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 ...
In this study, a dual frequency circularly polarized reconfigurable reflectarray (RA) cell with RF-MEMS switches is designed. RA combines the advantages of reflector-based and phased array antennas, providing a low-cost and high performance antenna array s ...

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, ...
In this paper we propose the dynamic control of the beamwidth of partially reflective surface (PRS) antennas. Theoretical aspects are presented together with modeling issues. The potential and limitation of the concept are then evaluated. Finally, a detail ...
The dynamic control of the beamwidth of a partially reflective surface (PRS) antenna is reported for the first time. First, a design methodology is proposed by revisiting the PRS antenna theory from the perspective of its reconfigurable beamwidth operation ...

Reflectarray antennas have attracted significant attention due to a number of attractive properties, such as low cost, and conformal deployment capability. In addition, the drive towards flexible radio transceivers, enabling beamforming and multi-beam oper ...
This work presents the design and realization procedure of small implantable antenna for biotelemetry applications. The radiator occupies a volume smaller than 3 cm(3) (without its biocompatible insulation), is well matched within the Medical Implanted Com ...
Novel acousto-optic processors for control and signal processing in phased-array antennas are presented. These processors can operate in both the antenna transmit and receive modes. An experimental acousto-optic processor is demonstrated in the laboratory. ...
We experimentally demonstrate a novel technique to process broadband microwave signals, using all-optically tunable true time delay in optical fibers. The configuration to achieve true time delay basically consists of two main stages: photonic RF phase shi ...
In this paper, a full-wave software tool for the accurate prediction of the RF breakdown in microstrip transmission lines is presented. The main objective of the project is to develop a software tool capable to predict the Multipactor and Corona breakdown ...
