Abstract
In this paper the use of Electromagnetic Band Gap (EBG) superstrate array configurations for Space applications are presented. Two space applications are covered, the first one is the Wide Area Augmentation System (WAAS) and the second one the C-Band geostationary TT&C telecommunication system. Both designs use as feeding configuration a 2×2 sequentially rotated patch array. In the first case, the EBG superstrate was formed by a square pattern of circular holes in a metallic sheet. In the second one, a metallic sheet with holes and equally distanced ring and jerusalem cross shaped metallic elements composes the EBG superstrate. The proposed EBG technology designs introduce simplifications to conventional antennas, as cost reduction, Beam Forming Network simplification, height reduction and low mass while offering similar RF performances.
