Luneburg Lens

An advanced lens antenna design named for its shape, which resembles a spherical lens, and for its inventor, Rudolf Luneburg. The unique property of a Luneburg Lens is its radially varying index of refraction. This means that the lens's ability to bend or refract radio waves changes depending on the distance from the centre of the lens, but remains constant in all directions at any specific distance. When a feed, such as an antenna, is placed on or near the lens's surface, it causes the lens to emit a beam of radio waves in the opposite direction, effectively focusing the signal into a major lobe. This sophisticated design allows for highly directional signal transmission and reception, making Luneburg Lens Antennas suitable for applications requiring precise control over signal direction, such as radar and satellite communication.
