Abstract: An embodiment of the present invention includes a signal processing device; a (1-1)-th antenna which transmits or receives a (1-1)-th signal; a (1-2)-th antenna which transmits or receives a (1-2)-th signal; a second antenna which transmits or receives a second signal; a (1-1)-th phase control element disposed between the (1-1)-th antenna and the signal processing device; a (1-2)-th phase control element disposed between the (1-2)-th antenna and the signal processing device; and a second phase control element disposed between the second antenna and the signal processing device, wherein the (1-1)-th signal output from the (1-1)-th phase control element and the (1-2)-th signal output from the (1-2)-th phase control element have a phase difference of 180 degrees from each other, and the second signal output from the second phase control element has a phase difference of 90 degrees from each of the (1-1)-th signal and the (1-2)-th signal.
