Abstract Sinusoidal and triangular patterns etched in the ground plane of a microstrip line are proved to suppress the periodicity in the frequency response that arises in the recently proposed photonic bandgap microstrip structures with discrete periodic patterns. Experimental data show a reduction in the harmonic level of around 50 dB for the novel patterns proposed. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 25: 33–36, 2000.
