MULTIPLE BEAM LENS ANTENNA

摘要

The proposed multiple beam lens antenna comprises a spherical centrally symmetrical lens secured by means of connecting units (3) to an elliptical frame (2) in such a way that the centre of the lens (1) lies outside the plane of the frame (2). The frame (2) is mounted on the base (4) in such a way that it can rotate about the horizontal plane. The antenna also includes illumination units (8) on a half-ring rail (9) which is connected to the frame (2) by connecting units (11). The connecting units (3, 11) which secure the lens (1) and half-ring rail (9) to the frame are designed to be self-adjusting in their angular position and can be adjusted and move along their own axis. The half-ring rail (9) lies in the plane parallel to the plane which passes through the centre of the lens (1) and the major axis of the frame (2), while the frame (2) is mounted on the adjustable base (4) in such a way that the statically counterbalanced lens (1), frame (2) and half-ring rail (9) can rotate about the major axis of symmetry of the frame (2) and the position of the frame can subsequently be fixed.
