TICRA are working with the Technical University of Denmark (DTU) on an ESA-ESTEC contract to develop an efficient and accurate modeling tool for printed reflectarrays.
With the enhanced analysis tool and TICRA’s expertise in reflector and horn optimization, efficient synthesis strategies for advanced printed reflectarrays are developed.
The results of this ESA-ESTEC study will be fully incorporated into TICRA’s software packages, which greatly enhance the possible modeling scenarios. Typical examples include combinations of solid reflectors and reflectarrays, design and optimization of contoured beam reflectarrays, high-level feed models or import of a measured feed field, as well as accurate evaluation of undesired effects such as strut scattering etc.
Sources of error in reflectarray analysis and how to overcome these issues to improve the analysis accuracy have been investigated. To this end, several benchmark reflectarrays that exaggerate some of the sources of error were designed, manufactured and measured at the DTU-ESA Spherical Near-Field Antenna Test Facility.
