Abstract :
In this paper several kinds of high impedance surfaces (HISs) such as mushroom, Jerusalem cross-shaped HIS, spiral-shaped HIS and meander line-based HIS are analyzed. The sensitivity of reflection phases with respect to incident angles for TE and TM-polarized wave are compared. A meander line-based HIS has the least sensitivity to variation of the incident angles and operates at lower resonant frequency. The simulations show that the designed meander line based-HIS has a bandgap region between 4.83 to 6.82 GHz for TE and TM surface waves.
