Abstract (en)
[origin: EP1798814A2] An antenna comprises: a main reflector being a body of revolution of arbitrary curve which axis diverges from axis of the revolution; a sub-reflector being a body of the revolution of arbitrary curve along the axis of revolution, having a circle and a vertex pointing to the main reflector and being placed between the circle and the main reflector; a radiator being located along the axis of revolution and being placed between the main reflector and the sub-reflector; and wherein the main reflector and the sub-reflector are: z m r ¢ D = ˆ‘ n = 0 4 ˆ‘ m = 0 6 qm n , m ¢ D m - n + 1 ¢ r n , z s r ¢ D = ˆ‘ n = 0 4 ˆ‘ m = 0 6 qs n , m ¢ D m - n + 1 ¢ r n , - z, r are coordinates of the main reflector and the sub-reflector measured in millimeters, - Index m corresponds to the main reflector, index s to the sub-reflector, - D is the main reflector diameter measured in millimeters.
