PBG‐type microstrip filters with one‐ and two‐sided patterns

We report first on an experimental analysis of photonic bandgap microstrip‐type filters at microwave frequencies. The frequency‐selective structure is achieved via ground‐plane patterning. The influence of a shielding is addressed in particular. Then, we theoretically analyze the possibility of two‐sided patterning for a high dynamic broadband filtering response. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 30: 69–72, 2001.
