This project aims at the development and realization of a new technology for compact directive antenna with an automatic beam tracking over a large angular sector without any performance degradation. The Multilayered Luneberg Lens based on association of several layers of different density foams combined with a conformable RF source movable along the outer surface offers very good performances in term of gain and beam scanning. Both lens and RF source can be realized with foam with a specific metallization for source radiation and via holes for feeding or to add reactive loadings. As a matter of fact many antennas to day need some conformability and exhibit also multilayered structure either to increase bandwidth, multifrequency property or to focus EM energy. This means development of new materials such as conformable foams with controlled electric permeabilties, and development of new mecatronics devices including light and strong mechanical foam structures and the electronic control of tracking.
Short description of the task performed by Croatian partner
The main task is to develop a code which permits the rigorous calculation of radio performances of the whole half-spherical Luneberg lens + source such as patch conformed type or horn. The protective radome should be included in the calculation.
