- 초록
- The millimeter wave dual-reflector antenna for low Earth orbit (LEO) communication satellite providing the beam scanning within hemispherical sector by rotations of reflector and subreflector is under consideration. The results of optimization of the antenna geometry and feed horn characteristics which provide the antenna high gain and low side lobe level in the whole scanning sector are presented.
