Noise in coherently radiating periodic structures beam forming networks
(IEEE, 2022)
Contribución a congreso / Biltzarrerako ekarpena,
Following the noise wave theory, beam forming networks based on Coherently Radiating Periodic Structures (CORPS-BFN) are analysed and proven to be capable of enhancing the Signal to Noise Ratio of the system by analogically ...
New coplanar waveguide based on the gap waveguide technology
(IEEE, 2021)
info:eu-repo/semantics/conferenceObject,
A new planar waveguide, coined Inverted coplanar gap waveguide is presented. The concept of gap waveguides and parallel plate suppression between perfect magnetic and a perfect electric conductors is applied to coplanar ...
Multi-channel feedarray reflector antenna based radar concept for HRWS SAR imaging
(IEEE, 2021)
info:eu-repo/semantics/conferenceObject,
Large deployable reflector based multi-channel antenna systems are a key component of next generation SAR missions as they allow implementing multi-beam imaging capabilities and provide an efficient way to overcome the ...
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 ...
Characterization of 3D-printed choke horn antenna for 5G backhaul applications
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
The 200 and 320 GHz frequency band constitutes an interesting window with approximately constant attenuation, which could potentially have applications in the area of ultrahigh-capacity wireless links. The user's demand ...
