A Luneburg Lens Antenna is a spherically symmetric gradient-index focal point. An ordinary Luneburg lens's refractive list n diminishes radially from the center to the external surface. Luneburg lens is a new generation of antennas. The centering properties of the Luneburg focal point can be accomplished through a boundless number of refractive-index arrangements.
Luneburg lens is utilized in utilizing different clusters with the ultra-broadband capability and wide seeing within the microwave radio range. RFecho Luneburg lens has the frequency range from 1.7GHz to 40GHz where Gains are 15, 20, and Return Loss is less than – 20 (dB).
