Lunar Communications
Moon exploration is one of the objectives of ESA and other agencies such as NASA or JAXA for this decade. EOSOL is committed with technology development for new challenges as this one. For this reason, the team has been involved in last years in different initiatives for needed antenna technology development for the exploration of our natural satellite. In collaboration with other European entities, EOSOL is currently working under an ESA project in the development of a set of antennas to enable wireless communications in lunar caves and cavities. This is a great challenge due to the harsh conditions in the lunar environment.
Our goal is to develop compact and lightweight antennas for assets capable of operating on lunar surface and inside lunar caves at Wi-Fi frequencies (2.4 or 5 GHz).
Omnidirectional Patch Arrays
This new line of all-metal Omnidirectional Patch Array antennas are designed to be integrated into the mast of a rover/asset giving full coverage on the lunar surface with an outstanding coverage and gain performance.
Two options are available, S-band and C-band antennas. We currently have a first line of prototypes, and the first antennas will be ready by the end of 2025.

Pagoda Antenna
The ANT-PAGODA-2.4-2.5 is a WiFi Band Circular Polarized PCB Antenna with a matching value better than 13 dB. Interactions between both internal PCB discs and their support structures create a radiation pattern with omnidirectional coverage along the 2.4GHz WiFi frequency band.
This antenna has been designed and tested under conditions similar to those on the lunar surface.
