The phased array antenna comprises a plurality of antenna elements arranged in a first direction and a second direction intersecting the first direction, a plurality of frequency mixers for respectively supplying transmission signals with a predetermined transmission frequency (f) to the plurality of antenna elements, and means for generating a plurality of first mixing signals having a predetermined first phase difference (Δφ) between the antenna elements adjacent to each other in the first direction and a plurality of second mixing signals having a predetermined second phase difference (Δφ) between the antenna elements adjacent to each other in the second direction, based on three frequency-controllable input signals with respective frequencies different from each other, and supplying the plurality of first mixing signals and the plurality of second mixing signals to the plurality of frequency mixers.",
