This paper presents in detailed manner the progressive design and development of an active reflectarray using an active High Impedance Surface (HIS) as main reflector. Measurements demonstrating the performances and the radiation pattern agility of the proposed antenna concept are also presented and discussed.
This paper presents the first results in the development of a dual frequency Fresnel reflector which could be used as ground terminal for wideband telecommunication satellite systems operating at Ka-band.
In this paper, the latest improvements concerning the manufacturing and testing of a prototype concluding the development of a waveguide fed active antenna using an active High Impedance Surface (HIS) as main reflector are reported. The capability of such an antenna to generate various types of radiation beam (focalised, scanned...) has been demonstrate.
This paper presents a new technique to measure the reflection phase coefficient of High Impedance Surface structures. The proposed technique, which is simple to implement and requires little measurement time, has been validated with measurements performed on an active HIS used in the design of a reconfigurable active reflector antenna.
In this paper, the manufacturing and testing of a prototype concluding the development of a waveguide fed active antenna using an active High Impedance Surface (HIS) as main reflector are reported. The capability of such an antenna to generate various types of radiation beam (focalised, scanned…) has been demonstrated.
In this paper, the latest developments concerning the design of the unit cell of one adjustable high impedance surface (HIS) using varactor diodes are presented. The HIS obtained with this new unit cell is used in the design of a centred reflectarray antenna able to generate various types of radiation pattern beam (focalised, scanned, shaped...).
