Planar, multi-band, linear and circular polarized, electrically small, near field resonant parasitic antennas and their smart dust applications

We have developed a variety of electrically small, near-field resonant parasitic (NFRP) antennas. Their NFRP elements have been generally low profile but not conformal. Several examples and their performance characteristics will be presented. These will include both single- and dual-band, linearly (LP) and circularly polarized (CP) NFRP antennas. Several of these designs have been transitioned to electrically small planar versions to meet market inquiries. These planar NFRP antennas will be reviewed. The investigation of their use for electrically small sensors, such as smart dust, will be discussed. © 2011 IEEE
