Abstract
Disclosed is an antenna and a method of transmitting and receiving broadband circularly polarized signals. The antenna includes a substrate that has a first surface and an opposing second surface, and a first conductive element that is positioned at the first surface of the substrate. The first conductive element defines an aperture therein the first surface of the substrate. The antenna also includes a conductive strip positioned at the opposing second surface of the substrate. The conductive strip is electrically isolated from the aperture by the substrate therebetween, and, provides a transmission line that generates electromagnetic coupling with the aperture. Further, the antenna has a symmetric conductive element in the form of a planar polygon that is positioned relative to the aperture for broadband coupling of electromagnetic radiation. Furthermore, the opposing corners that are formed on the symmetric conductive element are configured to induce phase quadrature.
