Study And Design Of A New Microstrip Fractal Antenna

Along with the popularization of modern communicate equipments, the application of antennas is becoming more and more extensive. In the area of wireless communication, Euclidean figures which take up finite room are adopted almost in all antennas. Along with the development of communication equipments, the requirements of multi-frequency and broadband characteristic antennas are increasing. Thus, many special shape antennas appeared. One of them will be introduced in this paper.The concept of Fractal was brought forward by French mathematician B.Mandelbrot in 1975. The Fractal means the characteristic of the part that is departed from a series of object with infinite nested geometry and enlarged is the same as that of the whole object. Fractal Technology is used in many area, but it was applied into the antenna design only 10 years ago. Fractal geometry is a muster that is independent on scale. It is self-similar which means its figures are similar under different scale. In the design of antenna to adopt Fractal technology, the figure of antennas is still similar when frequencies are different. Thus, the antenna achieves similar electric characteristics and an antenna with several frequency bands is obtained. Therefore, the study on the relationship of Fractal technology and antenna is inevitable. Applying the proportion self-similar characteristic and roomage filling...
