Abstract

Ces travaux de recherche se sont effectués en collaboration avec le laboratoire de l'Intégration du Matériau au Système (IMS) à Bordeaux, le laboratoire d'Analyse et d'Architectures des Systèmes (LAAS) à Toulouse et la société STMicroelectronics à Crolles. Je tiens à remercier toutes les personnes sans qui ce travail n'aurait pas été possible. J'adresse mes plus vifs remerciements à mon directeur de thèse Professeur Eric KERHERVE, professeur à l'Université de Bordeaux, et à mon responsable industriel, Denis PACHE. Je les remercie pour avoir assuré l'encadrement de cette thèse et pour avoir fait preuve d'une grande disponibilité. Qu'ils soient remerciés de même pour la confiance qu'ils m'ont témoignée durant ce travail. J'exprime également toute ma gratitude à Messieurs Eric BERGEAULT, Professeur à l'Ecole

A Directly Matched PA-Integrated $K$-Band Antenna for Efficient mm-Wave High-Power Generation

“…Previous studies of PAIAA designs in the S-and C-bands have been conducted in [5]- [9]. In [8], a GaN high electron mobility transistor (HEMT) was used in the power amplifier design achieving a maximum output power of 38 dBm and a maximum power-added efficiency (PAE) of 59 % in C-band, in which the PA and antenna are interconnected through a harmonic tuning and impedance matching network.…”

“…Albeit that the design in [8] has good thermal capabilities, its size is rather bulky (1.9 × 1.9 × 2.1 λ 3 ). In [9] a W-band PA-antenna integrated design in silicon technology was reported, which is much more compact (0.4 × 0.4 λ 2 ), though its peak PAE is merely 6.4 % and the equivalent isotropic radiated power (EIRP) along the on-axis direction is about 3 dBm.…”

Optimized synthesis of a microwave equalizer for matching a high performance small antenna

“…The increase of both efficiency and compactness requires co-designing elementary functions (antenna, filter, amplifier...), which allows reducing interconnection stages and taking into account the interactions between individual elements [1], [2], [3], leading to optimized sub-systems. In the frame of this work, the demonstration will be given with the co-design of dual band filters together with a RHCP (right-hand circular polarization) dual-band antenna for improving the total efficiency of a receiver for GNSS (Global Satellite Navigation System) radio navigation systems.…”

Impact of small antenna on linear power amplifier performance in a co-design approach

“…This approach allows the direct connection between PA and antenna [3]. Thus, the amplifier sees directly the optimal antenna input impedance that is different from 50 Ω.…”
