Diseño y fabricación de una antena plana para cámaras de imagen en el rango del terahercio
(2010) Rebollo Mugueta, Ainara; Ederra Urzainqui, Íñigo; Escuela Técnica Superior de Ingenieros Industriales y de Telecomunicación; Telekomunikazio eta Industria Ingeniarien Goi Mailako Eskola Teknikoa; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
Las antenas utilizadas, actualmente, en nuestra cámara de imágenes a frecuencias de terahercio, son las antenas de bocina. Estas antenas proporcionan sistemas de captación de imágenes de gran tamaño, y además, complican su fabricación y diseño. Por esta razón, recientemente, ha aumentado la investigación en el desarrollo de antenas en tecnología plana, debido a su peso ligero, reducidas dimensiones y simplicidad de integración en el sustrato del receptor de THz, con la capacidad de mantener su ancho de banda. El objetivo de este proyecto es el diseño de una antena plana, en concreto, de una antena Vivaldi a 94GHz sobre el sustrato utilizado en los receptores MSi102 de la solución MMIC para la cámara de imagen a frecuencias de THz. Este sustrato en el Rogers Ultralam® 3850/3908 con grosor 0.1mm. El método seguido en el proyecto para el diseño de la antena Vivaldi a 94GHz es partir de un prototipo de antena Vivaldi a 10GHz. Para ello, necesitaremos optimizar un diseño para el prototipo y una vez que lo hayamos testado mediante una comparación con la medición del prototipo real, fruto de la fabricación, realizaremos el diseño de la antena Vivaldi a 94GHz a partir del prototipo optimizado mediante la técnica del escalado.

Corrugated horn antenna noise temperature characterisation for the NRL water vapor millimeter-wave spectrometer project
(2011) Teniente Vallinas, Jorge; Gómez, R.M.; Maestrojuán Biurrun, Itziar; Rebollo Mugueta, Ainara; Gonzalo García, Ramón; Río Bocio, Carlos del; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
In this paper the antenna noise temperature for two different corrugated horn antennas (old model and new model) for NRL WVMS is being characterized. The whole optical system will be simulated with Ticra’s GRASP software, and the corrugated horns with Mician μWave Wizard software. Spherical wave expansion from Mician μWave Wizard will be exported to Ticra’s GRASP to connect both results.

Optimization of a pin surface as a solution to suppress cavity modes in a packaged W-band microstrip receiver
(IEEE, 2014) Rebollo Mugueta, Ainara; Gonzalo García, Ramón; Ederra Urzainqui, Íñigo; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
A pin surface structure has been used in the upper metal plate of a packaged W-band RF front-end receiver in order to suppress the propagation of unwanted modes. A full parametric analysis of the periodic structure within the irreducible Brillouin zone has been carried out in order to understand the behavior of the pin surface and determine the optimum dimensions for its operation in the full W-band. Resonances suppression has been demonstrated in the W-band both in simulation and experimentally.

Development of an auto-calibrated receiver in planar technology at millimetre-wave frequencies
(2015) Rebollo Mugueta, Ainara; Ederra Urzainqui, Íñigo; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
This dissertation deals with the development of an auto-calibrated receiver at W-band for Passive Millimetre-Wave imaging applications. The proposed receiver has three main characteristics. Firstly, its differential configuration allows performing the internal calibration of the system. As opposed to total power receivers, this configuration reduces the effect of receiver instabilities. Secondly, it is entirely built in planar technology. As a consequence, a broadband planar antenna could be included in the same substrate resulting in a compact and light receiver. And finally, the W-band auto-calibrated receiver is based on a direct detection scheme which makes it simpler extending the number of receivers. Moreover, it uses commercially available low loss dielectric substrate and MMIC devices such as low noise amplifiers and detectors. This dissertation tackles all the required steps for the development of the W-band auto-calibrated receivers. Firstly, the theoretical analysis of the differential configuration was done highlighting its main advantages. Once this configuration was analyzed, the design of its W-band planar components, i.e. a quadrature hybrid coupler, WR10 waveguide to microstrip transition based on an E-plane probe and Vivaldi antenna fed by a slotline to microstrip transition, and the selection of the MMIC devices, i.e. low noise amplifier, reference load and detector, were carried out. Then, the analysis of the real configuration of the receiver was accomplished, identifying the effect of each component on its performance. After finishing the design, the proposed components were characterized. This process includes, as first step, the analysis of the dielectric constant and loss tangent of several substrates in order to determine their properties in the W-band. Afterwards, an inline WR10 waveguide to microstrip transition, required to characterize multiple planar devices at W-band frequencies with waveguide based measurement equipment was designed, manufactured and validated. This was the basic block used to characterize the manufactured components. Once the performance of these components was verified, the packaging metal block was designed and manufactured. It includes an innovative solution, based on a pin surface, in order to avoid the propagation of undesired modes, which can penalize the performance of the planar receiver. The experimental results prove the suppression of these cavity modes. Finally, the complete W-band auto-calibrated receiver was assembled and characterized in terms of input reflection coefficient, dynamic range, RF-DC response, effective bandwidth and equivalent noise temperature.
