Analysis of a multiband monopole handset antenna combined with a slotted ground plane.
(2013-01-01)
Article
Accés restringit per política de l'editorialThe ground plane of a handset device plays an importants role in radiations process. As a consequence, thorugh a ground plane modification, it is possible to obtain a multiband performance while keeping small antenna dimensions. -
Experimental demonstration of multi-band upstream in statistical OFDM-PONs and comparison with digital subcarrier assignment
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialA multiband subcarrier allocation scheme is demonstrated for the uplink in a statistical OFDM-PON. Performance achieved is similar to digital subcarrier allocation, with the significant advantage of a lower transmitter complexity. -
MIR: the microwave interferometric reflectometer, a new airborne sensor for GNSS-R advanced research
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialThe use of Global Navigation Satellite Signals (GNSS) in reflectometric applications (GNSS-R) is highly extended in remote sensing applications, such as sensing sea state, soil moisture or ice layer characterization. There ...
