Compact ACS-Fed Koch Fractal Shape Antenna for Wideband Application

A compact Asymmetric coplanar strip (ACS) fed modified Koch fractal shape printed slot antenna. It suitable for Wireless, WiMax, WiBro and other important frequencies, is presented in this paper. Here, the operating frequencies of the triangle slot antenna are lowered by the Koch iteration technique resulting in compact antenna. The proposed antenna exhibits wideband frequency resonance. The simulated -10 dB bandwidth for this resonant frequency is 97.7 % ranging from 2.7 GHz to 7.88 GHz. The antenna is exhibits omnidirectional radiation pattern with < 3 dBi gain for entire bandwidth is presented. Also comparison of different antenna parameters are presented and discussed in this paper.
