Parabolic reflector antenna

摘要

This specification discloses a parabolic reflector antenna, which is used as an antenna for signal transmission between the radio communication base station and the mobile terminals. By determining the curvatures and relative positions of a main-dish with a main reflecting surface and a sub-dish with a sub-reflecting surface and means of determining the size of the feedback device and relevant distances in between, the present invention improves the signal reception and emission of the parabolic reflector antenna.
