3.1.1.2 Main Reflector Design
The main reflector is one of the core components of the antenna system. Its theoretical
curved surface is formed by synthetic curve rotating around the axis of the antenna.
The antenna reflector is divided into multiple plates because of cumulative materials,
manufacturing engineering, final assembly adjustment, etc. The reflector is divided into
three rings. Inner ring reflector is divided into 16 same sector unit plates; the middle
ring is divided into 32 sector unit plates and the outer ring is divided into 32 sector unit
plates. So the main reflector of antenna is composed of 80 reflector units, as shown in
Fig.2.1-4 and 2.1-5.
