Review and survey of compact and broadband Microstrip Patch Antenna

Abstract

Microstrip Patch Antenna is generally used in modern communication devices. Study of past few year shows that, most of work on MPA is focused on designing compact sized Microstrip Antenna. As per Microstrip Patch Antenna offer low profile, low cost and low volume. Study of literature of past few year shows that, the leading work on MPA is focused on designing compact sized broadband microstrip antenna. But inherently MPA have narrow bandwidth so to enhance bandwidth various techniques are engaged. Today Communication devices support several applications which require higher bandwidth; such as mobile phones these days are getting thinner and smarter but many application supported by them require higher bandwidth, so microstrip antenna used for performing this operation should provide wider bandwidth as well as their size should be compact so that it should occupy less space while keeping the size of device as small as possible. In this paper a review of different techniques used for compact and broadband microstrip patch antenna is given.
