Performance Evaluation of Omni-Directional Circular UWB Disc Antenna Conformed on a Cylindrical Surface

This document is structured as follows: in Section II, the 3D deterministic model is described: we particularly focus on the specific 3D ray-tracing used for an electromagnetic

While the presence of an air gap between the patch and the ground plane enhances the radiation efficiency, the expansion of the antenna size is limited thanks to the feed line,

A discriminative subspace provides good separation between foreground and background pixels; the tracking algorithm evaluates the most discriminative subspaces in each frame and

The proposed structure consists of a circular disc monopole antenna printed on a cylindrical surface and fed by a coplanar waveguide line (CPW).. A rectangular slot antenna, excited

For example, figure 4 shows how the vibration amplitude w(t) is modified when the voltage amplitude and frequency supplied to the transducer is maintained constant,

As one can see, there is only in one case of P r = 0.01, Γ = 1.2 and liquid volume 0.8 that a big discrepancy in the critical Reynolds number was obtained (about 5%). For the case of

L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des

Even if a new design of the diplexer using the measured S-parameters of its filters is necessary to: (1) reduce the insertion losses at the lower and upper frequency
