1. An antenna module comprising:
a plurality of segments each including one input-output port and a plurality of antenna ports and each configured to amplify a radio-frequency signal; and
a plurality of subarray antennas each including a plurality of circularly polarized antenna elements, wherein
each of the plurality of circularly polarized antenna elements is connected to any of the plurality of antenna ports,
the plurality of circularly polarized antenna elements included in each of the plurality of subarray antennas constitutes a sequential array for each subarray antenna,
each of the plurality of segments includes
a distribution-combination circuit configured to distribute a signal that is input to a first port of the distribution-combination circuit to the plurality of antenna ports via a plurality of second ports of the distribution-combination circuit and configured to combine signals input to the respective plurality of antenna ports so as to output a combined signal from the first port, and
a first amplifier connected between the one input-output port and the first port, and a plurality of second amplifiers, at least one of the plurality of second amplifiers disposed along a signal flow path between one of the plurality of antenna ports and a corresponding one of the plurality of second ports of the distribution-combination circuit,
wherein, in any one subarray antenna of the plurality of subarray antennas, the plurality of antenna ports to which the respective plurality of circularly polarized antenna elements included in one subarray antenna are connected are included in one segment.
