Dual-band CRLH-TL Based Patch Antenna with Pattern Diversity

This paper proposes a low-profile patch antenna with pattern diversity, by combining an annular ring together with a center-fed circular patch. The dual-band operation is realized by loading a type of planar metamaterial, i.e. a composite right/left-handed transmission line (CRLH-TL) on the patch. The outer ring and inner circular patch can provide broadside and omnidirectional radiation patterns, respectively. The measured correlation coefficient is lower than 0.04 and 0.05 in the lower and upper band, respectively.
