A water content continuous monitoring of grapevine xylem tissue using a portable low-power cost-effective FMCW radar
(IEEE, 2019)
Artículo / Artikulua,
This paper presents the real-time monitoring of a grapevine’s water content that flows up through the xylem tissue by means of a frequency-modulated continuous-wave (FMCW) radar. The application of an optimization process, ...
Advanced feeds for mm-wave antenna systems
(Springer, 2018)
info:eu-repo/semantics/bookPart,
Millimeter-wave antenna systems have traditionally required high performance feeds in order to fulfill its stringent requirements. Therefore, this goal has been achieved by corrugated horns. However, in the last years new ...
Comparison of fourth-harmonic and combined doubler/subharmonic mixer with integrated MMIC based local oscillator
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
In this paper a comparison between a fourth harmonic mixer and a combined doubler/subharmonic mixer based on Schottky diodes working at 300 GHz with MMIC Local Oscillator (LO) integrated in a single enclosing is presented. ...
Comparison of modified Soret lenses for dual band integrated detectors
(IEEE, 2020)
info:eu-repo/semantics/conferenceObject,
This paper presents the comparison of different modified Soret lenses suitable for a millimeter and submillimeterwave dualband integrated pixel detectors. The approach is based on the modification of a printed planar Soret ...
A Chebyshev transformer-based microstri-to-groove-gap-waveguide inline transition for MMIC packaging
(IEEE, 2019)
info:eu-repo/semantics/article,
The gap waveguide technology has become an alternative to millimeter- and submillimeter-wave electronic circuit packaging thanks to the loss reduction associated with its use. In this paper, a simplified design of an inline ...
Design of a groove gap waveguide to microstrip inline transition
(IEEE, 2019)
info:eu-repo/semantics/conferenceObject,
In this paper the design of an inline transition between microstrip and groove gap waveguide operating at Wband is presented. The transition consists of two sections: a
tapered microstrip line and a Chebyshev transformer. ...
A millimeter-wave 4th-harmonic Schottky diode mixer with integrated local oscillator
(MDPI, 2021)
info:eu-repo/semantics/article,
In this paper the design and experimental validation of a fourth-harmonic mixer based on Schottky diodes working around 300 GHz is presented. The main novelty of this work consists in the integration of an MMIC-based local ...
A gap waveguide-based compact rectangular waveguide to a packaged microstrip inline transition
(MDPI, 2020)
info:eu-repo/semantics/article,
In this paper two different simple to design and easy to manufacturing transitions from a microstrip to rectangular waveguide based on ridge and groove gap waveguides are studied. The first one is based on a combination ...
