Abstract
Modern wireless communication systems need antennas with further bandwidth and smaller size. Fractals have unique properties such as self-similarity and space-filling. The concepts of fractals can be applied to the design of low-profile and multi-band antennas. In this article, a super wideband antenna by applying a new fractal geometry to a wire monopole antenna is presented. The modelling and simulation are performed using SuperNEC electromagnetic simulator. The results show that the proposed antenna can be used for frequency range 10–40 GHz, i.e. it is a super wideband antenna with 30 GHz bandwidth. Radiation patterns and gain are also studied and show a good agreement over the bandwidth.
