Dual-Band Microstrip Patch Antenna Design for High-Speed Communication Systems

Öz

In this study, a dual-band microstrip patch antenna was designed for high-speed communication systems. To meet the increasing demand for data transmission, a compact, low-profile, and PCB-based structure was targeted. By optimizing the size and position of the slots on the patch, dual-band operation was achieved at 4.73 GHz and 5.23 GHz frequencies. CST Studio Suite analyses showed that the antenna achieved a return loss below -10 dB, a VSWR value under 2, and a gain of 2.86 dBi. Radiation analysis revealed that the modification enhanced antenna directivity and reduced side lobe levels. The results indicate that the proposed antenna offers better impedance matching and stable dual-band performance compared to the conventional patch antenna. With its compact structure and low cost, it is a suitable candidate for WLAN and sub-5G band applications.

Yüksek Hızlı Haberleşme Sistemleri İçin Çift Bant Mikroşerit Yama Anten Tasarımı

Öz

Bu çalışmada, yüksek hızlı haberleşme sistemleri için çift bantlı mikroşerit yama anten tasarımı yapılmıştır. Artan veri iletim ihtiyacına yönelik olarak kompakt, düşük profilli ve PCB tabanlı bir yapı hedeflenmiştir. Yama üzerinde açılan yarıkların boyut ve konumları optimize edilerek 4,73 GHz ve 5,23 GHz frekanslarında çift bantlı çalışma sağlanmıştır. CST Studio Suite analizleri sonucunda antenin -10 dB altında geri dönüş kaybı, 2’nin altında VSWR ve 2,86 dBi kazanç değerlerine ulaşıldığı görülmüştür. Radyasyon analizi, modifikasyonun antenin yönlülüğünü artırdığını ve yan lob seviyelerini azalttığını göstermiştir. Elde edilen sonuçlara göre, tasarlanan anten klasik yama antene kıyasla daha iyi empedans uyumu ve kararlı çift bant performansı sunmaktadır. Kompakt yapısı ve düşük maliyeti sayesinde WLAN ve 5G alt bant uygulamaları için uygun bir adaydır.
