An antenna unit includes an antenna substrate, a reflective plate, a receiver board, a transmitter board, a cooling plate and a connection interface. The reflective plate is disposed on an antenna element forming surface of the antenna substrate. The receiver board is disposed on a surface of the antenna substrate opposite to a surface facing the reflective plate, and has a receiver module to process a received signal . The transmitter board is disposed substantially parallel to a surface of the receiver board opposite to a surface facing the antenna substrate, and has a transmitter module to process a transmission signal. The cooling plate is disposed on a surface of the transmitter board opposite to the surface facing the receiver board and is configured to cool down heat generated by the transmitter module. The connection interface connects the transmitter board and the receiver board to transmit a signal therebetween.
