Abstract :
In this paper, we proposed a DGS (defected ground structure) microstrip resonator. The proposed DGS resonator has the resonant and anti-resonant characteristic that is very similar to those of a SAW resonator of a FBAR. In order to confirm the validity of the proposed resonator, we designed and implemented bandpass filters by using series and parallel resonators.
