Abstract
A front feed reflector antenna with a dish reflector has a reflector focal length to reflector diameter ratio of less than 0.25. A wave guide is coupled to a proximal end of the dish reflector, projecting into the dish reflector along a longitudinal axis. A dielectric block is coupled to a distal end of the waveguide and a sub-reflector is coupled to a distal end of the dielectric block. A shield is coupled to the periphery of the dish reflector. The sub-reflector diameter is dimensioned to be 2.5 wavelengths or more of a desired operating frequency.
