Abstract：Photonic BandGap (PBG) is man-made periodic dielectric structure, which may control the propagation of electromagnetic waves in certain frequency range. And the Uniplanar Compact Photonic BandGap (UC-PBG) is a periodic photonic bandgap on a conductor-backed dielectric substrate. This paper introduces a waveguide using the UC-PBG structure, which replace the two bilateral sides of a rectangular waveguide. The simulations with Ansoft HFSS indicate that the TE10 mode can be converted to quasi-TEM mode in the range of 15.15 GHz-15.60 GHz with the UC-PBG structure.
