Patent number: 8630581Abstract: A repeater and associated method of use includes at least one antenna element for communicating in one direction and at least one antenna element for communicating in another direction. A radio frequency uplink path and a radio frequency downlink path are coupled between the antennas. At least one of the radio frequency uplink path or the radio frequency downlink path includes an adaptive cancellation circuit. The adaptive cancellation circuit is configured to generate a cancellation signal without requiring an injected signal. The cancellation signal, when added to a radio frequency signal in the respective uplink and downlink paths, substantially reduces feedback signals present in the radio frequency signal.Type: GrantFiled: January 18, 2013Date of Patent: January 14, 2014Assignee: Andrew LLCInventors: Mano D.

Patent number: 7577398Abstract: A flat-panel repeater includes a housing having a pair of oppositely facing surfaces, at least one antenna element mounted to each of the surfaces for radiating energy in a direction opposite to that of an antenna element mounted to the other of the surfaces, and an electronic circuit mounted within the housing and operatively coupling signals between at least one antenna element on each of the oppositely facing surfaces of the module. Isolation between the antennas on opposite sides of the repeater is improved by various techniques, such as use of adaptive cancellation which removes a significant portion of the feedback signal power, therefore increasing the total system isolation by the same amount. This additional isolation can be used to achieve greater system gain, and therefore significantly extend the range of the system.Type: GrantFiled: January 16, 2001Date of Patent: August 18, 2009Assignee: Andrew LLCInventors: Mano D.

Patent number: 6934511Abstract: An integrated repeater includes a housing having opposing sides, a donor antenna mounted on one of the opposing sides, a null antenna mounted on the other of the opposing sides, and repeater electronics mounted in the housing and operatively interconnecting the donor antenna and the null antenna. The repeater electronics include a beamforming arrangement for creating a desired antenna pattern of the donor antenna relative to a base station and a desired antenna pattern of the null antenna relative to subscriber equipment, and interference cancellation electronics for cancelling interference feedback signals between the donor antenna and the null antenna in both an uplink path and a downlink path.Type: GrantFiled: October 23, 2000Date of Patent: August 23, 2005Assignee: Andrew CorporationInventors: Breck W.

Patent number: 6615021Abstract: A repeater for transmitting and receiving radio frequency (RF) signals to and from a pager. The repeater includes a forward path for receiving a first RF signal from a base station and a reverse path for receiving a pager signal from a pager. The forward path includes a channelizer which down converts the first RF signal to an intermediate frequency (IF) signal, amplifies the IF signal, and up converts the IF signal to a second RF signal suitable for transmission to a pager. The reverse path includes a second amplifier which amplifies the pager signal to an amplified signal suitable for transmission to a base station antenna.Type: GrantFiled: November 2, 1999Date of Patent: September 2, 2003Assignee: Andrew CorporationInventors: Breck W.

Patent number: 6445904Abstract: A repeater diversity system includes a null antenna having a given phase center and polarization for receiving a communications signal from a remote signal source, a donor antenna for transmitting a signal to a base station, and a diversity null antenna having the same phase center as the receive null antenna and a polarization orthogonal to the polarization of the main null antenna. A combining network is coupled to the main null antenna and the diversity null antenna for combining the signals therefrom and an uplink channel module is coupled with the combining network for delivering diversity combined receive signals to the donor antenna.Type: GrantFiled: February 17, 2000Date of Patent: September 3, 2002Assignee: Andrew CorporationInventors: Breck W.
