Well we could experiment with the concept of ESPAR (switched parasitic array antenna), where you have just one receive chain conected to the main monopole antenna e the other elements terminated on DSP-controlled varactors to tune the array. The classic concept is to perturb the varactors changing the overal impedance of the array and so and so... Angilberto. __________________________________________________ Do You Yahoo!?
