Abstract

This paper presents an innovative design of a hybrid electromagnetic bandgap (EBG) structure based on nonuniform period and dimensions. A high rejection bandwidth is achieved when the nonuniform period and the dimensions follow the Kaiser distribution. The EBG structures are fabricated on the transmission line and the ground plane, where the offset is one‐quarter of the EBG period. The measurement results show a low‐pass filter response up to the C‐band with insertion loss below 0.25 dB and rejection bandwidth above 12 GHz. This type of nonuniform EBG structure is more compact than the conventional uniform structure. © 2005 Wiley Periodicals, Inc.

## Abstract A new design of electromagnetic band gap (EBG) waveguide low‐pass filter (LPF) loaded with double‐array is described to improve the stopband characteristics. Broader gapband width, about 2‐GHz broader than the traditional filters, greater stopband attenuation, and moderate passband inse
