Claim:
1. An array antenna device having a plurality of radiation elements, the array antenna device comprising: a dielectric substrate; two or more series array antennas formed on the dielectric substrate, the two or more series array antennas consisting of the plurality of radiation elements which are connected in series by conductor lines; a distributor formed in a layer different from a layer of the dielectric substrate where the series array antennas are formed, the distributor distributing power via capacitive coupling to the two or more series array antennas; and a phase adjuster adjusting a phase of power distributed by the distributor; wherein: the phase adjuster is adjusted relatively in a range of substantially reverse phase of −135 to −225 degrees including the distributor as a feeding phase condition to the two or more series array antennas.
