摘要

Fractal geometries have been applied to antenna design to make multiband and broadband antennas. In addition, fractal geometries have been used to miniaturize the size of antennas. However, miniaturization has been mostly limited to the wire (dipole and loop) antennas. In this paper, microstrip patch antennas are miniaturized using a modified Sierpinski carpet fractal geometry and are compared with the conventional rectangular patch antenna. Second and third iteration Sierpinski carpet apertures are made on a square patch. The Sierpinski geometry is modified by leaving a thin strip-shape conductor at the middle of the center aperture. This modification allows the probe position to be shifted to obtain 50 ohms. As a result, a 2.184 GHz square Sierpinski patch is about 17.43 % smaller than the conventional 2.184 GHz square patch with the same material. In addition, in this design, which uses probe feeding, the overall antenna volume is smaller than other microstripline-fed fractal antennas, found in the market. Finally, measurement results are compared to FDTD simulation results.
