Abstract

With the renewed and changing technology in recent years, wireless communication has increased its importance in engineering, communication, transportation and almost every field. In this study, a Wi-Fi antenna with 2.4 GHz operating frequency, which is one of the leading studies of antenna technology, which can be used in wireless communication technology, has been designed. Wi-Fi antenna is very important for this technology, which has become indispensable for everyone today. To design the Wi-Fi antenna, the operating frequency specified in the IEEE 802.11 standards has been taken into account. While choosing the antenna model, micro-strip antenna was preferred due to its geometry, lightness, low production cost and compactness. While designing the antenna, CST Microwave Studio program was used and necessary measurements were made. While designing the antenna, FR-4 substrate with a dielectric coefficient of 4.3 and a thickness of 1.6 mm was used. Copper was used as the material for the ground and patch parts. As a result of the design, most of the intended goals were achieved. Graphs were analyzed from the CST microwave studio program. When the required S parameter value is examined; The antenna obtained as a result of this study operates in the 2.26 GHz-2.38 GHz band range, which is the targeted frequency of 2.4 GHz. The Wi-Fi antenna obtained in this study; return loss value is 25.90dB and gain value is 4.66 dBi. These results are acceptable according to the standards

Kablosuz Wi-Fi Uygulaması için 2.4GHz'de Çalışan Mikroşerit Yama Anten Tasarımı ve Yorumlanması

Abstract

Son yıllarda yenilenen ve değişen teknoloji ile kablosuz iletişim mühendislik, iletişim, ulaşım ve hemen her alanda önemini artırmıştır. Bu çalışmada, kablosuz iletişim teknolojisinde kullanılabilecek anten teknolojisinin önde gelen çalışmalarından biri olan 2.4 GHz çalışma frekansına sahip bir Wi-Fi anteni tasarlanmıştır. Günümüzde herkes için vazgeçilmez hale gelen bu teknoloji için Wi-Fi anteni oldukça önemlidir. Wi-Fi anteni tasarlanırken IEEE 802.11 standartlarında belirtilen çalışma frekansı dikkate alınmıştır. Anten modeli seçilirken geometrisi, hafifliği, düşük üretim maliyeti ve kompaktlığı nedeniyle mikro şerit anten tercih edilmiştir. Anten tasarımı yapılırken CST Microwave Studio programı kullanılmış ve gerekli ölçümler yapılmıştır. Anten tasarlanırken dielektrik katsayısı 4,3 ve kalınlığı 1,6 mm olan FR-4 substratı kullanılmıştır. Zemin ve yama parçaları için malzeme olarak bakır kullanılmıştır. Tasarımın bir sonucu olarak, amaçlanan hedeflerin çoğuna ulaşıldı. Grafikler, CST mikrodalga stüdyo programından analiz edildi. İstenilen S parametre değeri incelendiğinde; bu çalışma sonucunda elde edilen anten, hedeflenen frekans olan 2.4 GHz olan 2.26 GHz-2.38 GHz bant aralığında çalışmaktadır. Bu çalışmada elde edilen Wi-Fi anteni; geri dönüş kayıp değeri 25.90dB ve kazanç değeri 4.66 dBi'dir. Bu sonuçlar standartlara göre kabul edilebilir niteliktedir.
