| Abstract: | An improved spiral compact microstrip resonant cell (SCMRC) was presented. The improved SCMRC with microstrip open stub lines was designed to achieve 50Ω port impedance in the low-pass band. Also, the microstrip open stub liens are resonant at the stop-band of the SCMRC resulting in the stronger slow-wave effect and wider stop-band. The proposed improved SCMRC was designed, fabricated, and measured. It shows the lower insertion loss, improved return loss in the low-pass band, and wider stop-band with compact size. |
| Keywords: | microstrip open stub line spiral compact microstrip resonant cell(SCMRC) slow-wave stop-band |
