  • Patent number: 10923818
    Abstract: Systems and methods which provide a hollow dielectric block dual-fed dual-frequency antenna configuration, such as may be utilized for wireless device communication in multiple RF bands, multi-frequency radar applications, etc., are described. Embodiments of a hollow dielectric block dual-fed dual-frequency antenna provide operation with respect to widely separated frequencies, such as to operate at frequencies in both a millimeter-wave band and a microwave band. A hollow dielectric block dual-fed dual-frequency antenna of embodiments of the invention may be fabricated from a single hollow dielectric block configured to integrate a dielectric resonator antenna (DRA) and a Fabry-Perot resonator antenna (FPRA), wherein the hollow dielectric block may be configured to serve as the resonator for the DRA and the superstrate for the FPRA simultaneously. The resonant frequencies of the DRA and FPRA of a hollow dielectric block dual-fed dual-frequency antenna of embodiments can be determined independently.
