LEO satellite antennas must provide several beams at the same time up to Ka-band over a large scanning angle (up to ±60°). For this reason, high performance radiating elements and beamforming circuitry becomes crucial for the development of new constellations. This paper outlines the challenges and limitations of both waveguide-based and Vivaldi-based solutions and their impact on the beam-formed patterns.

Abstract
LEO satellite antennas must provide several beams at the same time up to Ka-band over a large scanning angle (up to ±60°). For this reason, high performance radiating elements and beamforming circuitry becomes crucial for the development of new constellations. This paper outlines the challenges and limitations of both waveguide-based and Vivaldi-based solutions and their impact on the beam-formed patterns.File in questo prodotto:
