摘要：
A wideband frequency reconfigurable dielectric resonator antenna (DRA) is presented and discussed. The proposed antenna is capable of frequency switching at two different bands between 4.12 GHz and 8.85 GIz. The rectangular dielectric resonator with a permittivity of 15 is fed by U-shaped microstrip feed line. By setting the switch on the connecting lines of a network that feeds the dielectric element and changing the state of switch from ON to OFF, a shift of the well-matched DR operating frequency range is obtained. The total antenna dimensions are 40 x 45 x 4.5748 mm(3). The results indicate that the proposed antenna with acceptable performance provides two wideband modes with the impedance bandwidth of 49% and 25%.
