Abstract

In these days, with the improvement of wireless and mobile communication, Wi-Fi technology is everywhere in life. When wireless communication standards are examined, it is observed that 2.4 GHz (2.4-2.4835 GHz) and 5 GHz (5.15-5.825 GHz) frequency bands are used as the Wi-Fi frequency band. Therefore, in this paper, a microstrip Wi-Fi antenna design with dual band performance at 2.4 GHz and 5 GHz frequencies has been achieved. Thanks to the choice of microstrip antenna. It will be ensured that the proposed antenna has the advantageous features of microstrip antennas compared to other antennas. The feed of the antenna will realize with a microstrip line. FR-4 substrate is used as dielectric material with a thickness of 0.8 mm. Thanks to the preferred materials and cheap production cost, fabrication of the antenna is considered. The CST Studio Suite is preferred by the world's largest technology and engineering companies, as it provides a market advantage over the products by providing a shorter development period and lower cost. The design stages of the antenna have been carried out using CST Studio Suite. Also, important parameters of the antenna have been examined and optimized bandwidth, input impedance, resonance frequency, reflection coefficient, return loss, etc. As a result, dual-band Wi-Fi antenna design has been determined with wide bandwidth and high gain.

2.4 GHz ve 5 GHz Wi-Fi Uygulamaları için Çift Band Anten Tasarımı

Abstract

Günümüzde kablosuz ve mobil iletişimin gelişmesiyle birlikte Wi-Fi teknolojisi hayatın her yerinde bulunmaktadır. Kablosuz iletişim standartları incelendiğinde Wi-Fi frekans bandı olarak 2.4 GHz (2.4-2.4835 GHz) ve 5 GHz (5.15-5.825 GHz) frekans bantlarının kullanıldığı görülmektedir. Bu nedenle, bu bildiride, 2.4 GHz ve 5 GHz frekanslarında, çift bant performansa sahip bir mikroşerit Wi-Fi anten tasarımı elde edilmiştir. Mikroşerit anten seçilmesi sayesinde, mikroşerit antenlerin diğer antenlere göre avantajlı özelliklerinden faydalanarak önerilen antenin avantaj elde etmesi sağlanmıştır. Antenin beslemesi mikroşerit hat ile gerçekleştirilecektir. Dielektrik malzeme olarak 0.8 mm kalınlığında FR-4 malzemesi kullanılmaktadır. Antenin fabrikasyonu göz önünde bulundurularak tercih edilen malzemeler ona göre seçilmiş ve ucuz üretim maliyeti amaçlanmıştır. CST Studio Suite, CST ortamında geliştirilen ürünlere daha kısa geliştirme süresi ve daha düşük maliyet sağlayak diğer ürünlere göre pazar avantajı sağladığından dolayı dünyanın en büyük teknoloji ve mühendislik şirketleri tarafından tercih edilmektedir. Bu yüzden, antenin tasarım aşamaları CST Studio Suite kullanılarak gerçekleştirilmiştir. Ayrıca antenin önemli olan bazı parametreleri incelenmiş ve bant genişliği, giriş empedansı, rezonans frekansı, yansıma katsayısı, geri dönüş kaybı vb. parameteler optimize edilmiştir. Sonuç olarak, geniş bant genişliğine sahip ve yüksek kazançlı çift bantlı Wi-Fi anten tasarımı belirlenmiştir.
