Design and Optimization of Micro strip Patch Antenna for Satellite Applications

Abstract

Microstrip Patch Antenna for Ultra Wide Band 3.1 to 10.6 GHz is the subject of this thesis. Microstrip patch antenna fundamentals are the focus of this dissertation. The antenna's properties were studied parametrically to determine how their different geometrical and other factors affected them. The patch and ground plane size and separation, as well as the substrate material's dielectric constant, are among the antenna's geometrical characteristics. In order to get the best outcomes and performance, the parametric research also examines several strategies for optimising various antenna characteristics. This is a simulated experiment. CST microwave Studio simulation software is used to create the antenna design and simulation. The full UWB spectrum is covered by four antennas of varying forms and sizes. The first antenna design had two overlapping half-circular patches. Antenna performance is enhanced by cutting a small rectangular slot through the patch. The antenna's return loss curve indicates a bandwidth of 3 GHz to 12 GHz, with a low S11 of -45 dB at 3.5 GHz. elliptical patch antenna with modified ground plane, which spans 2.46 Ghz to 13.62 Ghz, has a minimal return loss at resonance frequency 10GHz of -50dB. The second design.
