The developments of the wireless communications technology, the Terahertz (THz) frequency band of the electromagnetic spectrum becomes promising and recently has the researchers’ attention to be utilized in several applications such as medical, indoor communications for personal networks, and the military applications. The main issues in this frequency band are the construction of a compact, high-performance antenna design; as in this frequency band, the material properties for conduction decrease as the frequency increases, and therefore the performance of the antenna diminishes. In this paper, we propose a graphene-based bowtie microstrip antenna, the performance of the graphene material in the THz frequency band is analysed based on the finite integration of the Computer Simulation Technology (CST) software. The graphene-based bowtie patch printed on a silicon dioxide substrate with a fully copper ground plane printed on its bottom. The proposed graphene plasmonic bowtie antenna covers a range of 0.1-10 THz band frequency with good gain in the range of 2-19 dBi in the mentioned band.

Terahertz Uygulamaları için Grafen Malzemesine Dayalı Mikroşerit Bowtie Anten Tasarımı ve Optimizasyonu

Öz

Kablosuz iletişim teknolojisindeki gelişmeler, elektromanyetik spektrumun Terahertz (THz) frekans bandı umut verici hale geliyor ve son zamanlarda araştırmacıların dikkatini tıbbi, kişisel ağlar için iç mekan iletişimi ve askeri uygulamalar gibi çeşitli uygulamalarda kullanmaya başladı. Bu frekans bandındaki ana konular, kompakt, yüksek performanslı bir anten tasarımının oluşturulması; bu frekans bandında olduğu gibi, frekans arttıkça iletim için malzeme özellikleri azalmakta ve dolayısıyla antenin performansı düşmektedir. Bu yazıda, grafen tabanlı bir papyon mikroşerit anten öneriyoruz, grafen malzemesinin THz frekans bandındaki performansı, Bilgisayar Simülasyon Teknolojisi (BST) yazılımının sonlu entegrasyonuna dayalı olarak analiz ediliyor. Alt kısmında tamamen bakır bir zemin düzlemi bulunan bir silikon dioksit substratı üzerine basılmış grafen bazlı papyon yaması. Önerilen grafen plazmonik papyon anten, 2-19 dBi aralığında iyi kazanç ile 0.1-10 THz bant frekansını kapsar.
