Because fractal antennas are small and versatile, they are ideal for creating more compact RFID equipment — both tags and readers. The compact size ultimately leads to lower cost equipment, without compromising power or read range. In this section, some fractal antennas will be described with their simulated and measured results. They are classified into two categories: 1) Fractal Dipole Antennas; which include Koch fractal curve, Sierpinski Gasket and a proposed fractal curve. 2) Fractal Loop Antennas; which include Koch Loop and some proposed fractal loops.
The challenge is to design small and efficient antennas that have a fractal shape. l (a) Initiator (b) Generator Fig. 4. Initiator and generator of the standard Koch fractal curve. Dipole antennas with arms consisting of Koch curves of different indentation angles and fractal iterations are investigated in this section. A standard Koch fractal dipole antenna using 3rd iteration curve with an indentation angle of 60° and with the feed located at the center of the geometry is shown in Fig. 5. Fig.
