5G UYGULAMALARI İÇİN ULTRA İNCE METAMALZEME SOĞURUCU

Abstract

Bu çalışma, Ku/Ka-bant uygulamaları için özel olarak tasarlanmış ultra ince ve polarizasyona duyarsız bir metamalzeme soğurucuya dayanmaktadır ve bu amaçla, mikrodalga frekansında çalışan metamalzeme tabanlı soğurucu yapılar tasarlanmıştır. Bu çalışmada tasarlanan metamalzeme soğurucu yapı tamamen özgündür. Mikrodalga ve optik frekanslarda çalışan sinyal soğurucu yapıların sayısal ve simülasyon çalışmaları, sonlu entegrasyon tekniği (FIT) tabanlı bir simülasyon programı kullanılarak gerçekleştirilmiştir. Önerilen soğurucuların TE ve TM polarizasyon için normal gelişte tüm Ku/Ka bandını kapsayan %90'ın üzerinde neredeyse mükemmel bir soğuruculuğa sahip olduğu görülmüştür. Soğurma mekanizmasının daha iyi anlaşılabilmesi için rezönatör yapı üzerindeki elektrik ve manyetik alan dağılımları ve ayrıca yüzey akım dağılımları da incelenmiştir. Simülasyon çalışmaları Ku/Ka bantlarında gerçekleştirilmiştir. Diğer taraftan, simülasyon çalışmalarının doğruluğunu test edebilmek için Ku bandında tasarlanan yapının üretim ve ölçümü de yapılmıştır. Ku bandında çalışan sinyal soğurucu yapıları LPKF ProtoMat E33 kullanılarak üretilmiş ve deneysel ölçümler, horn anten ve PNA-L N5234A Mikrodalga Ağ Analizörü kullanılarak yapılmıştır. Üretimde çift tarafı bakır kaplı RT5870 alt tabaka kullanılmıştır. Üretilen yapının arka tarafı tamamen bakırla kaplı olduğu için sadece yansıma parametresi (S11) ölçülmüştür. Sayısal ve deneysel sonuçlar birbirleriyle karşılaştırılmış ve sonuçlar arasında iyi bir uyumun olduğu görülmüştür. Bu çalışma, elektromanyetik kalkanlama, gizleme ve anten performansının iyileştirilmesi açısından önem taşımaktadır.

ULTRA THIN METAMATERIAL ABSORBER FOR 5G APPLICATIONS

Abstract

This work is based on an ultra-thin, and polarization-insensitive metamaterial absorber specifically designed for Ku/Ka-band applications. For this purpose, metamaterial-based absorber structures operating at microwave frequencies have been designed. The metamaterial absorber structure designed in this study is completely novel. Numerical and simulation studies of the signal absorber structures operating at microwave and optical frequencies have been performed using a finite integration technique (FIT) based simulation program. The proposed absorbers have been found to have nearly perfect absorption over 90% for TE and TM polarizations, covering the entire Ku/Ka band under normal incidence. In order to better understand the absorption mechanism, the electric and magnetic field distributions on the resonator structure and also the surface current distributions have been investigated. Simulation studies have been conducted in the Ku/Ka bands. Furthermore, to verify the accuracy of the simulations, the fabrication and measurement of the designed Ku-band structure have also been performed. The Ku-band signal absorber structures have been fabricated using the LPKF ProtoMat E33, and experimental measurements have been made using a horn antenna and a PNA-L N5234A Microwave Network Analyzer. A double-sided copper-clad RT5870 substrate has been used in the fabrication. Because the back side of the fabricated structure is completely copper-clad, only the reflection parameter (S11) was measured. Numerical and experimental results have been compared, and good agreement has been found between the results. This study is important for electromagnetic shielding, cloaking technologies and improving antenna performance.
