Abstract
A circularly polarized antenna includes a finite, conducting base plate defining a base plane, and an S-shaped top part defining a top plane parallel to the base plane, wherein the top plane has a non-zero distance from the base plane, and wherein both ends of the S-shaped top part have an end contact coupled either to the base plate or to an antenna feed. The antenna is configured to be fed single-ended or differentially to produce at least one pair of co-aligned electric and magnetic dipoles.
