Design and Optimization of a Multiband Extra Wideband Ring Patch Antenna for 5G mm-Wave Communication at 28/60/80 GHz Using MLPNN based K-fold cross validation method

Abstract

In this paper, we present the design of an innovative Ultra-Wideband (UWB) ring patch antenna customized for 28 GHz, 60 GHz and 80 GHz and 5G mm-Wave communication. The antenna features a ring patch with an embedded small rectangular patch and a partial ground plane. To optimize the antenna dimensions for resonance at 28 GHz, 60 GHz, and 80 GHz, a Multilayer Perceptron Neural Network (MLPNN) was employed with a k-fold cross-validation technique. Simulation results demonstrate that the MLPNN-optimized antenna achieves superior performance metrics, including a low reflection coefficient, efficient radiation patterns, and a wide bandwidth of 13.2 GHz at 28 GHz and an extended bandwidth of 53 GHz spanning from 47 GHz to 100 GHz. These characteristics highlight its potential as a robust solution for next-generation 5G communication systems.
