Abstract

In this study, bandpass waveguide filters with resonant frequencies of 5.5 GHz, 6 GHz, and 6.5 GHz are simulated and fabricated by Computer Numerical Control (CNC) milling method. Then, the simulated and measured performance parameters are obtained and compared from 1st order to 7th filter order. By using the same WR-159 waveguide structure, the operating frequency band can be easily shifted by changing only Complementary Split Ring Resonator (CSRR)-type meta-resonators placed in the waveguide, so that the same waveguide structure can be used as a filter in different frequency band regions. The measured insertion loss (IL) values are found to be within the intervals of 0.3-1.88 dB, 0.06-0.49 dB, and 0.43-2.24 dB for the waveguide filters (WGF) at resonance frequencies of 5.5 GHz, 6 GHz, and 6.5 GHz, respectively. Simulated and measured resonance frequencies have good agreement with each other for all filter orders and these values are sufficient to use the filters proposed in this study in many applications.

Özet

Bu çalışmada, rezonans frekansları 5,5 GHz, 6 GHz ve 6,5 GHz olan bant geçiren dalga kılavuzu filtreler simüle edilmiş ve CNC frezeleme yöntemi ile üretilmiştir. Ardından, simüle edilen ve ölçülen performans parametreleri elde edilmiş ve 1. dereceden 7. dereceye kadar filtrelerin performansları karşılaştırılmıştır. Tek bir WR-159 dalga kılavuzu yapısı kullanılarak, dalga kılavuzuna yerleştirilen CSRR tipi meta-rezonatörler değiştirilerek çalışma frekans bandı kolayca kaydırılabilir. Böylece, aynı dalga kılavuzu yapısı farklı frekans bandı bölgelerinde filtre olarak kullanılabilir. Ölçülen ekleme kaybı (IL) değerlerinin, sırasıyla 5,5 GHz, 6 GHz ve 6,5 GHz rezonans frekanslarında dalga kılavuzu filtreleri (WGF) için 0,3-1,88 dB, 0,06-0,49 dB ve 0,43-2,24 dB aralıklarında olduğu bulunmuştur. Simüle edilen ve ölçülen rezonans frekansları, tüm filtre dereceleri için birbiriyle iyi bir uyum göstermektedir ve bu değerler, bu çalışmada önerilen filtrelerin birçok uygulamada kullanılabilmesi için yeterlidir.
