Efficient dual-band planar array suitable to GALILEO
06 November 2006
An optimum dual band self-diplexed antenna, particularly suitable to accomplish the demanding requirements of the European Navigation System (GALILEO) is highlighted. The antenna relies on the key enabling technologies previously developed for the pioneering GIOVE-A satellite (Galileo In Orbit Validation Element) successfully flown on 28 December 2005. Its excellent operational status and the quality of transmitted signal are a validation of the technology solutions adopted to the antenna. Both GIOVE-A and the enhanced design will be described, in particular the solutions adopted to improve the overall performance Vs Galileo.
