Microwave antenna having two reflectors

摘要

The subject of the invention is a microwave antenna having two reflectors. The auxiliary reflector 2 of this antenna is generated by an elliptical arc MN rotating about an axis of revolution ZZ% on which one end M of the said arc is located and its first focal point F1, generating a surface of revolution, the point M of which is directed towards the principal reflector 1. The principal reflector is generated by the rotation about the same axis of revolution ZZ% of a semi-parabola ST having as the focal point F2 the second focal point of the elliptical arc. Applications to radar and telecommunication antennas. <IMAGE>
