Abstract

National audience; Cet article présente une technique de synthèse systématique pour les multiplexeurs couplés par manifold. Cette technique fournit d'une part la structure de manifold qui empêche l'apparition des pics du manifold et, d'autre part, le modèle circuit des filtresà utiliser dans la conception. Finalement un exemple est présenté.

Abstract

This work presents advances on the development of a resonant radiator, obtained as the augmentation of a conventional Impulse Radiating Antenna (IRA) with a Frequency Selective Surface (FSS), in the L-band. An improved passband-type FSS is obtained by exploring the Multiple Split Ring Resonators (MCSRR) unit cells to obtain a higher Q-factor radiator. The effects of a multiband and of a tunable FSS’s are also studied and verified via simulations. A variety of applications are enabled by modifying the UWB waveform from the IRA into a damped sinusoidal from the combined radiator like IEMI testing, hardening of infrastructures, cloaking of wide aperture radiators, among other. The system analysis methodology can also be applied to other FSS geometries, or the combinations of various of them.
