摘要： An antenna device capable of increasing the speed of scanning as well as extending the scanning angular range of a beam to obtain a high gain. A radar module and a communication apparatus having enhanced detection capabilities obtainable by using the antenna device. In the antenna device, electromagnetic waves radiated from a primary radiator are transmitted to a plurality of openings, e.g., dielectric lenses and/or reflectors or optical transmitters. The dielectric openings are arranged on a fixed portion and the primary radiator is arranged on a moving portion. The moving portion is displaced relatively with respect to the fixed portion. This arrangement enables the selection of an opening used for receiving each of the electromagnetic waves from the primary radiator to change the direction of the beam.

摘要： 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.

摘要： A balanced-type mixer having easier mounting of a circuit board into a dielectric line apparatus, easier matching between a dielectric line and diodes, and reduced conversion loss. A first conductor pattern is disposed in a direction substantially perpendicular to first dielectric strips which constitute a first NRD guide, first and second filter circuits are provided at positions on opposite sides of the first dielectric strips, thus forming a first resonance circuit, and beam lead diodes are mounted in series within the resonance circuit. Further, a second conductor pattern is extended substantially from the midpoint between the filter circuits, and a third filter circuit is provided, thus forming a second resonance circuit. A second NRD guide based on second dielectric strips is connected to the second resonance circuit.
