PROBLEM TO BE SOLVED: To provide a low-cost active phased array antenna and an antenna controller which are of simpler structure and capable of varying continuous antenna orientation characteristics. SOLUTION: This array antenna 200 has antenna patches 106a,..., 106p which are arrayed in matrix on a dielectric substrate at equal intervals in the row and columnar directions, a grounded feed terminal 108 which is applied with high-frequency electric power, a 1st control voltage generating means 111 which generates a row direction control voltage, and a 2nd control voltage generating means 112 which generates a column-directional control voltage. The antenna patches 106 are connected to the feed terminal 108 by feed lines 121, branching off from the feed terminal 108 respectively and phase shifters 107, are arranged constituting a part of the feed lines 121 in this array antenna.
