Abstract: Based on rectangle FSS structure, a novel element of FSS is designed using 3/2 dimensional fractal elements. Bysimulation using CST and comparison with Y fractal elements the character of the new element is analyzed. The result shows that thenovel FSS structure has multi-band frequency, and has well transmission character, angle independency and polarizationindependency, which proves that the novel FSS structure could be used in multi-band antenna.
