Abstract :
A multilayer rectangular dielectric resonator antenna (DRA) operating at a new hybrid mode is presented. The DRA is formed by a dispersion engineered combination of isotropic/anisotropic dielectric layers. These layers are optimized to operate at a degenerate band edge (DBE) mode with the introduction of misaligned anisotropic layers. A prototype DBE-DRA antenna is realized by emulating the anisotropic medium with a periodic assembly of two-tone dielectrics (barium-titanate and alumina).
