A Robust Multi-Band Sierpinski Gasket Monopole for Microwave Breast Cancer Imaging

Thanks to the intrinsic self-similarity, fractal antennas are characterized by multiple resonances, a feature that could be exploited in microwave imaging (MWI) for breast cancer to gather more information about the nature and position of the tumor. A Sierpinski gasket monopole antenna is presented in this paper, showing three operating bandwidths as well as high robustness to the presence of a numerical mammary phantom.
