In this paper, the authors present a frequency reconfigurable inverted circular patch antenna with U-slot. The incorporation of U-slot in the circular patch provides a wide impedance bandwidth than conventional patch antenna. By introducing shorts at appropriate position on U-slot and on feed, antenna can be made resonant at two frequency bands (1.80GHz-1.98GHz) and (2.10GHz-2.68GHz) in two modes. The proposed antenna not only avoid the interference problem faced in fixed dual band antenna but at the same time provides a good gain of nearly 8 dB in both mode of operation.
