Abstract

Systems and methods which provide filtering dielectric resonator antenna (FDRA) configurations implementing radiation cancellation are disclosed. Embodiments of a FDRA provide implementations of dielectric resonator antennas (DRAs) which are configured with a loop feed structure facilitates radiation cancellation to provide radiation nulls at frequencies outside of a desired passband to thereby implement radiation cancellation for filtering functionality of the FDRA. FDRAs of embodiments may be variously polarized, such as to provide linear polarization or circular polarization.
