C Bandında Çalışan Yakınlık-Bağlantılı-Beslemeli Logo Anten Tasarımı

Abstract

Logo antenler çeşitli alanlarda yaygın olarak kullanılmakta olup, işlevselliğin yanı sıra estetiğin, reklamın ve tanınırlığın da önemli olduğu bu çağda, bu tür antenlere olan talep de artmaktadır. Bu çalışmada, C bandında (4.87 GHz) çalışan, Aydın Adnan Menderes Üniversitesi amblemli bir logo anteni, kablosuz haberleşmede kullanılmak üzere tasarlanmış ve incelenmiştir. Anten tasarımında, 1.6 mm kalınlığında ve epsilon değeri 3.8 olan iki adet FR4 katmanı kullanılmış ve anten için iletken olmayan besleme türlerinden biri olan yakınlık-eşlenik besleme yöntemi tercih edilmiştir. Anten, CST Microwave Studio programı kullanılarak tasarlanmış ve simülasyonlarda, bant genişliği, S11, kazanç ve ışıma deseni analiz edilmiştir. En iyi performansı gösteren anten boyutları parametrik taramalar yapılarak belirlenmiştir. Simülasyon çalışmaları sonucunda, tasarlanan antenin |S11|<-10dB ve |S11|<-6 dB geri dönüş kaybı değerleri için bant genişlikleri sırasıyla 241 MHz ve 483 MHz olarak bulunmuştur. Antenin maksimum kazancı 4.567 dBi, VSWR değeri ise 1,45 olarak bulunmuştur.

Proximity-Coupled-Fed Logo Antenna Design Operating in the C Band

Abstract

Logo antennas are extensively utilized in various fields and in this era where aesthetics, advertising and recognition are important as well as functionality, the demand for such antennas is also on the rise. In this study, a logo antenna with the emblem of Aydın Adnan Menderes University operating in the C band (4.87 GHz) was designed and examined for use in wireless communication. In the antenna design, two FR4 layers with a thickness of 1.6 mm and an epsilon value of 3.8 were utilized, and the proximity-coupled feeding method, which is one of the non-conducting feeding types, was preferred for the antenna. The antenna was designed using the CST Microwave Studio program ,and in the simulations, bandwidth, S11, gain and radiation pattern were analyzed. The antenna dimensions showing the best performance were determined by performing parametric sweeps. As a result of simulation studies, the bandwidths of the designed antenna for |S11|<-10dB and |S11|<-6 dB return loss values were found to be 241 MHz and 483 MHz, respectively. The maximum gain of the antenna was found to be 4,567 dBi and the VSWR value was found to be 1.45.
