Abstract: A novel broadband electromagnetic band-gap (EBG) structure is presented using cascaded mushroom-like structure with different radius of via. Direct transmission method is used to determine the band-gap of the EBG structure. The effects of the radius of via and unit number on the mushroom-like EBG structure are investigated. Two kinds of unit with different via radius are cascaded to enlarge the band-gap of EBG structure, which achieves almost 70%. The simulation and experimental results show that the band-gap covers the stop-band produced by the two uniform configurations with different radius, respectively. © 2008 Wiley Periodicals, Inc.
