UWB Elliptical Patch Antenna with Partially Hexagonal Ground Plane

Abstract

Innovative methods for creating a partly hexagonal ground plane with an elliptical patch antenna for pulse transmission are presented in this research. The suggested ultra-wideband (UWB) antenna introduces a rectangular gap in the hexagonal ground plane and is fed by a microstrip line. When the voltage standing wave ratio (VSWR) is less than 2:1, the suggested antenna's simulated impedance bandwidth ranges from 3.2 GHz to 12.9 GHz. The simulation program CST Microwave Studio is used to analyze the antenna utilizing FR-4 substrate with a dielectric constant of 4.4 and a substrate thickness of 0.8 mm. In relation to -10 dB, the simulated findings have shown a fair return loss. The antenna's emission patterns at various frequencies are shown.
