UWB, Non Dispersive Radiation From the Planarly Fed Leaky Lens Antenna— Part 1: Theory and Design
article
Abstract—An efficient directive antenna is described that can be used to realize essentially non dispersive links over extremely
large bandwidths. The antenna is a significantly enhanced version of previously proposed Leaky Lens antennas that use a frequency
independent leaky slot radiation mechanism. A theoretical breakthrough now allows the use of this mechanism also in the presence
of purely planar structures. This step allows the realization of the feed of a leaky lens antenna in a unique planar structure that is then
glued to a standard circularly symmetric elliptical dielectric lens, as integrated technology requires in the mm and sub-mm wave domains.
The first part of this sequence deals with a theoretical breakthrough, the consequent antenna concept and a description of the
basic physical mechanisms inside and outside the lens antenna. It is shown that Leaky Lens antennas have the potential to be used to
realize antenna links over bands exceeding a decade with minimal dispersion, high efficiency and high directivity. The second part of
this sequence deals with the demonstration of these claims via the measurement of two prototypes
