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 ...
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 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 ...
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 ...
