This paper describes a wideband dielectric resonator antenna with 30% fractional bandwidth, operating at 11GHz. The structure consists of a hollow cylindrical dielectric pellet fed by individually switched excitation probes. The switched excitation pattern provides the antenna a radiation beam that can be moved through 360 degrees in the azimuth plane. Simulation and experimental results are presented to illustrate the advantages of this design. © 2007 IEEE.
