The design of multi-beam Luneburg lens antenna operating in frequency band 1710 - 2690 MHz is presented. The developed antenna provides 12 independent beams covering the sector of 120°. The dual-polarized radiator providing two orthogonal polarizations has been developed. Being located on the focal surface of the Luneburg lens the radiator provides pattern with 10 dB beam width from 8 to 12 degrees. The tilt is provided by the mechanical movement of each radiator along the focal surface. The isolation between two orthogonal polarizations as well as between all channels is better than -28 dB.
