Modeling elliptical slot antenna in the program high frequency system simulator

Abstract

This article presents the results of modeling an elliptical slot antenna in the software High Frequency System Simulator (HFSS). It was investigated the dependence the characteristics of the antenna on the change in thickness of the substrate. For research as substrate material is selected the dielectric with permittivity ? = 3, thickness of 1.575 mm, 2 mm, 3 mm. The results are presented in the graphs: the standing wave ratio (SWR), polar pattern, input impedance. It shows the structure of the antenna with the description of its parts. The regularities of changes in the characteristics of the elliptic slot antenna according to the variations of dielectric thickness are identified. Recommendations are given for the development of ultra-wideband antennas used in selecting the thickness of the dielectric. The results can be used to construct broadband antennas in telecommunication systems.
