Abstract
The present disclosure provides a planar array antenna. The planar array antenna includes a plurality of phase modulation surfaces, in which each phase modulation surface includes an array including a plurality of transmission phase-shift elements; and a planar power source, configured to power the plurality of phase modulation surfaces, in which each phase modulation surface is configured to modulate a transmission phase of an electromagnetic wave based on the plurality of transmission phase-shift elements, and the plurality of phase modulation surfaces are controlled to change a relative position to change the beam angle based on the corresponding transmission phases. The planar array antenna may be installed in a conformal manner on surfaces of the mobile device, such as a vehicle, an aircraft, a ship or the like.
