Resumen

In this paper, a design technique of high-performance low-pass filters based on electromagnetic bandgap structures(EBG) in microstrip and coplanar (CPW) technology is introduced. The proposed design technique consists of astepped impedance synthesis, using Chebyshev functions and circular patterns etched in the ground planes of themicrostrip and CPW lines. This approach improves the return loss and reduces the ripple in the passband of thetraditional EBG- and DGS-based wide stop-band filters. Two fifth-order low-pass filters have been designed,simulated and measured in microstrip and CPW technologies. Both filters were manufactured on a Roger 6010substrate. A good agreement between simulated and measured results was obtained for these designed filters.Moreover, high-performance in both passband and stopband, and compact size compared with other reported EBGand DGS- based low-pass filters were obtained.
