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 non-uniform 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.
