Phased Array Antenna Variations: "A digital phased antenna array could be made up of many elements of different
positions shapes and sizes. In general, when receiving a signal, every element
would contribute to a positive or negative waveform, so all the elements that
are contributing a positive waveform would be switched to one terminal and all
the elements that are contributing to a negative waveform would be switched to
the second terminal. With many elements, the average voltage from a random
signal would be close to zero, only the one wished for would have a large
signal strength. With some elements pointing in different directions, signals
with different polarizations could be selected for. At the expense of added
complexity, some elements could be left out of the circuit entirely, which
would help ignore noise from marginal elements, this would require a trinary
switch. With switches which in turn choose between different capacitors or
inductors, further discrimination is possible with further complexity. "
