Abstract: The advantageous radiation characteristics, low cost, lightweight design, ease of production and analysis, and affordability of microstrip patch antennas have contributed to their recent surge in popularity. Patch antennas provide a lot of advantages, but they also have certain drawbacks, such as a limited bandwidth, weak gain, and the potential to modify and reduce radiation patterns. In this paper, a circular and rectangular microstrip patch antenna design, modelling, and analysis are provided. The performance of the antennas is discussed in relation to the bandwidth, front-to-back ratio, 3D radiation pattern, reflection loss, and reflection factor coefficient at the inlet. Resonant antenna designs are required, and they are constructed on FR-4 substrates with a thickness of 0.71 mm and a permittivity ratio (εr) of 10, fed by a 50 Ω microstrip feed line. With a gain of 6.37dBi, the rectangular patch antenna operated at 0.17GHz in bandwidth. The 6.53dBi and 0.16GHz bandwidths are displayed simultaneously by the circle patch antenna. Based on a comparative analysis of their respective performances, the rectangular antenna performs better in terms of bandwidth than the circular antenna. Circulars are superior to rectangular at achieving good matching, even if circulars have better profits. As such, applications requiring fixed end-to-end communications may find the antennas to be a perfect solution. microstrip feedline arrangement. Sugandha’s et al.
