Abstract

Higher order fractal patch antenna for multiband operation is discussed in this paper. Fractal structure is introduced to obtain the multiple frequency operation and to preserve the patch antenna properties like small size and low profile. The fractal patch antenna based on the basic structure, square is considered and the three iterations of the basic structure are simulated. The number of resonant frequencies will increase with the iteration order of the fractal antenna structure. The minimum number of resonant frequencies needed at each iteration is one more than the iteration order. The multiband behaviours of the proposed fractal antenna are proved by the results of simulations. The results are found useful in wireless applications also.
