摘要：
Electromagnetic bandgap structures are well known for their stopband features and can be applied at microwave frequencies. In this work, a wide stopband electromagnetic band-gap (EBG) structure design based on 2D tapered slot array is presented. Each tapered slot length is designed to provide stopband at a specific frequency to maximize the attenuation level. The tapered slot array is positioned in the ground plane of a microstrip transmission line structure. Thus, the overall 9-slot nonlinearly tapered array produces a wide stopband from 9.3 to 20 GHz with attenuation better than 25 dB, which is observed in both simulation and actual measurements. The nonlinearly tapered EBG structure can be applied as an efficient lowpass filter. (c) 2006 Wiley Periodicals, Inc.
