Abstract
An antenna system may include a source antenna, a frequency selective surface (FSS), and a second antenna or a fluidic channel associated with a housing. In both examples, the FSS has a first side and a second side opposite from the first side. The first side includes horizontally oriented unit cells positioned as multiple columns of unit cells. The first side of the FSS faces the source antenna and is separated from the source antenna by a defined distance. The housing is positioned on the second side of the FSS. In the latter example, the fluidic channel of the housing includes one of air or deionized water. The fluidic channel is positioned on a portion of the second side of the FSS that is opposite to a subset of the horizontally oriented unit cells on the first side of the FSS.
