A Novel Semi-circle Fractal Multi-band Antenna
This paper proposes a novel multi-band semi-circle fractal antenna which develops from the multiple ring antenna. The antenna consists of nesting semi-circles with different radii. Simulated on the commercial software CST MICROWAVE STUDIO? the multi-band characteristic of the novel antenna can be controlled by modulating the radii of the nesting semi-circles and the nesting number. Summarized from the impact of these parameters, antenna with three passbands (900MHz, 1.8GHz, and 2.4GHz) has been designed. In order to remove the infinite conductive ground, the antenna patch is placed on FR4 board and fed to get the printed antenna. The simulation results indicate that the antennas also have three pass bands with the same central frequencies with wide bandwidths. The antenna is manufactured and measured, the experiment results fit well with simulation. Thus, the multi-band semi-circle fractal antenna is a novel antenna with controllable frequency bands and promising application.
