multiband calculation

wat would be the best way to calculate the 1st, second and nth band of an antenna eg. fractal square patch and microstrip square patch?


thanks

Hi,

I think you only need a basic understanding of the antenna structure (e.g. for rectangular patch you will have resonances when the length is multiples of half the effective wavelength) for fractal antennas you will have resonance at the corresponding frequency of each iteration and there multiples.
