A compact rectangular UWB Dielectric resonator antenna

A compact rectangular Dielectric resonator antenna (DRA) is presented for ultra wide band communication systems. Ansoft HFSS 3-D electromagnetic solver is used for the design optimization. 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 DS-UWB high band (i.e. 6 to 10.1 GHz) applications.
