The Luneburg Antenna

Luneberg lens is a new generation of antennas that has been developed since first being proposed in 1944. In the last few years ithas developed applications in Microwaves, Communications and Telescopes area.

The Luneburg lens is a spherical lens generally having a gradient of decreasing refractive index radially out from its center. The focusing properties of the Luneburg lens can be achieved through an infinite number of refractive-index solutions.

Applications

SKA. Proposals utilising multiple arrays with ultra-broadband capability and wide viewing in the microwave radio spectrum are proposed. 

Arecibo. A Luneburg antenna lens configured as a Retroreflector (developed by the CSIRO) is configured a subreflector feedpoint as a replacement for the 430Mhz line feed at Arecibo.
