The concept of a PBG cell is introduced in this letter, and a novel one‐dimension (1‐D) microstrip photonic bandgap (PBG) cell structure is proposed. It is a section of a microstrip with a special perforation pattern on the microstrip line itself. By controlling the pattern and size of the perforation and the length of the section, this cell exhibits different slow‐wave and bandstop characteristics at different frequencies. A series of these cells appears as a bandstop filter, while it still can be used as a slow‐wave transmission line outside the stopband. © 2000 John Wiley & Sons, Inc.
