    Abstract: A repeater for a wireless network in which a signal radiation path provided by building wiring is used to provide spatial separation between at least two radiating points. The repeater is preferably packaged into a housing that is suitable for use as an Alternating Current-to-Direct Current (AC/DC) transformer (or wall wart). If the radiating point includes at least one antenna, the antenna may also be incorporated within the transformer housing. The radiating points can be are provided by at least two antennas, in which case the building wiring includes a coaxial cable, such for carrying video or cable signals. The building wiring may also be standard Alternating Current (AC) three wire conductor cable which may or may not be placed within building walls. In this implementation, the radiating point is determined by a matching circuit. A frequency conversion circuit can cause the radiation from at least one radiating point to occur at a carrier frequency that is different from the carrier frequency of the other radiating point.

    Abstract: A directive antenna operable in multiple frequency bands includes an active antenna element and at least one passive antenna element parasitically coupled to the active antenna element. The passive antenna element(s) have length and spacing substantially optimized to operate at (i) a fundamental frequency associated with the active antenna element and (ii) a higher resonant frequency related to the fundamental frequency. Spatial-harmonic current-distributions of the passive antenna elements are used to create the multiple frequency bands of operation. The directive antenna also includes devices operatively coupled to the passive antenna element(s) to steer an antenna beam formed by applying a signal at the fundamental resonant frequency, higher resonant frequency, or both to the active antenna element to operate in the multiple frequency bands.

    Abstract: A repeater that extends the range of a wireless communication system especially one using Time Division Duplex (TDD) protocols. The device preferably translates signals received on a first radio frequency channel to a second radio frequency channel. The repeater preferably monitors one or more channels for transmissions. When a transmission on one channel is detected, the repeater is configured to translate the received signal to another channel where it is then transmitted. The device thus solves a problem of isolating input and output signal from one another.

    Abstract: An antenna assembly includes at least two active or main radiating omni-directional antenna elements arranged with at least one beam control or passive antenna element used as a reflector. The beam control antenna element(s) may have multiple reactance elements that can electrically terminate it to adjust the input or output beam pattern(s) produced by the combination of the active antenna elements and the beam control antenna element(s). More specifically, the beam control antenna element(s) may be coupled to different terminating reactances to change beam characteristics, such as the directivity and angular beamwidth. Processing may be employed to select which terminating reactance to use. Consequently, the radiator pattern of the antenna can be more easily directed towards a specific target receiver/transmitter, reduce signal-to-noise interference levels, and/or increase gain by using Radio Frequency (RF), Intermediate Frequency (IF), or baseband processing. A Multiple-Input, Multiple-Output (MIMO) processing technique may be employed to operate the antenna assembly with simultaneous beam patterns.
