Other characteristics and options:
Luneberg lenses are used in microwave communication.
Luneberg lenses can be excited by one or several feeds, providing multi-feed antennae with extremely high directivity and high theoretical gain G, equivalent to the gain of a parabolic antenna of similar diameter.
- On-board antenna: plane, train, boat, car, ...
- Microwave communication, high outflow Internet.
- Communication toward several fixed or mobile antennae (satellites...)
- Land communication relay station.
