Antena de seguimiento en acimut para comunicaciones vía satélite

Abstract

We present in this paper a first step of a feasibility study about a geo-satellite link from aeronautical, maritime and land mobiles, where the antenna provides a mechanical scanning in azimuth, based on a new beam tracking system. The novelty of this system is on the radiating element, which provides simultaneously at the input of the control card, the signals of both beams. This system avoids the waiting time due to the state change of the beam switch in a classical process. A laboratory prototype of the antenna has been designed, manufactured and measured, to demonstrate the possibilities of the developed technology.
