A New Ultra Wideband Fractal Monopole Antenna摘要
Ultra wideband antennas are used greatly in commercial and military communication systems. A reduction in physical size and multiband capability are very important in the design of ultra wideband antennas. The use of fractal geometry in antenna design provides a good method for achieving the desired miniaturization and multi-band properties. In this paper, a compact, multi-band, and broad-band antenna based on new fractal geometry is designed, simulated, and measured. The proposed design is achieved by applying the 2nd iteration of a new fractal geometry to a wire monopole antenna. A numerical electromagnetics simulation is performed using SuperNEC electromagnetic simulator software. The results show that the proposed antenna can be used for 6 GHz – 30 GHz frequency range. Radiation patterns are also studied.
