AB - A broadband and low beam squint anisotropic
magneto-dielectric 2D leaky-wave antenna excited by a vertical
electric source is presented. A comparison of the TM dis-
persion behavior of the structure for Drude/Lorentz dispersive
anisotropic and an isotropic non-dispersive grounded slabs is
performed. The isotropic slab is restricted to leaky-wave pointing
angles near endfire with very low radiation performance due
to the inherent endfire radiation null caused by the slab. As a
result, its radiation is dominated by the space-wave, which leads
to low directivity and beam scanning incapability. In contrast,
the anisotropic meta-substrate provides a highly directive and
efficient 2D leaky-wave radiation with great design flexibility.
At its lower frequencies, it provides narrow-band full-space
conical-beam scanning while at higher frequencies, it enables
a designable angle fixed-beam with low-beam squint radiation.
This antenna may find applications in broadband point-to-point
communication and radar systems.
