摘要： The antenna device includes: an element part 100 having an excitation element 1, a first passive element 11 having first and second conductive parts 11a and 11b, a second passive element 21 having third and fourth conductive parts 21a and 21b, a first switch 12 controlling conduction between the first and second conductive parts, and a second switch 22 controlling conduction between the third and fourth conductive parts; and a controller 200 outputting an electric signal for controlling conduction of the first and second switches. The controller outputs identical DC signal to the first and second switches, and one of the first and second switches is brought into conduction while the other one is brought out of conduction.

摘要： An array antenna device AAD including: a plurality of element antennas EAs; a transmission/reception module TRM, which is to be connected to one of the EAs, and includes a transmission circuit TC, a reception circuit RC, and a transmission/reception switch; a transmission/reception controller controlling by controlling an amplitude and phase of a signal passing through each TC and RC, and by switching transmission/reception; a distributor distributing a signal from a signal transmitter to each TC to transmit a distributed signal from the each TC; a combiner combining a signal from the each RC; and a receiver receiving the combined signal. A detection signal, which contains a detected amplitude and phase of the signal received by the receiver, is corrected with a piece of interconnection amplitude-phase information about the EAs to obtain a calibration value in calibration of each TRM, and calibration is conducted with the calibration value.

摘要： There are provided a communication excitation distribution calculating unit (11) that calculates an excitation distribution W1(t) of a communication beam using an excitation phase distribution S that directs a main lobe of the communication beam in a communication direction; an interference excitation distribution calculating unit (14) that calculates an excitation distribution W2(t) of an interference beam using an excitation phase distribution D that forms a null of an antenna pattern in the communication direction; and an excitation distribution combining unit (20) that combines the excitation distribution W1(t) of the communication beam and the excitation distribution W2(t) of the interference beam. An amplitude/phase controlling unit (30) controls amplitudes and phases of carrier signals to be provided to element antennas (3-1) to (3-K), in accordance with the combined excitation distribution obtained by the excitation distribution combining unit (20).

摘要： A signal combiner (33) specifies a weighting coefficient w for suppressing a grating lobe included in a composite signal S3 obtained when combining a digital received signal S1 and digital received signal S2 stored by a signal calculation storage (31), from the gain in a grating lobe direction in a first radiation pattern and the gain in a grating lobe direction in a second radiation pattern, and combines the digital received signal S1 and digital received signal S2 stored by the signal calculation storage (31) using the weighting coefficient w.
