Antenna

THE  LUNEBERG ANTENNA

Luneberg lenses are used in microwave communication.

Luneberg lenses can be excited by one or several feeds, providing multi-feed antennas with extremely high directivity and high theoretical gain G, equivalent to the gain of a parabolic antenna of similar diameter.

Application :
-Satellite communication


Satellite reception

Hemispherical antenna for satellite r
eception

Fixed antenna for satellite reception

Satellite link for mobile vehicle
(air/land/maritime)

APPLICATIONS FOR COMMUNICATION SYSTEMS WITH GEOSTATIONARY SATELLITES

FIXED ANTENNA
use of a hemispherical lens on an overall building plan by pointing at several satellites, for the general public.
- television reception – Ku band
- multimedia application – Ka band


APPLICATIONS FOR COMMUNICATION SYSTEMS WITH A CONSTELLATION OF SATELLITES IN LOW EARTH ORBIT
