ABSTRACT:
A feedhorn includes a chassis body, a waterproof cover serving as a cover member and a dielectric antenna. The chassis body includes a waveguide having an opening. The waterproof cover is connected to the chassis body to close the opening. The waterproof cover is made of a dielectric. The dielectric antenna is placed to face the opening with the waterproof cover therebetween. Thus, the feedhorn, a radio wave receiving converter and an antenna with which the manufacturing cost can be reduced are achieved.
