Abstract: It is very demanding from commercial and military applications to have small size low profile multiband antenna. This proposed work gives a path to transform a dual band antenna into multiband antenna. The geometry of the antenna is defined by designing some circular crown fractal-like erosion in a conventional rectangular patch structure and found the best suited positions for slots which can give multiband operations. Fortunately finally selected position gives enhanced bandwidth and satisfactory return and other characteristics also. In this work we first proposed small size antenna which works on single resonance frequency then it is modified to get multiple resonance frequency operations. For newly designed multi band slot cutted shape antenna gives satisfactory results. Then the results are also processed by the ANN (Artificial Neural Network). Resonance frequency is simulated by IE3D simulator and then simulated results are used o train the neural network, both the results found are almost close to each, very less mean squared error occurs. It gives Return loss for all resonant frequencies less than -10db, VSWR less than 2 with multiband resonance frequencies. Applications of this multiband antenna are in the X, Ku and K band of Super High Frequency range.
