ARRAY ANTENNA DEVICE, ANTENNA MEASURING DEVICE, AND PHASE ADJUSTMENT METHOD AND PHASE ADJUSTMENT CONTROL DEVICE FOR ARRAY ANTENNA

摘要

To perform calibration so that respective element antennas have the same phase standards without letting all the element antennas radiate radio waves simultaneously.SOLUTION: A plurality of element antennas 1 are divided into element antenna groups 10, and operation element antenna sets 20 including at least two element antenna groups 10 including an element antenna group 10 having been measured are placed in operation one after another so as to radiate radio waves within a range of permissible radiation electric power values. A phase adjustment control device comprises: an element electric field computing circuit 11 which varies phases of element antennas 1, and use a plurality of received electric power values of radio waves radiated with different phases so as to calculates an in-set phase difference, in an operation element antenna set 20, of an element electric field vector that an element antenna 1 varying the phase generates; and a phase difference calculation part 16 which uses the element electric field vector of the element antenna 1 for which the element electric field vector is calculated using a plurality of different operation element antenna sets 20 to calculate phase differences of element electric field vectors of element antennas 1 belonging to different operation element antenna sets 20.SELECTED DRAWING: Figure 2
