Patch with Rectangular Slit

Abstract

This paper presents an enhancement in performance of a patch antenna using Slit structure. The Slit structure is applied to improve the antenna again. The antenna design is developed using HFSS (High Frequency Structure Simulator) software. Initially, a reference model is developed using single patch antenna. In simulation, this reference The antenna functions at a frequencyof2.45GHz,with again of 2.92dB, a band width of218MHz, and a VSWR of 1.58. To improve the antenna's gain the Slit structure is incorporated. The simulation of this modified antenna shows that it operates at the same frequencyof2.45GHzbutwith againof3.03dB,a bandwidth of 233 MHz, and a VSWR of 1.32 Consequently, the gain is improved from 2.92dB to 3.031dBbyemployingtheSlit structure.
