A combination of metastructures is used to achieve high directivity, electrically small, low-profile, linear (LP) and circularly polarized (CP) near-field resonant parasitic (NFRP) antennas. A conformal metamaterial-inspired Egyptian axe dipole antenna is introduced, and its performance characteristics are presented. The electrically small, low-profile LP and CP high-directivity systems are achieved by amalgamating this NFRP antenna with an electromagnetic band-gap (EBG) structure, which acts as an artificial magnetic conductor (AMC) ground plane. As with all of the nonconformal metamaterial-inspired antennas, the designs of the driven and parasitic elements of these low-profile antennas are tailored to achieve nearly complete matching of the entire system to a 50-$\Omega $ source without any matching network and to yield high radiation efficiencies.
