More Information
Summary:Provided is an antenna device, which comprises a parabolic reflector; a dielectric support; a sub-reflector connected to an upper end of the dielectric support; and a waveguide connected to a lower end of the dielectric support, wherein the parabolic reflector has a curved surface with a ratio of focal length to a diameter greater than a predetermined value for high gain, and a corrugation for suppressing cross polarization is formed in one region of the dielectric support. 안테나 장치로서, 파라볼릭 반사판; 유전체 지지대; 상기 유전체 지지대의 상단부에 연결되는 부반사판; 및 상기 유전체 지지대의 하단부에 연결되는 도파관을 포함하고, 상기 파라볼릭 반사판은 고이득을 위해 초점 거리 대 직경의 비율(ratio of focal length to diameter)이 기 설정된 값보다 큰 곡면을 갖고, 상기 유전체 지지대의 일 영역에 교차편파 억제를 위한 주름(corrugation)이 형성되는, 안테나 장치를 제공한다.
