PROBLEM TO BE SOLVED: To obtain a phased array antenna in which a higher harmonic wave is prevented from being generated by the non-linear effect of an amplifier when amplifying a macro wave input to the amplifier and radiated in a specific angle direction at high level. SOLUTION: A phased array antenna including a plurality of element antennas 1, amplifiers 8, 9 connected to the element antennas 1 and a phase shifter 6, wherein lengths of transmission lines connecting the element antennas 1 and the amplifiers 8, 9 are randomized.
