In this paper present, compact, only feed, various frequency reconfigurable Micro strip patch switchable to inverted C- slot antenna is proposed. Firstly design a basic 3.64 GHz inset feed antenna. In this design, a inverted C-slot inserted on the square patch of the 3.64 GHz antenna and two copper strip switches (like Ideal Diode) are puts inverted C-slot. proposed antenna is competent of frequency switching at four different application like- 1.85 GHz Personal communication system (PCS), 2.3 GHz Telemetry Tracking and Control (TTC), 2.56GHz (WiMax technology), 2.84GHz(Air Traffic Control). Reproduced results are used to exhibit the presentation of the antenna.
