The manufacture and characterisation of an elastic dipole antenna that is reversibly deformable and stretchable is described. The metallisation technique of depositing sub-micron-thick gold (Au) film on pillar patterned elastomer polydimethylsiloxane has b ...
In this work a conceptual design of a conformal antenna array is presented for a millimeter-wave antenna system, optimized for low-cost mass production in PCB technology. The conformal array is constituted by four cube faces with two antennas realized on e ...
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 ...

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 ...
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 ...
This paper presents implementations of very wideband antennas with reconfigurable band-rejection filtering within the band. The base antenna topology used is a dipole slot bow-tie whose maximal dimension at the lowest matched frequency is only 0.2λ0. The a ...
The electric field enhancement associated with detailed structure within novel optical antenna nanostructures is modeled using the surface integral equation technique in the context of surface-enhanced Raman scattering (SERS). The antennae comprise random ...
For the universities of the emergent countries, and those of Cameroon in particular, the fight to reach a durable development requires to know the needed scientific and technical information for their development, how to get it and to spread it out among p ...
The main purpose of the System Fidelity Factor (SFF) is to incorporate frequency and time domain characteristics of an antenna system into a comparison method for ultrawideband (UWB) antennas. The SFF is an interesting tool because both simulations and mea ...

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 ...
