Abstract: An array antenna apparatus includes: a wiring substrate having a plurality of fed patch antennas and a plurality of active element circuits electrically connected to the plurality of fed patch antennas, respectively; and a plurality of antenna substrates each having a parasitic patch antenna. The plurality of antenna substrates are joined onto one wiring substrate. Thereby, it becomes possible to provide an array antenna apparatus that can be reduced in size and has excellent antenna characteristics.
