Amplifying Antenna Performance: Techniques for Gain Enhancement in Microstrip Patch Array Antennas

Md. Motahar Hossain, Dr. Hossain K A

Abstract: In the contemporary landscape of communication systems, Microstrip Patch Antennas (MPAs) have gained immense popularity owing to their low profile, light weight, compactness, cost-effectiveness, and fabrication simplicity. In high-performance aircraft, spacecraft, satellite, and missile applications, where size, weight, cost, performance, ease of installation, and aerodynamic profile are constraints and low-profile microstrip antennas may be potent candidate. Despite their widespread use, MPAs exhibit a notable drawback in the form of low gain response. Researchers are actively engaged in overcoming this limitation, exploring diverse techniques to enhance MPA performance for specific applications. High gain antennas are particularly desirable in practical scenarios, providing extended coverage compared to their low gain counterparts. Microstrip array antennas emerge as promising candidates for achieving high gain, leveraging multiple radiating elements on a single substrate for versatile wireless applications. This paper delves into the background and current state of the problem surrounding MPA gain limitations. Various strategies reported in the literature to address these limitations include the use of parasitic patches, thick substrates, multi- resonator techniques, conventional array techniques, large ground planes, and stacked patches. However, each technique presents its own set of drawbacks, such as increased antenna size, complexity in multilayer fabrication, and additional impedance matching circuit requirements. Notably, conventional array antennas necessitate impedance matching circuits and transmission lines for connecting array elements, leading to bulkiness and increased internal losses, thereby compromising efficiency. The results of this study should greatly advance the field of micro strip antenna technology, creating new opportunities for useful and effective wireless communication systems. The 4x2 and 2x2 microstrip patch antennas developed in th
