Abstract :
The resonant frequencies of traditional Koch island fractal patch antennas and their narrow-slot counterparts are investigated. The simulation shows that at the stage of higher than the first iteration, the narrow-slot fractal patch antenna has a better effect in decreasing the resonant frequency and reducing the antenna dimension, and this is partly due to its higher performance in increasing the effective electrical length. By applying this new method, the antenna dimension can be reduced by 62% but still has a proper radiation pattern.
