Design of Flexible Antenna for UWB Wireless Applications Using ANN

This paper presents the design of UWB flexible wireless antenna for WLAN, 5G, and WiMAX applications. The design is a pentagonal shaped radiating element placed on top of flexible polyimide substrate and simulated using the wellknown 3-D electromagnetic (EM) simulator HFSS, v.18.1. As the EM simulator required large computing cluster to solve the design under consideration in addition to the time consumed, Artificial Neural Network (ANN) is used to implement the design and eliminate the factor of time and cost for the aforementioned structure. ANN with 1 hidden layer of 15 neurons based on Levenberg-Marquardt algorithm is presented. An error of less 6% is produced during the leaning, validation, and testing processes. The implemented ANN is a good candidate to represent the design and eliminate the factor of simulation time in addition to the cost of large computing cluster.
