- Title
COMPACT DUAL-MODE DGS RESONATORS AND FILTERS.
- Authors
Wang, L.; Guan, B.-R.
- Abstract
A novel and compact dual-mode defected ground structure (DGS) resonator is presented. Distinct characteristics of the proposed resonator are investigated. Using this type of resonator, a bandpass filter with the center frequency of 2.38GHz and the fractional bandwidth of 6.7% is simulated and fabricated. The results show that this filter not only has an inherent transmission zero near the passband, but also has a very wide upper stopband with rejection better than 20 dB up to about 12GHz.
