The very first idea of microstrip antenna was given by G. A. Deschamps in
1953 [1]. However, it did not receive practical exposure until the 1970s and it was
further developed by Robert E. Menson [2]. The microstrip antennas are also called
patch antennas and abbreviated as MSA. The microstrip antenna has various key
advantages due to its low profile, light weight, low cost, and miniaturization capability
[3-4]. There are various authentic applications of microstrip antenna such as satellite
communication, Radar, WLAN, and WiMAX [5-9]. Nowadays, microstrip antennas
are widely used for military and civilian applications such as broadcast radio,
television, mobile systems, radio-frequency identification (RFID) system, vehicle
guidance system, a global positioning system (GPS), vehicle collision avoidance
system, multiple-input multiple-output (MIMO) systems, radar systems, determination
of direction, surveillance systems, biological imaging, and missile systems, etc.
