Multiple receiver aerial for satellites - has hollow dish shape with hollow mirror and several receiver modules at all focal points

摘要

The multiple receiver aerial for satellites is in the form of a hollow mirror. It is dish-shaped and has a special arrangement of several receiver modules in the geometrical location of all focal points. The mirror is of collector type and has at the focal points active radiating artificial earth satellites with an orbital path of geo-stationary type near the equator for simultaneous reception. The aerial has a focal point on a main axis of the mirror to which a beam is parallel on impingement. The focal point is in the middle between the dish centre point and the inner, reflecting surface of the aerial. ADVANTAGE - Facility for reception of several different satellites by fixed dish aerial.
