In this paper, the authors present a novel design of simple partial ground plane Gap Coupled Rectangular Microstrip Antenna (GCRMA) for wideband operation. The radiating patch of antenna is splited into smaller parts along its width. By suitably gap coupling the splited elements, the triple band, dual band and single band operation can be achieved. The antenna operates from 1.45GHz to 5.65GHz and gives a maximum impedance bandwidth of 118% with a peak gain of 3.90dB, when the radiating patch is splited in to two parts and by placing the splited parasitic element gap coupled to the driven element with a gap of 0.1cm.
