Abstract :
Individually biased varactor diodes fitted to the radiating edges of microstrip patch antennas enable independent control of the resonant frequency and input impedance. The technique has been successfully applied to polarisation-agile patch antennas and it affords a solution to the problem of the change in input impedance when switching between polarisations
