In this paper, the Giusepe Peano fractal geometry is applied to the slot antenna, as a novel method for the miniaturization and realization of wideband impedancebandwidth with stable radiation patterns and without any gain and efficiency degradation. An example of Giusepe Peano fractalslot antenna for the second iteration at operating frequency of 4 GHz has achieved a bandwidth of 5.9 GHz. The result of computer simulations and measurements data of a fabricatedprototype model agree quite well and verify the proposed novel antenna structure. Furthermore, the antenna radiationperformance is investigated for various directions of feed line relative to the slot orientation. It is observed that the case of feed line along the diagonal of fractal square slot provides the bestradiation performance, namely the bandwidth increases to about 7 GHz.
