Multi-functional, electrically small, metamaterial-inspired, near-field resonant parasitic antennas

Electrically small antennas continue to be a critical enabling technology for many wireless applications. The design, fabrication, and testing of a variety of metamaterial-inspired near-field resonant parasitic antenna systems have demonstrated that they can meet many of the performance demands for those applications, including high efficiency, broad bandwidth, and multi-functionality. Several of these multi-functional designs, their operating characteristics, and experimental confirmation of their predicted behaviors will be reviewed.
