Monolithic Microwave Integrated GaAs Electromagnetically-Coupled Antenna

Marjorie Grzeskowiak, Jean Vindevoghel

Monolithic antenna on GaAs to be used in miniature active sensors is presented. After a first study of technological processes and the characterisation of various substrates in K-band, the feasibility of an antenna, operating in K-band, electromagnetically-coupled and integrated on GaAs by…

Conception of integrated polymer antennas for characterisation of dielectric properties

Marjorie Grzeskowiak, Philippe Descamps, Jean Vindevoghel

To design microstrip antennas, we have to know the relative permittivity and losses of the antenna substrate. In the case of polymers, these electrical properties are given at 1 MHz by the constructor and are not the same ones at other frequencies. We decide to take this problem back to front and…

Giant magnetostriction (GMS) of TbFe monolayer with improved field-induced anisotropy and sensitivity

Henri Le Gall, Jamal Ben Youssef, J. Ostorero, Nicolas Tiercelin, Philippe Pernod, Vladimir Preobrazhensky

Giant magnetostriction, (GMS), reported until now in thin films using rare earth-transition metal RM/sub 2/ (R=Tb, Sm, and M=Fe, Co) compounds, presents in most cases an isotropic or quasi-isotropic magnetoelastic (ME) behavior. A large change of the ME coefficient b under the lowest possible…

Giant magnetostriction thin films for multi-cantilever micro-structures driving

Nicolas Tiercelin, Philippe Pernod, Vladimir Preobrazhensky, Henri Le Gall, Jamal Ben Youssef, Patrick Mounaix, Didier Lippens

First results on the realisation of a micrometer GaInAs multi-cantilever structure (50×30×1 μm3 each) driven by amorphous TbFe magnetostrictive thin films are presented. Magneto-elastic properties of the cantilevers were studied by dynamic excitation methods. A resonance of the bimorph cantilevers…

Uniformity improvement of linear power pHEMTs using a very high selective wet etching

X. Hue, B. Boudart, B. Bonte, Y. Crosnier

The realization and characterization of Al0.22Ga0.78As/In0.22Ga0.78As/GaAs multifinger linear power pHEMTs, using a citric acid selective wet etching for the gate recessing, are reported. A very high uniformity for both the drain current and pinch-off voltage values have been obtained. The…
