A variety of multi-frequency, linear (LP) and circularly (CP) polarized, metamaterialinspired,<br />
near-field resonant parasitic (NFRP) antennas have been developed and<br />
tested successfully [1]-[6]. While they are in general low-profile, electrically small<br />
antennas, the demand for conformal versions has led to the development of planar<br />
versions. Several planar designs, inclu<strong>di</strong>ng not only high efficiency, single and multifrequency,<br />
LP and CP examples, but also higher <strong>di</strong>rectivity electrically small antennas<br />
and their experimental validations will be described.<br />
