Phased array antenna, transmitter, wireless power transmission system and wireless communication system

摘要

Problem to be solved: to provide a two-dimensional phased array antenna having a simple structure capable of reducing the number of control systems of the phase control of the antenna element and the number of control input ports.Phased array antennaA plurality of antenna elements arranged in a second direction crossing the first and first directionsA plurality of frequency mixers supplying a transmit signal of a predetermined transmission frequency (f) to each of the plurality of antenna elementsBased on the three input signals of frequency controllable mutually different frequenciesA predetermined first phase difference between adjacent antenna elements in the first direction Δφ A plurality of first mixed signals having 1 andA predetermined second phase difference between adjacent antenna elements in the second direction Δφ 2) generate a plurality of second mixed signals having aMeans for supplying said plurality of first mixed signals and said plurality of second mixed signals to said plurality of frequency mixers.Diagram
