A novel circularly polarized fractal microstrip antenna

In this paper, we propose a novel fractal-shaped microstrip antenna. A square generator is used to construct this fractal configuration. Based on iterative processes, multiband spectrum performance is achieved. On the other hand, in the present fractal antenna, an L-probe, known as a broadband electromagnetic coupling probe, is used for feeding. Hence, matching between the feed system and the radiating system in a wide frequency range is easy. Also, the perturbation is set at an appropriate location in the patch element to excite circular polarization radiation.
