摘要

A reconfigurable bandwidth antenna is proposed. A Vivaldi antenna is used in the design due to its wideband capability,moderate high gain and symmetrical radiation patterns in the E and H planes. To vary the frequency bandwidth of the Vivaldi, two pairs of resonator rings have been integrated along the elliptically shaped slot line. The resonator rings are deactivated or activated with the aid of switches to yield either a wideband frequency of 1-2.8GHz or two narrower frequencies with different bandwidths at 2.6GHz, respectively. This principle of bandwidth reconfigurability can be potentially put into use in OFDMA-related applications such as LTE since there are multiple sub-carriers which are aggregated based on the rate needs of the user at each instance ranging from 1.4 to 20MHz. The simulation results are obtained using CST microwave studio, and the results show good agreement with the measured results.
