ABSTRACT:
The present invention is applied to a slotted waveguide antenna assembly which comprises a slotted waveguide having a plurality of slots, a reflector having an aperture in front of the slotted waveguide and reflecting radiated electromagnetic wave for forming directive beam, and a mounting portion for mounting the antenna assembly onto a place where the antenna assembly is to be installed.
In such an antenna assembly, a fixing member is provided on the reflector at a position spaced from the slotted waveguide. The fixing member extends between the opposite walls of the reflector and fixed thereto. The fixing member has an end which projects outwardly from the wall of the reflector to form the mounting portion. The fixing member is sufficiently thin as compared with the working wavelength.
The slotted waveguide antenna assembly may have a dielectric wave-guiding arrangement.
