An improved asymmetric defected ground structure cell and its application to lowpass filter
An improved asymmetric defected ground structure cell is presented and analyzed. Based on this structure, a microstrip lowpass filter with low passband loss and high stopband suppression is designed and fabricated. Measured passband losses are below 1 dB, and a sharp slop is obtained at passband fre...

| Zusammenfassung: | An improved asymmetric defected ground structure cell is presented and analyzed. Based on this structure, a microstrip lowpass filter with low passband loss and high stopband suppression is designed and fabricated. Measured passband losses are below 1 dB, and a sharp slop is obtained at passband frequency fringe. The suppression is no |
