Recent Review on Microstrip Patch Antenna for New Technologies

– In today’s modern communication, various technologies have been increased. It greatly rises the requirements of wireless communication channel with light weight antennas. The microstrip patch antenna with recent technologies are found to be suitable to fulfill these requirements of RF communication systems. Generally, Microstrip patch Antenna (MPA) comprises of substrate, patch and ground plane. It can be easily fabricated using printed circuit board (PCB) technology. It is also called as ‘Printed antenna’. Different feeding techniques like microstrip line, co-axial probe, aperture probe, aperture coupling, proximity coupling can be used as feed to the antenna. Several techniques have been used to improve the performance of the microstrip antenna. Still, the Microstrip Patch Antenna suffers from low gain, low efficiency and narrow bandwidth. Some of the commonly used techniques through which the performance of microstrip patch antenna can be enhanced are slotting, stacking, defected ground, shorting pins, metamaterial loading, etc. In this work, various techniques for designing a MPA were discussed. To understand the limitations of MPA, comparisons of the existing methods were carried out. This paper will serve a basic conceptual idea about MPA for the new researchers.
