A relatively small phased array antenna is formed at a low cost even if the number of radiating elements increases in order to improve the gain. The phased array antenna has a multilayered structure in which a number of radiating elements (15), a phase shift unit (16) for changing the phase of an RF signal transmitted/received at each radiating element, and a distribution/synthesis unit (14) are formed on different layers. Signal lines (X1-Xm) and scanning lines (Y1-Yn) are wired on a phase control layer (35) to connect phase shift units to each other in a matrix. The signal lines and the scanning lines are matrix-driven by selection units (12X, 12Y) so that desired phase shift amounts are set to phase shift units located at the intersections of the signal and scanning lines. In addition, circuit portions repeatedly arranged in a single phase shift unit are formed into single chips mounted on another substrate.
