Reflective line source

Abstract

There is provided a reflective line source for an antenna system. The reflective line source comprises at least one region adapted to receive an electromagnetic field and to expand the field in at least one dimension. The reflective line source further comprises a reflective phase compensator that is coupled to the region. The reflective phase compensator is adapted to correct a phase error resulting from propagation of the field through the region as well as to fold a direction of propagation of the field. For this purpose, the reflective phase compensator comprises at least two reflective phase compensating surfaces oriented at ninety degrees relative to one another.
