Modified Minkowski Fractal Yagi-Uda Antenna

Abstract

A fractal Yagi-Uda antenna operating in the 800–960 MHz frequency band is developed and examined in this work. Improvement of bandwidth is achieved through usage of modification of Minkowski fractal - combination of first and second order of the fractal. The SWR, gain, front-to-back ratio and radiation pattern are simulated and compared with these of classic Yagi-Uda antenna. Real model is also assembled and SWR was measured and compared with simulated one.
