Wi-Fi Uygulamaları İçin Çift Bant Mikroşerit Anten Tasarımı

Bu bildiride, Wi-Fi uygulamalarında kullanılmak üzere 2,4 GHz ve 5,8 GHz frekanslarında çalışan bir mikroşerit yama anteni tasarlanmıştır. Araştırmanın temel amacı, kompakt, üretimi kolay ve yüksek performanslı bir mikroşerit yama anteni tasarlamaktır. Antende iletken olarak üzerinde üç slot bulunan bir yama ve altında FR-4 substratı bulunmaktadır. Antenin yama ve toprak kısımlarında iletken olarak bakır tercih edilmiştir. Antenin genel boyutları 50 x 50 x 1,6 mm3'tür. Antenin çift bant aralığında çalışması için antenin yama kısmında üç adet dikdörtgen yuva açılmıştır. Ayrıca antende 50 Ω mikroşerit besleme kullanılmıştır. Anten 2.41 GHz ve 5.8 GHz frekanslarında rezonansa girmektedir. Alt (2.4 GHz) ve üst (5.8 GHz) bantlardaki anten bant genişliği değerleri sırasıyla 53,6 MHz ve 200,4 MHz'dir. Elde edilen VSWR değerleri sırasıyla 2.41 GHz rezonans frekansı için 1.49 ve 5.8 GHz rezonans frekansı için 1.08'dir. Antenin yönlülük grafiği ve ışıma özellikleri, antenin istenilen ışıma özelliklerine sahip olduğunu göstermektedir. Anten tasarımı CST Studio Suite 2020 yazılımı kullanılarak yapılmıştır.

Dual-Band Microstrip Patch Antenna Design For Wi-Fi Applications

In this paper, a microstrip patch antenna working at 2.4 GHz and 5.8 GHz frequencies is designed for use in Wi-Fi applications. The main purpose of the research is to design a compact, easy manufacture, and high-performance microstrip patch antenna. In the antenna, there is a patch with three slots on it as a conductor and the FR-4 substrate under it. Copper is preferred as a conductor in the patch and ground parts of the antenna. The overall dimensions of the antenna are 50 x 50 x 1.6 mm3. Three rectangular slots were opened in the patch part of the antenna for the antenna to work in the dual-band range. In addition, 50 Ω microstrip feed is used in the antenna. The antenna resonates at 2.41 GHz and 5.8 GHz frequencies. The antennas bandwidth values in the lower (2.4 GHz) and upper bands (5.8 GHz) are 53.6 MHz and 200.4 MHz, respectively. The VSWR values obtained are 1.49 for the 2.41 GHz resonant frequency and 1.08 for the 5.8 GHz resonant frequency, respectively. The directivity graph and radiation properties of the antenna show that the antenna has the desired radiation characteristics. The design of the antenna was made using CST Studio Suite 2020 software.
