A novel bilateral UC-EBG structure

In this paper a new structure for uniplanar compact electromagnetic bandgap (UC-EBG) is presented that prohibits surface waves in bilateral manner. Firstly, the design of a unitcell is introduced and smaller cell size (0.35λ5.8GHz) is proven. Secondly, the unit-cell is extended in a periodic arrangement (7×5 cells), and functionality is proven through simulation and measurements of scattering parameters of a microstrip transmission line grounded with the periodic arrangement. A stop band with attenuation lower than -10 dB is achieved. Field profiles of frequencies inside and outside the stop band assured visually the claimed functionality proven by scattering parameters.
