    Abstract: PROBLEM TO BE SOLVED: To utilize small, narrow-band and frequency adaptable antennas to provide coverage to a wide range of a wireless modem and frequency bands on a host wireless device.SOLUTION: Transmit and receive antennas 302, 303 have narrow pass-band characteristics, require minimal space on a host device, and allow smaller form factor. The frequency tunability further allows a fewer number of transmit and receive antennas 302, 303 to be used. The operation of the transmit and receive antennas 302, 303 may also be adaptably relocated from an unused modem to an in-use modem to maximize performance. These features of the antennas result in cost and size reductions. In another aspect, the antennas may be broadband antennas.

    Abstract: PROBLEM TO BE SOLVED: To provide a way to perform point-to-multipoint transmission using an adaptive or directional antenna while reducing an antenna array pattern distortion.
    SOLUTION: Generally, rather than transmitting a same waveform to two or more receivers, an information bearing signal is transformed into different decorrelated waveforms and each decorrelated waveform is transmitted to a different receiver. In one implementation, an information bearing signal is transformed into two decorrelated signals S
    1 (t), S
    2 (t), such that their cross-correlation or auto-correlation of the information bearing signal, is zero or very small. Such decorrelation may be achieved by sending a first signal to a first receiver 104, while sending a second signal with a radio frequency spectrum that is the spectrally inverted version of the first signal to a second receiver 106. In another implementation, a first signal is transmitted to the first receiver 104, and is also transmitted to the second receiver 106 with a time delay.

    Abstract: A dielectric resonator antenna (100) having a resonator (104) formed from a dielectric material mounted on a ground plane (108). The ground plane (108) is formed from a conductive material. First and second probes (112, 116) are electrically coupled to the resonator (104) for providing first and second signals, respectively, to or receiving 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 connected to the perimeter of the resonator (104) and are substantially orthogonal with respect to the ground plane (108). The first and second signals have equal amplitude, but 90 degrees phase difference with respect to each other, to produce a circularly polarised radiation pattern. A dual band antenna (200, 220) can be constructed by positioning and connecting 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.
