In this paper, a new compact, low profile multiband patch microstrip antenna
design is presented as a candidate for use in modern multi-functions communication
systems. The proposed antenna design is fractally generated using Koch fractal curve
geometry applied to the conventional square microstrip patch antenna. Antenna
structures resulting from the successive iterations in the proposed fractal generation
process show a considerable size reduction compared with the conventional microstrip
patch antenna designed at the same frequency using the same substrate material
specifications. Simulation and theoretical performance of the resulting antenna
structures corresponding to the different fractal iteration levels have been carried out
using method of moments (MoM) based software package IE3D, which is widely used
in the fields of microwave research and industry. Simulation results have proved the
multi-resonant behavior of the presented antenna structures besides the considerable
size reduction gained. The results also show that these antenna structures possess
adequate radiation performance.
