Synthesis of sparse arrays with focused or shaped beampattern via sequential convex optimizations

Benjamin Fuchs

An iterative procedure for the synthesis of sparse arrays radiating focused or shaped beampattern is presented. The algorithm consists in solving a sequence of weighted l(1) convex optimization problems. The method can thus be readily implemented and effic ...

Example of data telemetry for biomedical applications: an in vivo experiment

Juan Ramon Mosig, Anja Skrivervik, Yann Barrandon, Eric Meurville, Jean-François Zürcher, Francesco Merli, Léandre Bolomey, François Gorostidi, Benjamin Fuchs

This letter describes a data telemetry biomedical experiment. An implant, consisting of a biometric data sensor, electronics, an antenna, and a biocompatible capsule, is described. All the elements were co-designed in order to maximize the transmission dis ...

Synthesis of uniform amplitude focused beam arrays

Juan Ramon Mosig, Anja Skrivervik, Benjamin Fuchs

An iterative procedure for the synthesis of uniform amplitude focused beam arrays is presented. Specifically, the goal is to optimize the locations of a fixed number of array elements with known excitations in order to synthesize narrow-beam low-sidelobe p ...

Oblique incidence design of meander-line polarizers for dielectric lens antennas

Juan Ramon Mosig, Jean-François Zürcher, Marco Letizia, Benjamin Fuchs

A method to design planar multilayer meander-line polarizers is given. The proposed procedure is based on transmission line circuit theory and on full-wave unit cell analysis in frequency domain. The hybrid combination of those two techniques paves the way ...

Printed transition for SIW horn antennas - Analytical model

Juan Ramon Mosig, Marc Esquius Morote, Benjamin Fuchs

A printed transition is proposed to overcome problems limiting the performances of SIW horn antennas when built in thin substrates (thickness <λ 0/10). An analytical model to analyze its behavior is given along with design guidelines. The development of ...

2012

The joint synthesis of the spatial power pattern and polarization of arbitrary arrays is addressed. Specifically, the proposed approach gives the solution to a frequently encountered problem, namely the array design (i.e., the determination of the radiatin ...

UWB antenna design and ray tracing method for robot localization

Anja Skrivervik, Nuno Miguel Faria Pires, Marco Letizia, Benjamin Fuchs

This poster presents a new base station antenna design and preliminary results on electric field mapping for localizing a UWB-MICS robot in an arena. A batch of new base station antenna prototypes, was built and measured at EPFL - LEMA. A microstrip-fed co ...
