A heterogeneous dielectric resonator antenna (h-DRA) capable of beam steering is presented. It is been shown that the far-field radiation pattern of dielectric resonator antenna (DRA) can be redirected by manipulating the regional dielectric properties of the antenna. The physical antenna resonated at ˜ 1.2 GHz and measurements were in agreement with simulation. Although work was done using liquid dielectrics, this type of antenna will work equally well when fabricated from machined solid dielectrics. © 2008 Elsevier GmbH. All rights reserved.
