Mechanically steerable dielectric fluid antenna

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 ≈1.2GHz 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.
