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...
