The simulation of the multi-band triangle fractal nesting printed monopole antenna

Based on the triangle fractal antenna, is proposed in this paper. This antenna consists of four nesting triangles with different vertex angle and height. The simulation of the antenna is performed by using CST MICROWAVE STUDIO® and the result shows that the center frequency of the pass band and the bandwidth can be controlled by modulating the height and angle of the nesting triangles and the nesting number. A multi-band with four bands (2.4GHz, 3.5GHz, 5.2GHz and 5.8GHz) has been designed, through simulation. The nesting fractal antenna is a multi-bands antenna with controllable frequency bands. And it also has a broad application prospects.
