A Survey on Microstrip Patch Antenna Using Shape of Patch Antenna

Antennas have a big role in wireless communications. Patch Antenna is very significant role in wireless communication, due to its simple characteristics, many applications in communications need very broadband bandwidth, but the narrow bandwidth of a microstrip antenna is one of the most important features that restrict its wide usage. Therefore the main motto of this paper is to increase the bandwidth of microstrip antenna by using various bandwidth increasing techniques. So to enhance the bandwidth and overcome this difficulty we have design different shape patch antenna such as Microstrip Stacked patch antenna, S-shaped patch antenna, Y-shaped patch antenna and W-slotted patch antenna and concluded that Microstrip Stacked patch antenna presents improved bandwidth at centre frequency of 2.4GHz,which is over 15% for │S₁₁│≤10 dB ranging from 2.314 to 2.677GHz rather than other microstrip Patch Antenna.
