Abstract

Several variations of a 300 MHz version of the electrically small coax-fed three-dimensional (3D) magnetic EZ antenna were designed and tested. The final design was achieved when the impact of the fabrication techniques on its parameters were understood completely. The final version of this low profile antenna had an electrical size that was ka=0.43. Nearly complete matching to the 50 source and high overall efficiency (nearly 100%) were achieved. The measured fractional bandwidth was approximately 1.4%. The numerically predicted and the measured results of this electrically small antenna were in good agreement. Comparisons of the same driven element connected to the source with an appropriate external matching network confirm the performance enhancement achieved with this metamaterial-inspired resonant near-field parasitic element.
