Abstract :
This work demonstrates a useful application of the ferroelectric thin film varactor technology in the design of reconfigurable microstrip patch antennas. Results show that the resonant frequency of the microstrip patch antenna can be tuned by varying the applied DC voltages on the ferroelectric varactor. A resonance frequency shift from 12.4 GHz to 13.8 GHz was observed for a small dc bias voltage of only 2.5 V.
