Claims

[Scope of utility model registration request]

A slot antenna has multiple slots installed in the wall of a waveguide at intervals of approximately 1/2 of the wavelength in the tube, and multiple conductor rods are arranged perpendicularly to the length of the waveguide at predetermined intervals. Focusing on the grating filter and slot antenna,
A horn antenna consisting of a conductor wall that spreads in a fan shape in a plane perpendicular to the length direction of the slot antenna and a radome attached to the antenna opening, in which a plurality of horn antennas are used at a frequency lower than the operating frequency of the horn antenna. Another antenna consisting of radiating elements is provided as a flint antenna on the inner surface of the radome so that the radiating elements are spaced at regular intervals, and the grating filter is used as a reflector. A horn antenna characterized by:
