Bu çalışma, ışıma kayıplarını azaltmak için alttaş entegre dalga kılavuzu (AED) geçişini mikroşeritten uygulayan çift bantlı bir bant geçiren filtre tasarımı sunmaktadır. Önerilen filtre, boyutunu en aza indirmek ve çift negatif özellik kazanmak için tamamlayıcı ayrık halka rezonatörü (TAHR) ile yüklenmiştir. İstenilen ikinci frekansta rezonansa sahip olmak için TAHR'ın içine papyon şeklinde bir yuva kazınmıştır. Benzetim sonuçları gerçekleştirildikten sonra, tasarlanan filtre Rogers RT5880 dielektrik alttaş üzerinde üretilmiş ve deneysel sonuçlar benzetim sonuçlarıyla karşılaştırılmıştır. Önerilen filtre, sırasıyla %22,05 ve %26,29 kesirli bant genişliği değerleri ile 6,57 ve 12,55 GHz'de merkez frekanslara sahiptir. Ayrıca sunulan filtre, 0,327λg×0,352λg (burada λg, ilk geçiş bandının merkez frekansında yönlendirilen dalga boyudur) boyutuyla en iyi bant genişliği-boyut sonucunu sunmaktadır.

Dual Band Modified Complementary Split Ring Resonator Loaded Substrate Integrated Waveguide Based Bandpass Filter

Öz

This study presents a dual-band bandpass filter design that implements microstrip to substrate integrated waveguide (SIW) transition to decrease radiation losses. The proposed filter is designed with using four complementary split ring resonators (CSRR) to minimize its size and to gain double negative property. A bowtie shaped slot is etched inside CSRR to have a second resonance at the spectrum. After the simulation results are performed the designed filter is fabricated on a Rogers RT5880 dielectric substrate and the experimental results are compared with the simulation results. The proposed filter has center frequencies at 6.57 and 12.55 GHz with fractional bandwidth (FBW) of 22.05% and 26.29%, respectively. Moreover, the presented filter offers the best bandwidth-to-size result with the size of 0.327λg×0.352λg (where λg is the wavelength at the first passband’s center frequency).
