A compact rectangular dielectric resonator antenna for UWB wireless communication systems

A compact rectangular dielectric resonator antenna (DRA) is presented for ultra wide band communication systems. Ansoft HFSS 3D electromagnetic solver is used for the design optimization and measurement results are also provided. The proposed antenna has a low profile (∼3), a small size, and a low permittivity constant (10.2). An impedance bandwidth about 46% (from 6.9 to 11 GHz) was achieved making this antenna suitable for UWB applications. © 2009 Wiley Periodicals, Inc.
