Compact printed trapezoidal Koch fractal wide-slot antenna

摘要

A compact printed trapezoidal fractal shaped wide slot antenna with a microstrip line feed is presented. The proposed fractal wide slot, creates a miniaturized configuration for the specified frequency of operation. The electrical length of the antenna is increased due to the fractal configuration, without increasing the foot print of the antenna. The impedance matching is achieved by adjusting the position and length of the microstrip line feed under the slot. The proposed 3rd order printed trapezoidal fractal shaped wide slot antenna is operating at 1.9GHz and the reference printed square wide slot antenna operates at 3GHz for the same dimensions thus a size reduction of 61 % is achieved. Design and simulation results are presented and the antenna exhibits well defined radiation performance throughout the bandwidth of operation.
