A Dual Band Circularly Polarized Ring Antenna Based on Composite Right and Left Handed Metamaterials
By
, Vol. 78, 73-81, 2008
Abstract
In this paper a dual band circularly polarized antenna is designed, fabricated, and measured. Based on the concept of composite right and left handed (CRLH) metamaterials, the same phase constants and current distributions on the ring antenna are achieved at two frequency bands. Thus, the antenna has similar radiation patterns at both bands. The circular polarization is implemented by feeding two vertical ports from power dividers that provide equal magnitudes and quadrature phase excitations.
