Dielectric Resonator Antennas (Antennas Series) (Antennas)

The use of a dielectric resonator as a resonant antenna was proposed in 1983. Due to the absence of metallic loss, the dielectric resonator antenna (DRA) is highly efficient when operated at millimetre wave frequencies. With the use of high dielectric constant material, the DRA can also be used as a small and low profile antenna when operated at low microwave frequencies. Low cost dielectric materials are now easily available commercially: encouraging more antenna engineers to design communicati
