ANTENNA DEVICE, AND TRANSMITTING/RECEIVING APPARATUS

摘要

An improved antenna device is provided which is easy to be made compact in size and easy to deflect a beam at a high speed. Further, a transmitting/receiving apparatus using the improved antenna device is provided which is capable of performing a detection within a large range. In particular, a primary radiator and a first transmission line combined with the primary radiator are provided on a movable section, a second transmission line electromagnetically combined with the first transmission line and a dielectric lens with a position of said primary radiator serving as a generally focal point surface are provided on a fixed section. Further, a structure is provided capable of deflecting the beam by displacing the movable section. Also, means is provided to detect the position of the movable section and a control means is provided for displacing the movable section in accordance with a position designating signal of the movable section.
