Abstract

In this study, an antenna is proposed that operates at THz spectrum for sixth generation (6G) short-range future wireless communications. A modified photonic band gap (MPBG) substrate is employed to design an octagonal ring shaped microstrip patch antenna with wideband and high gain properties. Unlike the conventional photonic band gap (PBG) form, the proposed MPBG substrate structure is created by variable sized cylindrical air holes. The radii of each air cylinder in the row is determined with the help of particle swarm optimization (PSO) algorithm, where the goal is set to achieve the highest gain and impedance bandwidth (S_11≤-10 dB) possible. The simulation results of the antennas that are built on 1) non-PBG, 2) conventional PBG and 3) the proposed MPBG substrate structures are compared. It is observed that the radiation performance is most enhanced by implementing MPBG structure. In comparison to the antenna without PBG, the reported MPBG structure offers almost 300% gain and 11% bandwidth improvement. To summarize, the designed antenna with its proposed MPBG substrate structure achieves an excellent radiation performance within a wide operating bandwidth.

Özet

Bu çalışmada, altıncı nesil (6G) kısa menzilli geleceğin kablosuz iletişimi için THz spektrumunda çalışan bir anten önerilmiştir. Geniş bant ve yüksek kazanç özelliklerine sahip sekizgen halka şeklinde bir mikroşerit yama anteni tasarlamak için değiştirilmiş bir fotonik bant aralığı (MPBG) kullanılır. Geleneksel fotonik bant aralığı (PBG) formunun aksine, önerilen MPBG substrat yapısı, değişken boyutlu silindirik hava delikleri tarafından oluşturulur. Sıradaki her hava silindirinin yarıçapı, hedefin mümkün olan en yüksek kazanç ve empedans bant genişliğini (S_11≤-10 dB) elde etmek olan parçacık sürü optimizasyonu (PSO) algoritması yardımıyla belirlenir. 1) PBG olmayan, 2) geleneksel PBG ve 3) önerilen MPBG substrat yapıları üzerine kurulan antenlerin simülasyon sonuçları karşılaştırılmıştır. Radyasyon performansının en çok MPBG yapısının uygulanmasıyla arttığı gözlemlenmiştir. PBG'siz antenle karşılaştırıldığında, bildirilen MPBG yapısı neredeyse %300 kazanç ve %11 bant genişliği iyileştirmesi sunuyor. Özetlemek gerekirse, önerilen MPBG substrat yapısı ile tasarlanan anten, geniş bir çalışma bant genişliği içinde mükemmel bir radyasyon performansı elde etmektedir.
