Front fed parabolic reflector
WebThe meaning of PARABOLIC REFLECTOR is a concave mirror that has the form of a paraboloid of revolution so that rays emanating from the geometrical focus and reflected … WebThe crosspolarisation levels of symmetric front-fed paraboloids and dual-reflector antenna systems have been determined for a wide range of reflector and feed parameters. It is shown that minimum crosspolarisation is achieved when the feed radiates a polarisation-pure field, and, in this case, the front-fed paraboloid is superior.
