Abstract :
The effects of stacking Koch fractal antenna aperture coupled fed are investigated. It is shown that by stacking the antennas the bandwidth can be increased up to 32% at the resonance frequency of 980 MHz which is much larger than the 3% bandwidth offered by a conventional Koch fractal antenna as well as having some 14% less surface area. This antenna has an 8dBi flat gain over the bandwidth. Simulated results on return loss, the E and H-plane patterns and gain are provided and discussed.
