The wireless revolution is creating a flood of new wireless devices that dramatically increase the availability of voice, video and data services nearly anywhere in the world. While this revolution is significantly expanding the opportunity for new, smaller and better wireless communication terminals, it also is creating new performance demands for antennas to fulfill the need to miniaturize communication devices. The antenna engineers dilemma "bandwidth and antenna size are inversely related". The bandwidth of a small antenna can be increased by decreasing the efficiency, thereby reducing the gain. As the antenna gain and size are directly related", the maximal gain of an antenna can be enhanced by varying the geometry and the bandwidth can be similarly increased. Wire antenna is a winning competitor in antenna design as it is simple, cheap, and easy to be acquired practically. In the proposed design a conical antenna over a metallic disc is introduced and their characteristics are enhanced using fractal designs.
