Comparative Analysis of H -Shaped and F Shaped Microstrip Patch Antenna for Reduced Return Loss

The objective of this analysis is to create an H-shaped rectangular microstrip patch antenna using FR4 epoxy as dielectric material at a frequency range of 2.5 GHz so as to optimise the Return loss (dB) by using a High-Frequency Structure Simulator (HFSS) compared to a rectangular microstrip patch antenna with a F shape. A substrate has been included in the design of the rectangular patch antenna of FR4 epoxy substrate with a 4.4 dielectric constant and a thickness of 1.6mm. The sample size of H shaped and T shaped rectangular patch antennas is taken as 10 for each design. The total size is 40 with 80 % as pretest power. By varying both Hand F shape, the return loss was calculated. The rectangular microstrip H shape patch antenna achieved a return loss of -15.0845dB. The design is significantly better as the p value is less than 0.05. The return loss of H shaped shows better performance compared with rectangular microstrip patch antenna in the form of a F shape.
