Antenna device and transmit-receive unit using the same
 An antenna device has less change in gain during beam scanning, caused by the displacement of a primary radiator with respect to a dielectric lens, and scanning can be carried out over a large angular range at uniform gain. A primary radiator has a focal plane in a position deviating from the optical axis of a dielectric lens, and when the primary radiator intersects the optical axis, the primary radiator leaves the focal plane. As a consequence, by moving the primary radiator away from the optical axis to other positions, change in the gain caused by change in the open efficiency and aberration can be reduced.
