            Abstract : 
The operating frequency of a coplanar patch antenna is tuned using a varactor mounted at one of the radiating edges. The coplanar patch antenna is tunable from 4.92 GHz at 0 V to 5.40 GHz at 19.5 V with a return loss better than 14 dB in this frequency range. The antenna provides a return loss better than 32 dB in the tunable frequency range of 5.16 to 5.40 GHz.
