Optimizing Antenna Activation for Even Power Distribution in Multi-Beam Satellite Systems Using Genetic Algorithm
Juan Andrés Vasquez-Peralvo, Aral Ertug Zorkun, Jorge Querol +5
Recent advancements in onboard satellite communication have significantly enhanced the ability to dynamically modify the radiation pattern of a Direct Radiating Array, which is ess…
Exploring Radial Symmetry on Phased Arrays Using Particle Swarm Optimization
Arkadii Kazanskii, Juan Andres Vasquez-Peralvo, Symeon Chatzinotas
Phased antenna arrays enable dynamic beam shaping, which is essential for Non-Geostationary (NGSO) satellite communications where efficient beam distribution is important. This stu…
3D Printed Discrete Dielectric Lens With Improved Matching Layers
Juan Andrés Vásquez-Peralvo, José Manuel Fernández-González, Thomas Wong
This paper presents a non-zoned discrete dielectric lens comprising two or three matching layers to reduce the 50-110 GHz frequency range reflections. Based on Chebyshev and binomi…
Satellite Swarms for Narrow Beamwidth Applications
Juan A. Vásquez-Peralvo, Juan Carlos Merlano Duncan, Geoffrey Eappen +1
Satellite swarms have recently gained attention in the space industry due to their ability to provide extremely narrow beamwidths at a lower cost than single satellite systems. Thi…
