US Patent 11881628 Adding virtual receive antennas using switching devices

Millimeter-wave (mmWave) and sub-mmWave technology, apparatuses, and methods that relate to receivers for wireless communications are described. The various aspects include an apparatus of a communication device including an antenna array and switching circuitry coupled to each antenna of the antenna array. The switching circuitry is configured to switch at a rate based on the center frequency of incoming communications on each respective antenna to generate at least two antenna patterns and provide the at least two antenna patterns to processing circuitry for decoding.
