1. A reflector antenna, comprising:
a reflector having a curved reflecting surface that extends around a longitudinal center axis, wherein the curved reflecting surface is defined by rotating a concave curve around the longitudinal center axis and wherein one end of the concave curve defines an apex on the longitudinal center axis;
a ground plane extension having a flat reflecting surface abutting an edge of the reflector and extending radially away from the longitudinal center axis, the reflector and the ground plane being configured to reflect radiation beams;
a phased array feed arranged spaced apart from and opposite to the reflecting surfaces of the reflector and the ground plane extension; and
a tapered collar comprising an inner reflective surface facing the reflector and the ground plane extension, the tapered collar tapering outwardly away from the phased array feed and towards the reflector and the ground plane extension.
