Compact Artificial Magnetic Conductor Designs Using Planar Square Spiral Geometries
By
, Vol. 77, 43-54, 2007
Abstract
Compact spiral artificial magnetic conductors (AMC) have been investigatedin this paper. First, single andd ouble spirals are examinedto achieve an in-phase reflection at a lower frequency comparedto a conventional patch element of the same size. However, these two designs generate a large cross polarization. The cross polarization affects the operating frequency and bandwidth. In order to eliminate the cross polarization effect, a four-arm spiral element is introduced. This geometry does not generate a cross polarization, and an operating frequency that is 49.45% lower than the reference patch element has been achieved.
