Cylindrical Luneberg Lens Antenna | Antenna Magus

Image of the Cylindrical Luneberg lens antenna.

The conventional spherical Luneburg lens can be redesigned using a coordinate transformation to change the size and shape for integration into planar microwave applications - resulting in a cylindrical lens shape.

The cylindrical Luneburg does not achieve gains higher than 22 dBi as easily as the spherical Luneburg lens and also has reduced performance i.t.o. side lobe level, front-to-back ratio and return loss. By moving the feed parallel to the lens, the beam can be steered. Steering the beam may, however, cause a drop in the gain and a further increase in side lobe level.
