A Novel Stacked Monopole Microstrip Antenna for Ultra-Wideband Applications

Öz

In this study, a novel stacked monopole antenna with microstrip-fed is presented for ultra-wideband (UWB) applications covering 3.1 GHz–10.6 GHz. Three stacked identical radiating elements are utilized to improve the impedance bandwidth. The electrical characteristics of the proposed antenna and also achievable performance are analyzed with the use of an electromagnetic simulation tool based on method of moments (MoM). Both the stacked layer as the parasitic elements and the radiating element of the antenna are fabricated with FR4 substrate material. The permittivity, length, width and thickness of each layer are 4.4, 40 mm, 40 mm and 1.55 mm, respectively. Dimensions of the antenna and parasitic element are optimized with the use of artificial bee colony (ABC) algorithm. The simulation and measurement results exhibit a good performance such as bandwidth, return loss and radiation pattern through UWB range. As a result of this study, a microstrip antenna which is a versatile alternative for wireless communication in UWB applications is obtained.

Ultra Geniş Bant Uygulamaları için Yeni Bir Yığın Monopole Mikroşerit Anten

Öz

Bu çalışmada 3,1 GHz–10,6 GHz aralığını kapsayan çok geniş band (ÇGB, Ultra-wideband-UWB) uygulamaları için mikroşerit beslemeli yeni bir yığın monopol anten sunulmuştur. Empedans bant genişliğini geliştirmek için üç yığınlı özdeş ışıma elemanları kullanılmıştır. Önerilen antenin elektriksel karakteristikleri ve ulaşılabilir performansı, moment metodunu (MoM) temel alan bir elektromanyetik benzetim aracı kullanılarak analiz edilmiştir. Parazitik elemanların yer aldığı yığınlanmış katmanlar ile antenin ışıma elemanının yer aldığı katmanlar, FR4 alttaş malzemesi kullanılarak üretilmiştir. Her katmana ait dielektrik sabiti, uzunluk, genişlik ve kalınlık değerleri sırasıyla 4,4, 40 mm, 40 mm ve 1,55 mm’dir. Antenin ve parazitik elemanın boyutları yapay arı kolonisi (YAK, Artificial Bee Colony-ABC) algoritması kullanılarak optimize edilmiştir. Benzetim ve ölçüm sonuçları, ÇGB boyunca bant genişliği, geri dönüş kaybı ve ışıma diyagramı olarak iyi bir performans sergilemektedir. Bu çalışmanın bir sonucu olarak, ÇGB uygulamaları içinde kablosuz haberleşme için birçok işe uygun bir alternatif mikroşerit anten elde edilmiştir.
