    摘要： Dielectric resonator antennas suitable for use in compact radiofrequency (RF) antennas and devices, and methods of fabrication thereof. Described are dielectric resonator antennas fabricated using polymer-based materials, such as those commonly used in lithographic fabrication of integrated circuits and microsystems. Accordingly, lithographic fabrication techniques can be employed in fabrication. The polymer-based dielectric resonator antennas can be excited using tall metal vertical structures, which are also fabricated using techniques adapted from integrated circuit and microsystems fabrication.

    摘要： An elliptically polarized (EP) dielectric block antenna comprises a linearly polarized (LP) dielectric block antenna and a wave polarizer integrated with the LP dielectric block antenna. The wave polarizer converts the LP wave of the LP dielectric block antenna into an EP wave or a circularly polarized (CP) wave. The wave polarizer is directly integrated with the LP dielectric block antenna by fabricating inclined slots on faces of the dielectric block at an oblique angle to the LP wave direction of polarization. This provides a very compact EP or CP antenna with a broadside or omnidirectional radiation pattern. The EP or CP antenna is excited by an inner conductor of a SubMiniature version A (SMA) connector that can be directly connected to a coaxial line thereby providing a simple feed network for the antenna.

    摘要： The present invention is directed to a fuze application capable of GPS (Global Positioning System) and proximity radar functionality by co-locating a proximity radar antenna with a GPS DRA (Dielectric Resonator Antenna) fuze. The GPS DRA fuze has a HE11δ mode structure resulting in an E-field null at the center. The monopole proximity radar antenna is mounted in the E-field null center and is thus electrically isolated from the GPS DRA fuze. The high dielectric constant permits the GPS DRA fuze to operate in the L1 frequency and the electrically shortened proximity radar antenna to resonate in the C-Band within a small form factor. The GPS DRA fuze maintains a forward-looking CP (circular polarization) pattern while proximity antenna maintains a desirable monopole pattern. Nesting allows mounting of both GPS and proximity radar antennas on the fuze nose while reducing the total space occupied.
