| Abstract: | This paper propose a method to design a ultra-wideband(UWB) Koch fractal slot antenna.By employing Koch fractal shape wide slot,the volume of the antenna may be decreased drastically.By adjusting the length of the Koch fractal's edge, flexible frequency notched function can be achieved.The designing procedure of the antenna is also presented.The antenna and its large-scaled prototypes are evaluated experimentally for their frequency notched function.The well-accordance between numerical and experimental res... |
