Abstract
Apparatus and methods for beamforming communication systems with sensor aided beam management are provided. In certain embodiments, a beamforming communication system includes an antenna array including a plurality of antenna elements. The beamforming communication system further includes a plurality of signal conditioning circuits operatively associated with the antenna elements, one or more sensors that generate sensor data, and a beam management circuit that controls the signal conditioning circuits to manage beamforming. The beam management circuit provides beam management based on the sensor data.

A mobile device comprising:
- a laminated substrate;
- a first antenna array including a plurality of antenna elements arranged in an array of at least four elements by at least four elements on a first side of the substrate;
- a first sensor, the first sensor being a tactile sensor configured to generate sensor data in response to a user touching a touch screen of the mobile device;
- an integrated circuit die supported on a second side of the substrate opposite the first side and including signal conditioning circuitry electrically connected to the first antenna array and configured to condition a plurality of radio frequency signals each transmitted by a corresponding one of the plurality of antenna elements to thereby form a transmit beam;
- and
- a beam management circuit configured to, based on the sensor data generated by the tactile sensor in response to the user touching the surface of the mobile device, predict an environmental blockage based on an anticipated finger swipe movement and control the signal conditioning circuitry to manage the transmit beam formed by the plurality of antenna elements of the first antenna array, and to adjust an angle of the transmit beam based on at least a transmit signal fundamental frequency and distance between antenna elements in the plurality of antenna elements, the beam management circuit further configured to process the sensor data to move the transmit beam away from the environmental blockage predicted based on the anticipated finger swipe.
