Abstract

In this study, an intelligent reflective surface (IRS) design consisting of a 3x4 patch surface that intentionally changes the phase angles of incoming signals for the 2.4 GHz operating frequency is presented. In the design of this IRS, FR-4 is chosen as the dielectric material, and copper is used to create both the reflecting elements and the ground plane. Phase shifting characteristic is achieved by using varactor diodes on the designed two-dimensional surface. In order to test the behaviour of the IRS, a horn antenna is also designed to be used as a source with the ANSYS HFSS (v21) program. The obtained results are presented in terms of return loss and gain values of the IRS. The results of the simulations reveal that the phase angles of the incoming signals can be adjusted as expected by changing the capacity values of the varactor diodes modelled by their equivalent circuits on the IRS.

Özet

Bu çalışmada 2.4 GHz çalışma frekansı için 3x4 yama yüzeyinden oluşan gelen sinyallerin faz açılarını değiştiren akıllı yansıtıcı yüzey (IRS) tasarımı sunulmuştur. IRS tasarımda dielektrik malzeme olarak FR-4, yansıtıcı yüzeylerde ve toprak düzlemde bakır malzeme seçilmiştir. IRS tasarımında varaktör diyot kullanılarak tasarıma faz kaydırıcı özellik kazandırılmıştır. IRS tasarımını ve tasarımın faz kaydırıcı özelliğini test etmek için gerekli kaynak boynuz anten ve varaktör diyotlar ANSYS’in HFSS (v21) programı ile tasarlanmış ve simüle edilmiştir. Simülasyon sonucunda IRS’e gelen sinyallerin IRS üzerinde bulunan varaktör diyot eşdeğer devrelerinin kapasite değerleri değiştirilerek faz açılarının değiştirilebildiği ortaya konulmuş ve tasarıma ait geri dönüş kayıpları ve kazanç değeri verilmiştir.
