Abstract :
In this communication a reflector antenna is presented as a feasible solution for Local to Multipoint Distribution System base station with a reconfigurable number of sectorial beams. The antenna is an improved version of the hourglass reflector antenna with a shaped profile to obtain a cosecant-squared elevation pattern, and with a feed array which is designed to achieve adequate and reconfigurable beamwidth in the horizontal plane.
