本論文設計四個改良型雙模雙環濾波器,其中主要是使用電壓電流耦合技術與雙模微擾源的應用。在結構上分,典型的雙模雙環濾波器使用扇形殘支與與弧線耦合,共平面波導饋入雙模雙環型濾波器則使用T型饋入線耦合外環,同時使用殘支與槽口微擾源調整,激發響應頻段,並達成阻抗匹配的技術。文中所設計的兩個同心環決定響應頻率,可獲得1.2GHz與2.4GHz兩個頻段,適用於無線影像安全連結與無線區域網路的通訊系統之中。
改良型共平面波導饋入雙模雙環結構經由串接技術後,具有最佳的濾波器特性,包含低介入損耗(2.17/2.01 dB),通帶頻寬外的高衰減特性(-60.1/-67.5 dB),並且在1.268/2.452 GHz兩個頻段,呈現對稱性的頻寬(11.44 %/13.66 %)。
Novel design of four improved dual-mode double-ring resonators using voltage-couples and dual-mode perturbations are proposed here. Typical DMDRR using curved couples and radial stubs, CPW-fed DMDRR using T-shaped coupling strip to couple the outer ring and with stub/notch perturbations for adjusting are studied. Two concentric rings determine the certain resonated frequencies of 1.2/2.4GHz dual bands for Wireless Video Security Links and Wireless LAN Systems communication system.
The cascaded CPW-fed DMDRR exhibit a good performance including low insertion loss (2.17/ 2.01 dB), high out-of-band rejection level (-60.1/-67.5 dB) and symmetry wider band (11.44 %/13.66 %) among 1.268/2.452 GHz dual bands.
