Harmonical characterization of a microstrip bend via the finite difference time domain method
TL;DR: In this article, a 90 degrees microstrip bend is characterized using a time-frequency method based on the finite-difference-time-domain (FDTD) method, where the time evolution of the currents generated by FDTD are Fourier transformed to lead to S-parameters and the radiated powers characteristic of the microstrip bends.

A Novel Antenna for Transient Applications in the Frequency Band 300 MHz – 3 GHz: The Valentine Antenna
Jean-Christophe Diot,P. Delmote,Joël Andrieu,Michèle Lalande,Valérie Bertrand,Bernard Jecko,S. Colson,R. Guillerey,M. Brishoual +8 more
TL;DR: In this paper, a new ultrawideband (UWB) antenna called the Valentine antenna is proposed for transient UWB radar applications, which is composed of curved metallic strips and radiates ultrashort pulses in the frequency band 300 MHz - 3 GHz with very low dispersion, high gain and a low cross-polarization in the axial direction.
Journal ArticleDOI
An Original Antenna for Transient High Power UWB Arrays: The Shark Antenna
TL;DR: In this paper, a novel ultrawideband (UWB) antenna, called the Shark antenna, and designed especially for transient applications is proposed in order to obtain a high power UWB pulse radiation source through the frequency band [800 MHz-8 GHz].
Journal ArticleDOI
An ultra wideband impulse optoelectronic radar: rugbi
Michèle Lalande,Jean-Christophe Diot,Stéphane Vauchamp,Joël Andrieu,Valérie Bertrand,Bruno Beillard,Bertrand Vergne,Vincent Couderc,Alain Barthélémy,D. Gontier,R. Guillerey,M. Brishoual +11 more
TL;DR: In this article, an ultra wideband radar system based on coherent emission of an ultra-wideband antenna array using photoconductive switching devices is proposed, where the triggering process is obtained by the excitation of semiconductor samples in linear mode using a picosecond laser source.
Journal ArticleDOI
High Pulsed Power Sources for Broadband Radiation
Baptiste Cadilhon,Laurent Pecastaing,T. Reess,A. Silvestre de Ferron,P. Pignolet,S. Vauchamp,Joël Andrieu,Michèle Lalande +7 more
TL;DR: In this paper, the authors describe the design and production of two autonomous ultrawideband (UWB) radiation sources consisting of a high-gain broadband antenna that is driven by one of two sub-nanosecond pulsed power sources.
