In this paper, we published a survey and analysis on a variety of the various strategies for maximizing gain and bandwidth. Because of their low profile, light weight, lowcost, compactness etc., Microstrip Patch Antenna (MPA) is widely used in various antenna systems. Owing to its versatility, the patch antenna is often used with the Microwave IC and Monolithic Microwave IC's. But MPA’s lower gain and bandwidth is one of the key disadvantages. The researchers used various methods to achieve enrichment, such as in the microstrip antenna array, superstrate structure, change of dielectric material and partialremoval of substrates.
