Abstract :
A novel defected ground structure (DGS) microstrip resonator is proposed. The proposed DGS resonator has the resonant and anti-resonant characteristic that is very similar to those of a surface acoustic wave resonator or a film bulk acoustic resonator (FBAR). To confirm the validity of the proposed resonator, bandpass filters were designed and implemented using series and parallel resonators.
