Geoda: Distribución de la Celda Unitaria, Composición de los Arrays y Funcionamiento

Nowadays, satellite communications are basic for the human lifestyle. In this way, a smart, conformal and multiarray antenna (GEODA) is being developed in order to receive signals from several satellites simultaneously in the1.7GHz working band. An adaptive beam system is able to follow the signals from the satellite constellation. The complex structure of the antenna is based in similar arrays of triangular shape. These arrays are divided in sub-arrays of three elements called Cells composing the single control element for the arrays main beam direction management. Fifteen cells, forty-five radiating elements, compose each triangular array of the GEODA antenna. In this paper, the working properties and the design of one cell will be shown and discussed.
