24 GHz’de Geniş Bantlı ve Düşük Maliyetli Mikroşerit Slot Anten Tasarımı ve Analizi

Öz

Bu çalışmada, beşinci nesil (5G) mobil iletişim uygulamaları için düşük maliyetli bir mikroşerit slot anteninin tasarımına, sayısal analizine ve üretimine odaklanılmıştır. Bu araştırmanın temel amacı 5G frekans bandında 24 GHz frekansında çalışan bir mikroşerit slot anteninin incelenmesidir. Bu frekans bandı, yüksek hızlı kablosuz iletişim için çeşitli frekans bantlarını kullanan 5G iletişim aralığının oldukça içerisindedir. Anten düşük maliyetli ve mobil iletişim cihazlarına uygun olacak şekilde tasarlanmıştır. Anten, baskılı devre kartlarında yaygın ve uygun fiyatlı olarak kullanılan ve 25 × 20 × 1.6 〖mm〗^3 kompakt boyutuna sahip bir FR-4 alt tabaka üzerine tasarlanmış ve üretilmiştir. Bu alt tabaka seçimi, uygun maliyetli bir anten oluşturma hedefiyle uyumludur. Antenin performansını analiz etmek için iki hesaplama aracı kullanıldı. Bunlardan ilki, Sonlu Fark Zaman Alanı (FDTD) yöntemini temel alan Hesaplamalı Elektromanyetik Simülatör (CEMS) yazılımı, ikincisi ise Sonlu Entegrasyon Tekniği (FIT) tabanlı CST yazılımıdır. Bu araçlar, çeşitli parametreleri değerlendirmek için anten tasarımında ve simülasyonunda yaygın olarak kullanılmaktadır. 24 GHz’de önerilen antenin maksimum kazanç değeri 3.56 dBi'dir. Önerilen antenin ölçümleri Keysight Network Analizörü kullanılarak yapılmıştır.

Design and Analysis of A Wideband and Low-Cost Microstrip Slot Antenna at 24 GHz

Öz

In this study the design and numerical analysis of a low-cost microstrip patch antenna for fifth-generation (5G) mobile communication applications are focused. The main objective of this research is to investigate a microstrip patch antenna that operates in the 5G frequency band at 24 GHz. These frequency band is well within the range of 5G communication, which utilizes a variety of frequency band for high-speed wireless communication. The antenna is designed to be low-cost and suitable for mobile communication devices. The antenna is designed and fabricated on a low-cost FR-4 substrate having compact size 25 × 20 × 1.6 〖mm〗^3, which is a common and affordable material used in printed circuit boards. This choice of substrate aligns with the goal of creating a cost-effective antenna. Two computational tools are used to analyze the antenna's performance. The first is a Computational Electromagnetic Simulator (CEMS) software based on the Finite-Difference Time-Domain (FDTD) method, and the second is CST software, which is based on the Finite Integration Technique (FIT). These tools are commonly used in antenna design and simulation to assess various parameters. The maximum gain value of the antenna is 3.56 dBi at 24 GHz. The measurement of the proposed antenna has been performed using the Keysight Network analyzer.
