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, low cost, 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 partial
removal of substrates.
