Design of a Miniaturized Dual Band Koch Fractal Boundary Microstrip Antenna

This paper presented a miniaturized dual band Koch fractal boundary microstrip antenna. Compared to the former prototype, the proposed antenna hold smaller size and better S 11 parameter at high frequency band. The prototype and proposed antennas were all simulated by HFSS. The results show that the height of the proposed antenna is about 20% less than the prototype antenna and the S 11 parameter at high frequency band was improved considerably.
