Abstract: A new compact fractal patch antenna is designed based on the fractal geometry. Based on the simulation results, the proposed antenna has shown an excellent size reduction possibility with good radiation performance for wireless communication applications. The change in resonating frequency with respect to the dielectric constant of substrate has shown and discussed in this paper. The various resonating frequencies for designed antenna are 8.59GHz, 9.2 GHz and 11.36 GHz for RT Duroid Rogers 6010, FR 4 and RT Duroid Rogers 5880 respectively. The S-parameter (S11) for resonating frequencies is well below -10 dB. The far-field patternandS11oftheproposedantennaissimulatedandanalyzedusingCST Microwave Studio 2011
