PROBLEM TO BE SOLVED: To provide a phased array antenna assembly which can eliminate making the circuit of the phased array antenna assembly complex. SOLUTION: The phased array antenna assembly 1 comprises a transmitter 60, and a plurality of passive phase shifter panels 70. The transmitter 60 has a control section 62, a modulator 63, a transmitting section 61, and a synthesizer 64. The passive phase shifter panel 70 has receiving antenna elements 19, transmission-type antenna elements 18 and phase shifter units 10 arranged, in an array form. The phased array antenna assembly 1 not only performs spatial power supplying of high-frequency signals transmitted by beam steering but also supplies the passive phase shifter panel 70 with the phase information on each phase shifter unit required for beam steering, and power supply power for driving each phase shifter.
