In the present endeavor a tunable (frequency agile) stacked slit loaded circular micro-strip antenna has been presented for wireless systems. The frequency agility has been achieved by loading a varactor diode. The antenna is able to operate in five bands. One of these bands hopes over different bands while others are fixed at 1.9611GHz, 2.1179GHz, 2.3018GHz and 2.6203GHz. The bands are useful for different wireless applications. The mathematical model presented here is very accurate and gives clear picture of facts happening in the antenna. Antenna parameters like return loss, resonant frequency, gain, directivity, co and cross polar patterns have been obtained from simulation and numerically.
