 5G sub 6GHz band application. The proposed antenna is based on RO5880 dielectric substrate of ϵ=2.2 and has an overall dimension of 77×70.11×1.6 mm3. The antenna operates at a sub 6GHz frequency range (at 4.53 to 4.97 GHz) and fits in 5G band application standard. Using CST Studio Suite Electromagnetics (EM) Solver, antenna's performances are investigated; an average gain of 5 dB with acceptable radiation efficiency is obtained at the operating frequencies, suitable for sub-6GHz 5G application. The proposed antenna is fabricated, and experimental analysis is conducted using ROHDE & SCHWARZ ZVB20 network analyser, which shows a good agreement with the simulation analysis.
