A Review of Fractal Tree Antennas

 This work is supported by the director fund of State Key Laboratory of CEMEE (CEMEE2014Z0102B) and the National Natural Science Foundation of China (61001002) Abstract - Fractal tree structures can be utilized to design antennas in order to enhance the performance of the antenna, such as widening the working frequency band while reducing the size of the antenna. This paper summarizes the development process, current research, and the application of fractal tree antenna in miniaturization, multi-band and ultra-wide band antennas. And it also analyzes its development as well as application prospect. Index Terms - fractal antenna, fractal tree, multi-band, ultra- wide bandwidth, miniaturization
