Study of optical vortices in lens antenna

This work presents an analysis of optical vortices produced by homogeneous dielectric lens antenna with hyperbolic profiles in the millimeter waveband. The use of dielectric lenses can substantially improve the antenna parameters, especially the flatness of the radiated waves and the gain of the ant...
