摘要: A reflector antenna comprising a sub-reflector (1) for receiving a radio wave radiated from the opening of a primary radiator (3) and reflecting it, and a main reflector (2) for receiving the radio wave reflected from the sub-reflector (1) and radiating it into the space. Shapes of the sub-reflector (1) and the main reflector (2) are designed such that the power in a region of the main reflector (2) where the sub-reflector (1) is projected in parallel with the radiating direction of the main reflector (2) is not higher than a first threshold level and the radiation pattern of the antenna dependent on other region of the main reflector (2) has desired characteristics.
