More Information
Summary:A main antenna arrangement is configured to receive with a pre-configured first directional radiation pattern having a first beam with a first beamwidth and to provide first received signals at a first output, and at least one auxiliary antenna is configured to receive with a pre-configured respective second directional radiation pattern having a second beam with a second beamwidth, different from the first beamwidth and to provide second received signals at a second output. Interference cancelling circuitry is configured to control the amplitude and phase of the second received signals received from the at least one auxiliary antenna to produce weighted second received signals and combine the weighted second received signals with the first signals received from the main antenna arrangement to reduce a level of interference signals received by the main antenna arrangement in relation to a level of wanted signals received in the main antenna arrangement.
