Abstract
An antenna receiver includes a plurality of mixers for frequency-converting signals received by a plurality of antennas into intermediate-frequency signals; a plurality of local oscillators, which correspond to the plurality of mixers and which supply local oscillation signals having the same frequency to the mixers; a plurality of PLL circuits, which correspond to the plurality of local oscillators and which set the frequency of the local oscillation signals; and an adder for adding the intermediate-frequency signals output from the mixers. The phases of reference signals supplied to the PLL circuits can be changed independently from each other.
