Microstrip Antenna with Patch and Ground Plane Modification for Ultrawideband (UWB) Applications

Abstract

This invention concerns an Ultra-wideband (UWB) antenna that has been widely used for radio and radar telecommunications applications. Ultra-wideband (UWB) microstrip antennas have several advantages including relatively small dimensions, low transmit power, and easy fabrication. The purpose of this article is to determine the optimization of the performance of microstrip antennas with patch and ground plane modifications for Ultra-wideband (UWB) applications. The method used is electromagnetic computing. Based on the research conducted, with a rectangular patch design with triangular cuts and an L-shaped slot on the ground plane, an antenna capable of working at UWB frequencies was obtained. This UWB microstrip antenna has dimensions of 28 mm x 32 mm x 1.6 mm with fabrication using FR-4 substrate material with a dielectric constant (εr) = 4.3.The simulation results of a UWB microstrip antenna with a triangular section and L-slot on the ground plane show that the antenna can operate at UWB frequencies from 2.83 GHz to 10.92 GHz. The highest gain value is produced at a frequency of 9 GHz of 4.29 dBi with elliptical polarization and an omnidirectional radiation pattern.

Description
