Abstract :
In this paper a novel compact artificial magnetic conductor based on multiple non-grounded vias (MNGV) is introduced. This structure has more bandwidth in comparison with other compact structures neither use magnetic materials nor NICs presented recently and exhibits an acceptable stability of resonance frequency for the complete angular spectrum of incident plane waves. The unit cell size is decreased 81.6% by MNGV-AMC with single grounded via compared with the similar Sievenpiper AMC structure. Therefore antennas and microwave integrated circuits performance can be improved by increasing the number of cells in a finite space, especially in mobile communications.
