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 ...
Hexagonal CORPS-BFN to feed OLAF SAR instrument
(IEEE, 2021)
info:eu-repo/semantics/conferenceObject,
The concept of Coherently Radiating Periodic Structures-based Beam Forming Networks is applied to feed OLAF (OverLapped SubArray Fed) antenna for SAR Instrument at L-Band. The proper feeding of this system requires the ...
New hexagonal CORPS-BFN for multibeam antenna applications
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
This work presents a new topology of a Coherently Radiating Periodic Structure - Beam Forming Network (CORPS-BFN) and its application for multibeam systems. A unit cell, consisting of a transition from a coaxial input to ...
