Surface wave bandgap of mushroom-like electromagnetic bandgap(EBG) structure with finite units was analyzed by direct transmission method. Compared with surface wave dispersion diagram, surface wave bandgap is fast determined and analysis time obviously shortened. The effect of different waveguide heights and periods of EBG structure on surface wave bandgap was analyzed by simulating the transmission coefficient of waveguide in which the EBG units were placed. The EBG structure dielectric board was fabricated and the surface wave bandgap was measured. Experimental results show that surface wave bandgap determined by this method is consistent with the measured one.
