Multiband EBG navigation antenna
EBG superstrate based antenna designs can find its applications in Geosynchonous Satellite Navigation (GSN) System Antennas, since they allow to reduce the number of radiating elements while keeping the required high directivity and circular polarization. Their use will considerably simplify the feeding network and simultaneously reduce the antenna mass and volume. A dual layer EBG superstrate which can be easily tuned to the desired frequencies is presented in this paper. The design has been optimized to comply with the navigation antenna requirements of Wide Area Augmentation System (WAAS) application in L1 and L2 bands.
