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 the
1.7GHz 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.
