Strip-Type AMC Structure and Analysis to Its Band-Gap Characteristic

In this paper, the patch size effect of mushroom-like Sievenpiper AMC (Artificial Magnetic Conductor) structure to reflection phase band-gap is studied. It is observed that the reflection phase band-gap is independent of the size in the direction perpendicular to polarization direction of incident plane wave. Consequently, striptype AMC structure is introduced, and it is noticed this structure has independent reflection phase property and surface wave band-gap property. Compared with mushroom-like Sievenpiper structure, strip-type AMC structure is easier to design and fabrication, and has many advantages in antenna applications to circular patch antenna, plane spiral antenna and corrugated horn antenna etc.
