Hyperbolic lens antenna in groove gap waveguide technology at sub-millimeter waves
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a flat hyperbolic lens antenna using Groove Gap Waveguide (GGW) technology is designed at 300 GHz. A GGW horn antenna is used to feed the metamaterial lens placed in a parallel plate waveguide (PPW), in order ...
Design of a planar meta-surface based on dipoles and wires for antenna applications
(2006)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, the design of a planar meta-surface based
on dipoles and wires is presented. The unit cell is formed
by three independent layers, which contain two parallel
dipoles and one wire. The behaviour of these ...
