In modern communication devices, microstrip patch antennas are preferred to conventional antennas due to their size. In this review, a survey of commonly used techniques and designs for microstrip antennas is conducted. These techniques and designs were used by the authors to design an effective, low-profile, small, compatible, and affordable microstrip antenna. They were mostly used to design reconfigurable, multiband, and wideband antennas. After that, a initiator patch design with dimensions is provided on which technique will be used to analyze various antenna parameters. In recent years, research into microstrip patch antennas has made significant progress. Microstrip patch horns outperform conventional microstrip patches in a number of ways, including their low cost, ease of integration with integrated microwave circuits (MICs), low volume, small size, high performance, and low weight.
