Abstract
In some examples, an antenna system includes a source antenna and a frequency selective surface (FSS) comprising a first section including a first set of horizontally oriented unit cells, a second section including a second set of horizontally oriented unit cells, and a third section between the first section and the second section, the third section including a set of vertically oriented unit cells, wherein the first section is substantially square in shape, and wherein the second section is substantially square in shape. The source antenna is configured to emit one or more electromagnetic signals through the FSS, wherein the FSS causes the one or more signals to form at least a first beam corresponding to the first section, and wherein the FSS causes the one or more signals to form at least a second beam corresponding to the second section.
