Design of Dual Band Slot Loaded Rectangular Microstrip Antenna for Global Positioning Satellite

This paper presents an experimental investigation of inclined slot loaded rectangular micro strip antenna that has been carried out for dual -band operation with the help of a single probe feed for Global Positioning Satellite (GPS) applications. In this case, two resonant frequencies 1.57 GHz and 1.22 GHZ occur. It is observed that the VSWR and RETURN LOSS of two resonant frequencies can be changes by inclination angle of the slot. The design of this antenna is being simulated in IE3D software.
