Sector radiation system with several radiators - has sector horn outlet with metal grid consisting of elements parallel and perpendicular to waveguide axis

摘要

The sector radiators consist of window, pref slots in the narrow wall of a waveguide. A sector horn lateral surfaces are perpendicular to the waveguide axis. The horn outlet aperture has a metal grid (4) consisting of metal elements parallel to the waveguide (1) axis, and of transverse strips perpendicular to the waveguide (1) axis. The metal used may be benyllium copper or aluminium, and the frame is attached to a closure plate (5), of fibre-glass or resin, by means of an adhesive substance.
