Abstract

An RF receiving/transmitting array is provided. The array includes an array of antenna elements, a number of phase detecting blocks that are each coupled to a respective pair of adjacent antenna elements, a phase shifter associated with each of the antenna elements, and a control circuit coupled with the phase detecting blocks and phase shifters. The controller receives information indicative of a phase difference between adjacent antenna elements of a received RF signal and outputs a signal to each phase shifter responsive to the phase difference. An RF transmitter may transmit RF signals from the array of antenna elements having one or more beams directed in the direction of RF signals received by the plurality of antenna elements.
