<p>The aim of the present invention is a sub-reflector of a dual-reflector antenna comprising: a first end having a junction of a first diameter, adapted for coupling to the end of a waveguide, a second end, having a second diameter greater than the first diameter, a convex reflective internal surface placed at the second end having an axis of revolution, an external surface of the same axis, joining the two ends, a dielectric material extending between the first and the second ends and limited by the internal surface and the external surface, In accordance with the invention, the external surface has a convex profile described by a polynomial equation of the sixth degree of the formula: y = ax6 + bx5 + cx4 + dx3 + ex2 + fx + g where a is not zero.</p> |
