Abstract
A frequency reconfigurable wide slot antenna is presented. The proposed antenna is capable of switching the frequency bands between 1.3 and 2.7 GHz. The antenna has an overall dimension of 70mm × 70mm × 1.6mm, with a wide slot printed on one side of the substrate (RT Duroid5880, εr=2.2). A 50 Ω microstrip line printed on other side of the substrate is used to feed the slot. The antenna resonates at different frequency bands depending upon the feed line length. Hence the frequency re-configurability is achieved by varying the length of the feed line. When the length of the feed line is 30mm antenna resonates at 2.5GHz with an impedance bandwidth of 16% (2.25-2.65 GHz). For the feed line length of 40mm antenna resonates at 1.4GHz with an impedance bandwidth of 22% (1.31-1.62GHz). When the feed line length is changed to 60mm antenna resonates at 2.65GHz with an impedance bandwidth of 3% (2.61-2.69 GHz). The simulated and measured return loss and radiation pattern results for the proposed antenna are presented.
