Abstract:
A method of making a paraboloidal antenna with a larger focal point, comprising the steps of:varying parameters of a paraboloid reflector from a true paraboloid shape over a portion of a reflecting surface of the paraboloid reflector resulting in a plurality of focal points displaced one or more distances from each other; cutting the Paraboloid reflector with a plane into a first reflector portion having a true paraboloidal shape and a first focal point of the plurality of focal points and a second reflector portion having a true paraboloidal shape and a second focal point of the plurality of focal points, wherein the plane is substantially perpendicular or parallel to an axis of symmetry; connecting the first reflector portion and the second reflector portion; and placing a collector that collects reflected signals at all the plurality of focal points.
