The antenna reflector shaped to cover the area and method of configuration of reflector antenna reflector modeled

摘要

"Antenna reflector shaped to cover the area and method of configuration of reflector antenna reflector modeled.Used in fixed or mobile cellular systems, comprising a primary feeder type corrugated horn (10) at an angle offset below the horizontal.And a reflector (20) on the frame (21) substantially oval.The surface is represented by a cloud of points whose coordinates correspond to a grid in the complex space defined by a function (L) not analytical.The assembly is dimensioned so as to make the edge of the reflector intercepts the beam irradiated by the horn in a contour which corresponds to a level of approximately 12 dB below the signal VinEl irradiated in the direction of the axis (18) of said horn.The said reflector is configured by a calculation process, iterative solution of a system of nonlinear equations resulting from the discretization of an equation of type monk ampu00dere.
