A novel MIMO patch antenna for 5G applications

Abstract

In this paper, a new MIMO patch antenna is proposed, the proposed antenna consist of patch with certain dimensions in the top layer of FR-4 dielectric substrate, and ground plane in the bottom of it, this antenna is feeding by microstrip feed line with 50-ohm characteristic impedance. The dimensions of the proposed antenna are (50 × 50 × 1.6) mm3, the FR-4 epoxy substrate has relative dielectric constant er=4.3, loss tangent tan (d) =0.025. This antenna is realized a bandwidth of 4.337 GHz (24.22 – 28.557) GHZ and gain (3.68) dBi which is compatible with 5G applications. Some modifications were done in the ground plane and some of slots are etched on the patch to achieve the desired gain and bandwidth, all dimensions of these slots were chosen by using sweep parameter method to achieve the optimum value of them. The simulation results are obtained using CST software. And the proposed antenna is manufactured in the Electronic Manufacturing Center at the Ministry of Science and Technology, also the vital parameters are measured, a good agreement between simulation and measured results are achieved.
