Now days antenna designers are paying more attention on microstrip patch antennas, due to its numerous blessings in field of communication, inclusive of high reliability, light weight, ease of fabrication etc. but despite of its extreme benefits, patch antennas additionally experience some drawbacks viz low gain and narrow bandwidth. These drawbacks may be overcome by looking after a few parameters within the layout of antennas. there are various designing factors affecting the radiating traits of antenna together with patch dimensions, feeding techniques, substrate used in production of antenna etc. The paper is targeted on various bandwidth enhancement strategies. The paper accommodates of a short examine in feeding techniques, parasitic patch elements, advent of slots, twin feed, shorting pin, air hole, defective ground and so forth that enhances the bandwidth of antenna.
