Ultra Geniş Bantlı Haberleşme Sistemleri için Çentikli Yuvarlatılmış Kelebek Anten Tasarımı

Bu çalışmada, Ultra-Geniş Bant haberleşme sistemleri için modifiye edilmiş kelebek anten yapısı önerilmiştir. Bu anten kelebek antenin kollarının yuvarlatılması ve çentik atılması ile oluşturulmuştur. Tasarlanan yapının anten parametreleri, Federal İletişim Komisyonu tarafından belirlenen kısıtlamalara göre incelenmiştir. Böylece, Geri Dönüş Kaybı (S11), Duran Dalga Oranı (VSWR), kazanç, ışıma örüntüsü ve anten empedansı 3,1 GHz -10,6 GHz frekans aralığında gözlenmiştir. Ayrıca, anten kol uzunluğunun ve dielektrik malzemenin anten performansına etkisi aynı frekans aralığında yorumlanmıştır. Elde edilen sonuçlara göre, önerilen yapı Ultra-Geniş Bant sistemleri için bant genişliği gereksinimlerini karşılamaktadır. Kazanç ve empedans değişimleri de Ultra-Geniş Bant uygulamaları için kabul edilebilir sınırlardadır. Önerilen anten CST Microwave Studio programı ile analiz edilmiştir.

Design of Notched Rounded Bowtie Antenna for Ultra-Wideband Communication Systems

In this paper, a modified bowtie antenna structure is proposed for Ultra-Wideband communicationsystems. This antenna is obtained by rounding and notching the edges of antenna arms. Antennaparameters for the designed structure are examined according to the restrictions specified by FederalCommunications Commission. Thus, Return Loss (S11), Voltage Standing Wave Ratio (VSWR), gain,radiation pattern and impedance are observed in the 3.1 GHz - 10.6 GHz frequency range. Additionally,the effect of arm length and dielectric material on antenna performance are interpreted in the same range.According to obtained results, the proposed structure satisfies the bandwidth requirements for Ultra-Wideband systems. Gain and impedance variations are also in acceptable limits for Ultra-Widebandapplications. The proposed antenna is analyzed through CST Microwave Studio program.
