Abstract

In this paper, electromagnetic bandgap structures are applied to a conventional coplanar waveguide. The EBG is obtained by etching a continuous sinusoidal perturbation pattern either on the central conductor strip or the both ground planes of the CPW. By doing so, a rejected frequency band appears. Since the frequency response of the device can be approximated by the Fourier Transform of the perturbation function, the application of a sinusoidal perturbation gives allows in principle a unique rejected band, without the presence of frequency harmonics. Full wave simulation results are presented for simple reflectors as well as for combination of several simultaneous perturbation functions, tailoring the desired frequency selective behavior.
