Beam controller for aperture antenna, and aperture antenna therewith
First Claim
1. A horn antenna, comprising:
- a waveguide;
an aperture horn of which one end is connected to the waveguide and the other end is provided with an opening, the aperture horn configured to receive a signal spatially fed from the waveguide; and
a beam controller including a feeding unit connected to the opening and provided with a plurality of slits, a dielectric layer connected to the feeding unit, and a plurality of patches connected to the dielectric layer to control a beam shape of the signal introduced into the feeding unit from the aperture horn and radiated through the patches,wherein the plurality of slits are formed to increase the strength of the signal radiated through the corresponding patch as they proceed toward the central portion of the beam controller from the edge thereof.

Abstract
The present invention relates to an aperture antenna capable of controlling a shape of a radiated beam without changing a structure of an aperture antenna by connecting a beam controller with a single aperture antenna. the aperture antenna including a beam controller according to the present invention includes: a waveguide; an aperture horn of which one end is connected to the waveguide and the other end is provided with an opening; and a beam controller including a feeding unit connected to the opening and provided with a plurality of slits, a dielectric layer connected to the feeding unit, and a plurality of patches connected to the dielectric layer to control a beam shape of a signal introduced into the feeding unit and radiated through the patches.
