Circular Polarisation Dual-Optics Proof-of-Concept
2014-01-01 -> 2015-06-30
Abstract: |
It is very expensive to launch satellites into space, which makes it important to use all resources as efficiently as possible. For a satellite communication system, the reflector occupies a large aperture. By designing a functional surface to reflect one polarisation and transmit the other, two reflectors can be implemented in the same aperture using complementary polarisations. This is easily implemented for linear polarisation using linear strip grids. However, there is an increased interest of using circular polarisation for new systems at Ka-band, which requires the implementation of a circular polarisation selective structure (CPSS).
This project is a proof-of-concept study for antenna systems using CPSS, where our task is to develop the electromagnetic design of the CPSS itself. It is a collaborative project funded by the European Space Agency (ESA), comprising Lund University, Technical University of Eindhoven, TNO, TICRA, and ASC. We are targeting a design with significantly increased bandwidth and maximum angle of incidence. The CPSS will be tested as a flat panel as well as a curved structure. |
