Abstract :
This letter presents a novel wideband pattern reconfigurable antenna. The antenna consists of a pair of Vivaldi-shaped slots, two switches, and a rectangular slot for impedance matching. By switching between the on and off status, the proposed antenna is able to provide three different radiation patterns over a bandwidth from 4.96 to 8.3 GHz: one broadside mode and two oppositely directed endfire modes. We investigate the antenna´s impedance bandwidth, its radiation characteristics, and time-domain characteristics. Experimental and simulated results are presented and discussed.
