Abstract
A reconfigurable millimeter wave multibeam antenna array is disclosed. In an exemplary embodiment, an apparatus is provided that includes a first millimeter (MM) wave antenna, a second MM wave antenna, and a hybrid coupler coupled to the first and second MM wave antennas, the hybrid coupler configured to receive a MM wave transmit signal and a phase shifted version of the MM wave transmit signal, and to direct power to the first and second MM wave antennas based on a phase difference between the MM wave transmit signal and the phase shifted version of the MM wave transmit signal.
