Spot-Focusing Lens Horn Antenna
The spot-focusing lens horn antenna uses phase correction to achieve excellent focusing performance with minimum antenna size, so that the beams converge at the designed focus to form a focal spot. It supports both linear and circular polarized waveforms, and the focal length and spot size can be customized. The spot-focusing lens horn antennas are especially useful when focusing beam is required with short focal length. When the focal spots of the two spot-focusing lens antennas are coincident, the transmission loss between the two antennas is minimal. Therefore, these antennas are widely used in the field of free-space method material characterization testing to study the microwave transmission and reflection properties of target substances.
