Abstract
An antenna includes a first body having a ring monopole and a second body positioned below the first body. The second body can have a plurality of notched ring resonators. A spacer can be positioned between the first and second bodies. In some embodiments, the second body can define an artificial ground. In addition, the ring resonators can be arranged and configured to generate a 180° phase difference between polarized waves so that a radiated wave from the ring monopole and a reflected wave from the artificial ground have orthogonal polarizations and a 90° phase difference to form a circularly polarized radiated wave.
