Abstract

Fractal geometry has been used in the design of antenna elements to achieve miniaturization, to lower the Q of the antennas and to attain multiple resonances. These benefits and design techniques have been applied to the design of scanned phased arrays and frequency selective surfaces. These designs have been simulated using the moment method and the finite difference time domain (FDTD) techniques as well as fabricated and measured.
