Fractal antennae are recent topic of research interest. This work reports a self- complementary Sierpinski Gasket fractal microstrip patch antenna. The flrst iteration is named CSMASLI1, which stands for Complementary Sierpinski Microstrip Antenna Same Layer Iter- ation 1 and similarly the second iteration is named as CSMASLI2. The antennas are analyzed for two iterations using commercially available electromagnetic simulation software IE3D TM and CST Microwave Studio TM . The antenna radiates prominently at all resonant frequencies. The impedance bandwidth increases at higher harmonics. The radiation pattern is consistent for the difierent resonant frequencies and for difierent iterations. However some undulations are ob- served at higher resonance. Thus this new design can have usage in vehicle-mounted antenna for multiband wireless systems. A prototype was experimented which matches simulated results.
