Comparison of performance characteristics of rectangular, square and hexagonal microstrip patch antennas

The recent developments in the era of low-cost and compact communication systems have largely been due to the advent of small weight and size antennas that are capable of giving good output characteristics over a large frequency range. Microstrip patch antenna has become very famous and has attracted much attention towards the research because of these reasons. In this paper, the comparison of three widely popular designs of microstrip patch antennas has been done. Designing begins with the design of patches and then its analysis. Rectangular, square and hexagonal micro strip patch antennas are analyzed using HFSS and a comparison is made between them. In addition to low computational complexity, enhanced connectivity and high speed, modern wireless communication networks also offer advantages such as low profile structures, lightweight, gain must be high and compact size that assures reliability, mobility, and good efficiency. The compact design of patch antennas is due to conventional micro-strip fabrication technique.
