Abstract
An array antenna is provided with: a first conductive member including a planar part; plural antennas arranged at a predetermined first interval to the planar part of the first conductive member, each of the plural antennas transmitting and receiving radio frequencies of a first polarization and radio frequencies of a second polarization that is different from the first polarization; and a second conductive member provided between the antennas adjacent to each other among the plural antennas via a gap of a predetermined second interval to the planar part of the first conductive member, the second conductive member being capacitively coupled to the first conductive member.
