Controlling the Radiation Pattern of Fractal Array Antenna

Abstract

The fractal is researched and used in various fields now. However, very few studies have been reported on the using the fractal to design the array antenna. In addition, the method of controlling the radiation pattern of fractal array antenna has not been established. In this paper, we propose the method of controlling the radiation pattern of fractal array antenna. The fractal array antenna is made by using the fractal figure for the element position decision. In this work we applied the cantorl set to the controlling of fractal array antenna. The radiation pattern can be obtained by controlling the amplitudes only, it can be designed by using the digitally controlled attenuators. Then the effects of quantisation error on the radiation pattern are verified.
