Luneburg lens Antenna
8.2 GHz-12.5 GHz Luneburg lens Antenna
Antennas Cover From 2GHz to 110GHz
Luneburg lens antenna is a spherical dielectric lens antenna, which focuses microwaves to the focal point through dielectric. Luneburg lens antenna is widely used in microwave, millimeter wave, mobile communication, satellite communication and radio astronomy due to its high gain, low profile and multi-feed multi-beam operation.
The distribution has sphere symmetry, which makes any point on the Luneburg lens sphere the focal point of the lens sphere. Therefore, as long as the position of the antenna feed on the spherical surfaces controlled, the electromagnetic radiation beam can be directed in any direction, and there is no defocus problem as the position of the feed on the spherical surface changes.
Due to the medium distribution characteristics of the lens, the antenna is relatively insensitive to the frequency band of electromagnetic waves, so the frequency band can be very wide.
Customize Luneburg lens antenna are offered for the frequency range of 2 to 110 GHz. The standard gain value and corresponding half power beam width a 8.2 GHz-12.5 GHz is 15 dB and 8 degrees.
