A microwave beam-forming antenna comprising:
- a main reflector installed on a surface of an antenna body;
- an array feed horn installed on a center portion of the main reflector;
- a sub-reflector disposed to be spaced apart from the array feed horn on the main reflector;
- a plurality of waveguide feeds respectively connected at one end portion of each waveguide feed to a plurality of horn antennas arranged in the array feed horn, wherein another end portion of one waveguide feed of the plurality of waveguide feeds extends to a bottom surface of the antenna body to be exposed at the bottom surface of the antenna body;
- and
- a plurality of waveguide connectors respectively connected to another end portion of the plurality of waveguide feeds, except for the one waveguide feed of the plurality of waveguide feeds, at side surfaces of the antenna body,
- wherein each of the plurality of waveguide feeds, except for the one waveguide feed, includes a bent portion at a right angle within the antenna body, and
- wherein the one end portion of each waveguide feed, except for the one waveguide feed, extends from a center portion of the antenna body to the side surfaces of the antenna body.
