Luneberg Lens Principle > Presentation |
| THE LÜNEBERG LENS PRINCIPLE |
 |
| The Luneberg lens is a dielectric sphere with a permittivity varying with the distance from the center. This property allows a good focalisation of the microwave beams in a focal point located at the peripheral of the lens. The lens can then be used as a reflector (with a metallization) or as emission or reception antenna (with one feed or more). |
|
| THE ADVANTAGES OF A LÜNEBERG REFLECTOR |
• Considerable increase in RCS (Radar Cross Section) for
any systems with little or no RCS.
• Homogeneous response inside a wide angle. |
|
|
| THE ADVANTAGES OF A LÜNEBERG ANTENNA |
• Reduced size
• High reception performance / Extremely large bandwidth
• Generation of multiple beams, aimed in different directions /
multi-beam antennae |
