Phased array antenna module

A phased array antenna module comprising:

• a plurality of antenna elements configured to perform any one or both of radiation of a transmission wave and capture of a reception wave;
• and
• a phase adjuster configured to set a beam direction of any one or both of the transmission wave and the reception wave by adjusting a phase of any one or both of a transmission signal supplied to each of the plurality of antenna elements and a reception signal output from each of the plurality of antenna elements, and to perform any one or both of setting of the transmission wave to a circularly polarized wave and setting for receiving the reception wave as the circularly polarized wave,
• wherein the phase adjuster includes a first phase adjuster and a second phase adjuster,
• a phase adjustment resolution of the first phase adjuster is smaller than a phase adjustment resolution of the second phase adjuster, and
• a mounting area of the first phase adjuster is larger than a mounting area of the second phase adjuster.
