Radiation Properties of Fractal Microstrip Antennas

The fundamental configuration method and radiation characteristics are described for a new type of multiband planar antenna in which triangular microstrip antennas (MSA) with a Sierpinski fractal structure are used as the radiating elements. In order to verify the performance of the present antenna system, Sierpinski triangular microstrip antennas with multiband characteristics are fabricated for trial in the C band and X band. According to the experiment, excellent multiband characteristics can be obtained with the proposed antennas. The measured radiation patterns agree very well with those obtained by numerical calculations. Hence, it is clear that the present antenna system can be a promising format for a multiband planar antenna with a low profile. © 2005 Wiley Periodicals, Inc.
