Abstract:
A phased array antenna used to transmit/receive an RF signal such as a microwave and milliwave to adjust a beam direction by controlling a phase of the RF signal transmitted/received by each radiation element, characterized by comprisinga first multilayered structure made up of at least radiation element means on which a large number of radiation elements are arranged, and phase control means on which a large number of phase controllers for controlling the phase of the RF signal transmitted/received to/from each radiation element are mounted, wherein each phase controller includes a plurality of driver means for outputting control signals to give a predetermined phase shift amount for each radiating element and a plurality of phase shift means for receiving the control signals to control a phase of each radiating element, the phase shift means being simultaneously formed on a substrate of the phase control means, and the phase control means has an internal space having a predetermined height on an internal layer surface mounted with the phase controllers.
