Abstract
Fractal antennas have been demonstrated to enhance antenna properties due to their self-similarity behavior. We introduce a new self-similar fractal antenna based on nearly square shape with a circular polarization. This new antenna which is called the crown square fractal antenna displays lower first mode frequency than a normal nearly square microstrip patch antenna which results in reduced antenna size. This antenna shows four adjacent resonances that produce a pair of circularly polarized bands in a large VSWR bandwidth at high frequency modes. Radiation patterns of these two circularly polarized bands are similar.
