Çift Bantlı İHA Küresel Konumlandırma Sistemi Anten Tasarımı ve Uygulaması

Abstract

Bu çalışma, insansız hava araçları (İHA) için çift bantlı yönlü mikro şerit yama anteninin tasarımı ve geliştirilmesi araştırmaktadır. Anten, GPS sisteminin L1 (1.57 GHz) ve L2 (1.22 GHz) frekans bantlarında çalışacak şekilde optimize edilmiştir. Özellikle insansız hava aracı iletişimi için kazancı ve yönlülüğü optimize ederek uzun mesafeli iletim performansını artırmak üzere tasarlanmıştır. Bu çalışmanın temel amacı, kontrollü ve yetkili ortamlarda insansız hava araçlarına karşı uygulamalar için uygun, maliyet etkin ve yerel olarak geliştirilmiş bir anten çözümü geliştirmektir. Anten tasarımı CST Studio kullanılarak simüle edilmiş ve deneysel testlerle doğrulanmıştır. Simülasyon ve deneysel ölçümleri, her iki frekans bandında da mükemmel empedans uyumu ve verimli performans göstermiştir. Anten deseni, fotolitografik teknikler kullanılarak üretim sırasında FR-4 alt tabaka üzerine hassas bir şekilde işlenmiştir. Önerilen yapı, küçük ve orta ölçekli İHA platformlarına entegrasyon için uygun, kompakt, hafif ve düşük maliyetli bir çözüm sunmaktadır.

DUAL-BAND DRONE GPS ANTENNA DESIGN AND APPLICATION

Abstract

This study investigates the design and development of a dual-band directional microstrip patch antenna for unmanned aerial vehicles (UAVs). The antenna is optimized to operate within the GPS L1 (1.57 GHz) and L2 (1.22 GHz) frequency bands. It is designed to enhance long-distance transmission performance by optimizing gain and directivity, particularly for UAV communication. The primary objective of this study is to develop a cost-effective, locally developed antenna solution suitable for counter-UAV applications in controlled and authorized environments. The antenna design was simulated using CST Studio and validated through experimental testing. The simulation and experimental measurements demonstrated excellent impedance matching and efficient performance across both frequency bands. The antenna pattern was precisely etched onto the FR-4 substrate during manufacturing using photolithographic techniques. The proposed structure offers a compact, lightweight, and low-cost solution suitable for integration into small- and medium-sized UAV platforms.
