Design and Modeling of Metamaterial-Based Antenna Arrays for Nanosatellite Communication Systems
The design and modeling of compact antenna arrays based on metamaterials for nanosatellite communication systems is presented. The main objective is to optimize performance at 2.45 GHz (S-Band).

I28-R145-217_oai2026-02-11 Hemsy, Axel Ise, Juan Eduardo Cabrera, Miguel Angel Fagre, Mariano 2025-12-15 The design and modeling of compact antenna arrays based on metamaterials for nanosatellite communication systems is presented. The main objective is to optimize performance at 2.45 GHz (S-Band). As a first step, a single coaxially fed antenna was designed on a Rogers RO4350B substrate (0.76 mm thick, εᵣ = 3.48). A unit cell with Minkowski fractal geometry was incorporated into the ground plane, and two opposite corners of the patch were truncated to induce right-hand circular polarization. Different antenna arrays were designed in 1×2 (47 × 100 mm), 1×4 (47 × 165 mm), and 2×2 (75 × 80 mm) configurations, all with the same thickness of 0.76 mm. The feeding networks were implemented using Wilkinson power dividers. These arrays enabled an increase in gain to 5.0 dBi, 7.3 dBi, and 5.9 dBi, as well as an improvement in axial ratio, while maintaining efficiencies between 79% and 87%. The useful bandwidths obtained (VSWR < 2, S₁₁ < -10 dB, axial ratio < 3 dB) were 20.7 MHz, 21.4 MHz and 31.1 MHz. The compact dimensions allow integration with the structure and subsystems onboard a CubeSat: the 1×2 and 2×2 arrays are compatible with a 1U format, while the 1×4 can be integrated into a 2U format. Se presenta el diseño y modelado de arreglos de antenas patch compacta basada en metamateriales, destinada a sistemas de comunicación para nanosatélites. El objetivo principal es optimizar el desempeño a una frecuencia de 2.45 GHz (Banda S). Como primer paso, se diseñó una antena individual con alimentación coaxial sobre un sustrato Rogers RO4350B (espesor de 0.76 mm, εᵣ = 3.48). En el plano de tierra se incorporó una celda unitaria con geometría fractal tipo Minkowski, y se truncaron dos esquinas opuestas del parche para inducir polarización circular derecha. Se diseñaron diferentes arreglos de antenas en configuraciones 1×2 (45 × 85 mm), 1×4 (48 × 155 mm) y 2×2 (75 × 85 mm), todos con el mismo espesor de 0.76 mm. La alimentación se realizó mediante divisores de potencia tipo Wilkinson. Estos arreglos permitieron aumentar la ganancia a 5.1 dBi, 5.2 dBi y 5.8 dBi, y mejorar la relación axial, manteniendo eficiencias entre el 71% y el 78%. Los anchos de banda útiles obtenidos (ROE < 2, S₁₁ < -10 dB, relación axial <3 dB) fueron de 22 MHz, 39 MHz y 27 MHz. Las dimensiones compactas permiten su integración con la estructura y los subsistemas a bordo de un CubeSat: los arreglos 1×2 y 2×2 son compatibles con un formato de 1U, mientras que el 1×4 puede integrarse en un formato de 2U. application/pdf text/html https://elektron.fi.uba.ar/elektron/article/view/217 10.37537/rev.elektron.9.2.217.2025 eng FIUBA https://elektron.fi.uba.ar/elektron/article/view/217/399 https://elektron.fi.uba.ar/elektron/article/view/217/403 Derechos de autor 2025 Axel Hemsy, Juan Eduardo Ise, Juan Eduardo Ise, Miguel Angel Cabrera, Juan Eduardo Ise, Mariano Fagre, Miguel Angel Cabrera, Miguel Angel Cabrera, Mariano Fagre, Mariano Fagre Elektron Journal; Vol. 9 No. 2 (2025); 94-100 Revista Elektron; Vol. 9 Núm. 2 (2025); 94-100 Revista Elektron; v. 9 n. 2 (2025); 94-100 2525-0159 2525-0159 nanosatellite antenna array metamaterial nanosatélite arreglo de antenas metamaterial Design and Modeling of Metamaterial-Based Antenna Arrays for Nanosatellite Communication Systems Diseño y modelado de arreglos de antenas basado en metamateriales para sistema de comunicación de nanosatélite info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=217_oai |
