Analysis on microstrip patch antennas for wireless communication

Microstrip patch antennas are the most one used for wireless communication. Its main characteristics are narrow in bandwidth, feasibility in cost, fabrication is easier. This paper describes about the analysis in different type of microstrip patch antennas with different frequency band. A dual frequency microstrip patch antenna, Star shaped patch antenna, E-shaped patch antenna, Octagonal shaped patch antenna are taken into account has been used in various wireless communication. Sometimes, the patch antennas are called UWB antenna if the same covers wide range of frequencies.
