Basic Principles of Fresnel Antenna Arrays
The classical Fresnel lens is different from the shaped dielectric lens in that the
phase transforming surface is broken down into Fresnel zones, or concentric
circular sections. Although the sections have discontinuities between them, each
...

Antennas And Wave Propagation
It can be shown that the dielectric lens used as antenna is identical to the optical
lens by using ray analysis method of geometrical optics. Consider that a isotropic
point source is placed at focal point say O. This is acting as primary antenna.

Antenna And Wave Propagation
2) For larger bandwidth requirements, unstepped dielectric lens are used
because its shape is not dependent on wavelength. For narrow bandwidth
applications, the dielectric lens antennas are used. 3.30 Non-Metallic Dielectric

Modern
Lens Antennas for Communications Engineering
In most applications, the dielectric lens will be coupled with a quasi-optical
system, and Figure 4.17 shows the dielectric lens coupled to an objective lens. If
the Gaussian beams emanating from the dielectric lens are well characterized,
then ...

9-8.1 Coma-Free Axisymmetric Dielectric Lens [9] The design of the coma-free
axisymmetric antenna reduces to the numerical solution of a differential equation
with side conditions to produce a collimated beam and satisfy the Abbe sine ...

Since the double-slot antenna used in Figure 6.13 launches a nearly perfect
fundamental Gaussian beam into the dielectric lens, the “Gaussicity'' can also be
thought of as a measure of the aberrations introduced by the lens. When
