Öz

Bu çalışma, milimetre dalga frekans bandında çalışan beşinci nesil (5G) kablosuz iletişim sistemlerinde kullanılmak üzere tasarlanmış, kompakt ve çok bantlı, kaplumbağa şekilli özgün geometride bir mikroşerit yama antenin (MPA) tasarımını ve analizini sunmaktadır. Önerilen anten, merkezi eliptik bir yama, yamanın her iki yanında simetrik olarak konumlandırılmış iki döngü yapısı ve performansı artırmak amacıyla entegre edilmiş yarım dairesel yarıklardan oluşan özgün bir konfigürasyona sahiptir. Anten, göreli dielektrik sabiti (εᵣ) 2.2 ve kayıp tanjantı (tanδ) 0.0009 olan Taconic TLY-5 alt tabaka üzerinde, 32 × 14 × 0.381 mm³ boyutlarında imal edilmiştir. Düşük kayıp özelliği ve üretim süreçleriyle uyumluluğu nedeniyle mikroşerit hat besleme yöntemi kullanılmıştır. Elektromanyetik performans değerlendirmeleri, tam dalga simülasyon yeteneklerine sahip Computer Simulation Technology (CST) Studio Suite yazılımı ile gerçekleştirilmiştir. Simülasyon sonuçları, antenin 26.29 GHz, 28.44 GHz, 34.25 GHz, 36.75 GHz, 39.17 GHz ve 42.40 GHz merkez frekanslarında verimli bir şekilde çalıştığını göstermektedir. Bu frekanslarda elde edilen kazanç değerleri sırasıyla 6.69 dBi, 9.82 dBi, 8.58 dBi, 10.44 dBi, 10.37 dBi ve 7.50 dBi olarak ölçülmüştür. Ayrıca, anten geniş bir çalışma bant genişliği, düşük yansıma kaybı, uygun Gerilim Dalgası Durum Oranı VSWR değerleri ve kararlı ışıma desenleri sergileyerek, çok bantlı 5G mmWave uygulamaları için yüksek performanslı bir çözüm sunmaktadır.

Design and Analysis of a Multiband Microstrip Patch Antenna for Millimeter Wave Applications

Öz

This study presents the design and analysis of a compact, multiband, turtle-shaped microstrip patch antenna (MPA) with a novel geometry, developed for fifth-generation (5G) wireless communication systems operating in the millimeter-wave (mmWave) frequency band. The proposed antenna features a original configuration composed of a central elliptical patch, two symmetrically positioned loop structures on either side of the patch, and integrated semi-circular slots designed to enhance performance. The antenna is designed on a Taconic TLY-5 substrate with a dielectric constant (εᵣ) of 2.2 and a loss tangent (tanδ) of 0.0009, with overall dimensions of 32 × 14 × 0.381 mm³. Due to its low-loss characteristics and compatibility with fabrication processes, a microstrip line feeding technique has been employed. Electromagnetic performance evaluations were conducted using Computer Simulation Technology (CST) software. Simulation results indicate that the antenna operates efficiently at center frequencies of 26.29 GHz, 28.44 GHz, 34.25 GHz, 36.75 GHz, 39.17 GHz, and 42.40 GHz. The corresponding gain values at these frequencies are measured as 6.69 dBi, 9.82 dBi, 8.58 dBi, 10.44 dBi, 10.37 dBi, and 7.50 dBi, respectively. Furthermore, the antenna exhibits a wide operational bandwidth, low return loss, favorable Voltage Standing Wave Ratio (VSWR) values, and stable radiation patterns, offering a high-performance solution for multiband 5G mmWave applications.
