    Abstract: A dielectric resonator an-tenna (100) having a resonator (104) formed from a dielectric material mounted on a ground plane (108). The ground plane (108) is formed from a conduc-tive material. First and second probes (112, 116) are electrically coupled to the resonator (104) for providing first and second sig-nals, respectively, to or receiv-ing from the resonator (104). The first and second probes (112, 166) are spaced apart from each other. The first and second probes (112, 116) are formed of conductive strips that are electrically con-nected to the perimeter of the resonator (104) and are substan-tially orthogonal with respect to the ground plane (108). The first and second signals have equal am-plitude, but 90 degrees phase dif-ference with respect to each other, to produce a circularly polarised radiation pattern. A dual band antenna (200, 220) can be con-structed by positioning and con-necting two dielectric resonator antennas (204, 208; 224, 228) together. Each resonator (204, 208; 224, 228) in the dual band configuration (200, 220) resonates at a particular frequency, thereby providing dual band operation. The resonators (204, 208; 224, 228) can be positioned either side by side or vertically relative to each other.

    Abstract: A selectively coupled two-piece antenna for use in a mobile phone having a casing and radio frequency (RF) communications circuitry includes a composite radiator that is selectively extendable from and retractable into the casing and a communications interface that is connected to the RF communications circuitry. The composite radiator has first and second radiating elements, and a connecting element. When the composite radiator is extended, the connecting element connects the first and second radiating elements. In this position, the communications interface connects the RF communications circuitry to the first and second radiating elements. Thus, the RF communications circuitry transmits and/or receives RF signals through both the first and second radiating elements as a top loaded antenna. However, when the composite radiator is retracted, the connecting element electrically isolates the first and second radiating elements.

    Abstract: The balanced, retractable dipole antenna comprises a first radiator element that is selectively extendable from, and retractable into, a mobile phone casing, a second radiator element, and a counterpoise that is electrically isolated from a printed wire board (PWB) of a mobile phone. The balanced, retractable dipole antenna further comprises a signal balancing means coupled between a signal source and at least the second radiator element and counterpoise to generate first and second signals, respectively. The first and second signals are substantially equal in magnitude but out of phase by 180 degrees. When the first radiator is extended, the first signal is transferred to the first and second radiator elements, and the second signal is transferred to the counterpoise. When the first radiator element is retracted, the first signal is transferred to the second radiator, while the second signal is transferred to the counterpoise and the first radiator element. The first and second signals produce balanced currents, thereby producing a symmetric radiation pattern.

    Abstract: A system and method for automatically directing a communication antenna to point to a desired wireless communication transceiver, is presented herein. The system includes a position location receiver, which receives signals indicating the position location information of the antenna and a position location transmitter and a processing mechanism, which determines calibration information of the antenna. The calibration information is achieved by first establishing a reference vector between the location of the antenna and position location transmitter and establishing a vector reference space and then calculate the necessary elevation and azimuthal components, within the vector reference space, to identify the proper calibration of the antenna. Once the calibration information has been determined, an alignment mechanism automatically orients the antenna. The alignment mechanism then automatically directs the oriented antenna to point to the wireless transceiver, based on the directional location information of the wireless transceiver.
