Abstract

The radiation and propagation characteristic can be improved by the microstrip structure of the electromagnetic band-gap, which is becoming miniaturized today. In order to reduce the influence to the width of the band-gap brought by the miniaturization of the UC-EBG structure, a novel UC EBG structure is brought out. The band-gap width is guaranteed, meanwhile, the unit length is reduced to 0.1λ_g. Results of measurement indicate that this structure is effectively miniaturized, has an excellent performance, and can be used in the antenna or microwave circuit fields.
