Abstract

Cognitive systems call for wireless communications with antennas having stringent requirements. For example, software-defined radio, cognitive radio, and cognitive sensor networks operate over very wide bandwidth, with small dimensions, high gain, and omnidirectionally. A candidate capable of addressing such requirements is the fractal antenna. This paper describes selected simulations results of the following two fractal antenna: Koch and Minkowski. The variation trends of the voltage standing-wave ratio, the reflection coefficient, and the S11 parameters of the antenna have been studied for several successive iterates of the fractal shapes.
