Innovative Reconfigurable Systems Based on Liquid Crystals (ESA-AO6419)
We have successfully designed, manufactured and tested a beam-scanning antenna at 100 GHz, made of a parabolic main reflector and a reconfigurable reflectarray subreflector based on Liquid Crystals (LC)
Space Debris Radar
Comunidad de Madrid, S2013/ICE-3000 (2014-2018)
Several technologies were developed for a space debris detection radar. When located on space platforms such as the International Space Station or communications satellites, the radar would be used to prevent collision with dangerous objects.
“Multiple Beam Antennas based on Reflectarrays and Transmitarrays” ESA-AO8438
We have shown that a four-color multi-spot coverage (two frequencies and two polarizations) can be obtained with only two reflectarray antennas, instead of four conventional reflector.
“Advanced Multiple Antenna Subsystems for Terrestrial and Satellite Broadband Communications (TEC2016-75103-C2-1-R)”
Technological solutions have been demonstrated for antennas in two broadband communication schemes: 1) antennas on satellites to provide internet access; and 2) reconfigurable beam antennas for future 5G communications networks in millimeter waves.
“Artificial Intelligence Aided D-band Network for 5G Long Term Evolution”
Different technologies are developed and integrated (Artificial Inteligence, Maching Learning, Radiofrecuency above 100 GHz) for wideband wireless communication systems beyond 5G. We are developing at GEA an antenna, based on liquid crystal technology capable of electronically adapting indoor coverage.
ESA Innovation Triangle Initiative (ITI) Compact K/Ka band antenna feed for multi‐beam satellite communications
Development of antenna feed-chain for communications satellites with multi-beam technology in dual-band K/Ka bands.
New hybrid methods for optimizing high-frequency circuits and antenna arrays (TEC2017-83352-C2-1-P)
New hybrid methods have been implemented, which add new capabilities for efficient analysis of passive microwave circuits and antennas. Some of them are design-oriented in SIW (Substrate Integrate Waveguide) technology, since it is an emerging low cost technology.
New additive manufacturing technologies for passive devices in microwave and millimeter bands (TEC2016-76070-C32R)
New additive manufacturing techniques are changing the development model in many technology sectors. The objective of the Project has been to develop waveguide devices for space applications and power combination using Selective Laser Sintering using aluminum and copper powder mixtures. Different devices such as modal converters, polarizers and transitions have been manufactured.
STeerable BEam Reflectarray Antenna in Q, V/W bands for Gateway Links from LEO Satellites
The goal is to demonstrate electronically reconfigurable beam antenna technology in Q V/W bands, based on liquid crystal reflectarrays (LC-RA), for broadband communications using low-orbit satellite constellations.
Passive reflectarray panels are being designed to improve coverage areas in the deployment of the new millimeter-wave 5G networks.
A reconfigurable beam antenna was designed for high-performance base stations, by implementing liquid crystal technology in a reflectarray antenna.
