A novel technique for obtaining a single-layer single-feed dual-band microstrip antenna loaded with narrow slots having capacitive loading has been studied which shows tuning and reconfigurability at the two frequencies 1.72GHz and 2.885GHz respectively. By embedding a pair of slots of proper lengths close to the radiating edges, the rectangular patch has been shown to realize dual-band broadside directions. More freedom for tuning the resonant frequencies, the frequency ratio and the input impedance are available because of more design parameters such as slot length and width and its position from radiating edges.
