A rigorous consideration of the filtering effect of EBG structures at the microwave‐frequency range will be performed in this paper. We will show that, in this frequency range, the periodic‐structure filtering (or Bragg effect) and the self‐resonance of the different cells involved are tuned approximately at the same frequencies; thus, their influences are mixed in the final filter response. Both effects are defined by different geometrical laws and this is probably the main reason not to use a standard design method for a given filter requirement when using these technologies. © 2004 Wiley Periodicals, Inc.
