THz communications systems at carrier frequencies above 200 GHz are the key to enable next-generation mobile communication networks with 100 Gbit/s wireless data rates. One of the key questions is, which carrier frequency ... -
A Chebyshev transformer-based microstri-to-groove-gap-waveguide inline transition for MMIC packaging
Pérez Escudero, José Manuel ; Torres García, Alicia E. ; Gonzalo García, Ramón ; Ederra Urzainqui, Íñigo (IEEE, 2019)
Artículo / Artikulua
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 300 ghz combined doubler/subharmonic mixer based on schottky diodes with integrated mmic based local oscillator
Pérez Escudero, José Manuel ; Quemada Mayoral, Carlos ; Gonzalo García, Ramón ; Ederra Urzainqui, Íñigo (MDPI, 2020)
Artículo / Artikulua
In this paper the design and experimental characterization of a combined doublersubharmonic mixer based on Schottky diodes which uses a 75 GHz MMIC based local oscillator is presented. This solution integrates in the same ... -
A millimeter-wave 4th-harmonic Schottky diode mixer with integrated local oscillator
Pérez Escudero, José Manuel ; Quemada Mayoral, Carlos ; Gonzalo García, Ramón ; Ederra Urzainqui, Íñigo (MDPI, 2021)
Artículo / Artikulua
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 ... -
Modified Soret lenses for dual band integrated detectors at submillimetre and millimetre wavelengths
Torres García, Alicia E. ; Pérez Escudero, José Manuel ; Gonzalo García, Ramón ; Ederra Urzainqui, Íñigo (IEEE, 2020)
Artículo / Artikulua
This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photonic crystal (PC) slab to a resonant cavity that effectively ... -
Moisture content estimation models of flour matrices in the 67-110 GHz frequency range using a nondestructive and contactless monitoring system
Quemada Mayoral, Carlos ; Ederra Urzainqui, Íñigo ; Beruete Díaz, Miguel ; Gonzalo García, Ramón ; Iriarte Galarregui, Juan Carlos (IEEE, 2023)
Artículo / Artikulua
This work addresses the lack of moisture content estimation models for food products in the millimeter-wave frequency range and showcases the potential of this range for designing compact, cost-effective, and in-line food ... -

A simplified design inline microstrip-to-waveguide transition
Ederra Urzainqui, Íñigo ; Gonzalo García, Ramón ; Pérez Escudero, José Manuel ; Torres García, Alicia E. (MDPI, 2018)
Artículo / Artikulua
A simplified design of an inline transition between microstrip and rectangular waveguide is presented in this paper. The transition makes use of a dielectric filled rectangular waveguide (DFRW) as an intermediate step, ... -
A water content continuous monitoring of grapevine xylem tissue using a portable low-power cost-effective FMCW radar
Quemada Mayoral, Carlos ; García González, Cebrián ; Iriarte Galarregui, Juan Carlos ; Marín Ederra, Diana ; Gastón Beraza, Diego; Miranda Jiménez, Carlos ; Gonzalo García, Ramón ; Maestrojuán Biurrun, Itziar ; Santesteban García, Gonzaga ; Ederra Urzainqui, Íñigo (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, ...
