Performance Comparison of Bow-Tie and Slot Antenna Based on RWG Edge Elements

Abstract

One of the most convenient way of analyzing antenna parameters using Rao-Wilton-Glisson (RWG) edge elements where the antenna surface is divided into a two dimensional array of very small triangle of alternately charged in continuous fashion. In this paper, the concept of RWG edge elements and method of moment (MoM) have been explored to determine distribution of surface current density, profile of magnetic field intensity and current density along the horizontal dimension of the antenna. In this paper, we have made a comparison between bow-tie and slot antennas in selecting appropriate antenna for a particular wireless link based on RWG edge elements.
