Farklı pin konfigürasyonlarina sahip mantar benzeri elektromanyetik bant aralığı yapıları ile geliştirilmiş yeni bir mikroşerit yama anten tasarımı

Öz

Bu çalışmada, bir mikroşerit yama anten ve farklı pin konumlarına sahip mantar benzeri EBG yapıların uygun kombinasyonlarıyla tasarımlar sunulmuştur. Referans antenin performansı kaldırılan ve/veya merkezden kaydırılan pin konfigürasyonarına sahip tasarımlarla geliştirilmiştir. Özelikle antenin yayın yapan yamasına en yakın olan EBG yapıların birinci sırasından kaldırılan ve/veya kaydırılan pinlerin anten performansı üzerindeki etkisinin daha belirgin olduğu farklı tasarımlarla gözlenmiştir. Önerilen tasarımlarla, referans antene göre %32’ye kadar bant genişliği iyileştirmesi ve 2.9 dBi’ye kadar kazanç arttırımı sağlanmıştır. Referans antenin 16.9 dB olan ön/arka (F/B) oranı sunulan tasarımlarla 26 ile 29 dB arasındaki değerlere iyileştirilmiştir. Ayrıca, sunulan antenlerin tek katmanlı basit tasarımları üretimlerini kolaylaştırırken, 0.05 ile iyi bir ince profil değeri (h/𝜆0, 𝜆0 merkez frekanstaki boş uzay dalga boyudur) de sağlar.

A novel microstrip patch antenna design enhanced by mushroom like electromagnetic band gap structures with different via configurations

Abstract

In this study, the designs with suitable combinations of a microstrip patch antenna and mushroom like EBG structures having different via locations are presented. The performance of the reference antenna is improved with the designs having removed and/or offset via configuration. It has been experienced with different designs that the vias removed and/or shifted from the first row of EBG structures, which are closest to the radiating patch of the antenna, have a significant effect on antenna performance. With the proposed designs, up to 32% bandwidth enhancement and up to 2.9 dBi gain increment are achieved according to the reference antenna. Moreover, the front to back ratio (F/B) of the reference antenna is enhanced to values between 26 and 29 dB from the 16.9 dB by the presented designs. In addition, while the simple single layer designs of the presented antennas facilitate their manufacturing, they also achieve a good thin profile merit (h/𝜆0 , 𝜆0 is the free-space wavelength at the centre frequency) with a value of 0.05.
