The power supply has an asymmetric reflector antenna beamwidth feed horn

摘要

This design is in the wide conduct daegongmang radar antennas of horizontal deflection, and mobile satellite receiving antenna reverberation, etc. class can be applied to reflector antenna, meet its height and AFH antenna feed horn for needing to simply minimize beam width. ;The feed horn that the main object of the present invention is used as a simple structure (3) increasing horizontal beam width in the form of a rectangular mirror, by offer (5) to existing feed horn hole (1) to allow. ;Conventional feed angle (1) has the identical beam width in horizontal deflection, and vertical direction is applicable to the power supply of circular reflector (4). On the reflecting mirror of rectangular shape, the bottom for cutting a circular reflector (5) is used to reduce the height of reflector antenna, as the occasion in a mobile satellite receiving antenna reverberation. In this case, there is the power supply feed horn just like asymmetric light line width shown in Fig. 2 to be required. This is configured to implement to determine associated beam width, in horizontal deflection, through a gap (2), between (1) for modulating conventional feed angle flourishing outdoors of the subregion in addition to partition structure (3).
