Antennas

Typically used for GPS applications or TTC subsystems due to its wide angle coverage:
- Low Earth Orbit (LEO) Satellites
- Geostationary Communication Satellites
- ATV Supply Vehicle for International Space Station
- Europe’s global navigation satellite system: Galileo (IOV and FOC Phases)
- VEGA ESA’s series of small launchers
- Intermediate eXperimental Vehicle, IXV
The design can be customized (Radiation performance and/or mechanical configuration)

Baseline supplier for the TTC subsystems in the main platforms of geostationary telecom satellites in Europe
On board Low Earth and Medium Earth Orbit constellation of satellites
- Globalstar-2, O3B, Iridium NEXT
Used in X Band for TTC subsystems in scientific missions
- HERSCHEL, PLANCK, ROCSAT, BEPI COLOMBO, LISA PATHFINDER, GAIA, EXOMARS, SOLAR ORBITER
Qualified designs in C Band, X Band, Ku Band and Ka Band

Widely present in the TTC subsystems of US satellite platforms
Dual Band operation (Transmit / Receive) with a single antenna with stacked radiators
Toroidal pattern around longitudinal axis with Lineal or Circular polarization
Qualified designs for wide band operation

Used for data downlink from Low Earth Orbit (LEO) satellites in Earth Observation missions
Isoflux Gain Pattern with a gain figure up to 6.75 dBi at 63º from boresight
Qualified design on board wide amount of Earth Observation missions
Support structure is customizable for the mission requirement

Global coverage in low bands (UHF, L and S Bands), where conical horns become too big
Gain pattern performance can be optimized in response to particular requirements
Standard Gain performance is G > 17 dBi or G > 13 dBi for EoC |q| < 9º
Low Axial Ratio within EoC (AR < 1 dB)

Transmit and Receive Horn Antennas in all bands
- L Band, S Band, C Band, X Band, Ku Band, K Band and Ka Band
Custom Feed Network
- Linear / Circular Polarization (OMT, Septum polarizer…)
