Diversity-Multiplexing Tradeoff for the MIMO Static Half-Duplex Relay

Olivier Lévêque

In this paper, we investigate the diversity-multiplexing tradeoff (DMT) of the multiple-antenna (MIMO) static half-duplex relay channel. A general expression is derived for the DMT upper bound, which can be achieved by a compress-and-forward protocol at th ...

Impact of substrate permittivity on the performance of UWB monopoles

Anja Skrivervik, Jean-François Zürcher, Gabriela Quintero Diaz De Leon

The effect of substrate permittivity on UWB antenna radiation is studied. Microstrip and CPW-fed UWB monopoles are designed using substrates with different dielectric constants. The radiation patterns are measured. The transfer function of a two identical ...

Antenna research restructuring in Europe: the Antenna Center of Excellence (ACE)

Juan Ramon Mosig

The EU Framework Programmes (FPs) foster the collaboration and the research structuring across Europe. In FP6, the Antenna Centre of Excellence (ACE) is a Network of Excellence project created to improve the efficiency of antenna research in Europe. Starti ...

Enhancement and subwavelength confinement of light in plasmonic nanostructures

Holger Fischer

This work includes the fabrication of plasmonic nanostructures as well as the investigation of their optical properties in the near-field and in the farfield. As expressed in the title of this thesis the focus lies in the subwavelength confinement and enha ...

Modeling challenges in computational electromagnetics

Ivica Stevanovic

Abstract Printed multilayered media with metallizations embedded between dielectric layers are one of the most successful technologies for manufacturing planar structures with a good performanceto-price ratio. These structures range from PC board circuits, ...

Acoustic goniometry

Eric Van Lancker

This work was motivated by the increasing need for acoustic localization systems. The various localization systems that were implemented during this PhD include localization of snow avalanches, artillery and supersonic aircraft in the infrasound domain, th ...

Codes for differential signaling with many antennas

Mohammad Amin Shokrollahi

We construct signal constellations for differential transmission with multiple basestation antennas. The signals are derived using the theory of fixed-point- free groups and are especially suitable for mobile cellular applications because they do not requi ...

Integrated SSFIP-horn antenna at 75 GHz

Juan Ramon Mosig, Philippe Renaud, Anja Skrivervik, Jean-François Zürcher

We present in this paper an integrated cavity-backed patch antenna operating at 75 GHz. The design was optimized using a full-wave software based on the integral-equation method. The antenna was realized using micromachining technologies on two wafers: a s ...
