An efficient, low profile, electrically small, three-dimensional, very high frequency magnetic EZ antenna
Christopher L. Holloway
A very high frequency (VHF) version of the electrically small, coax-fed, three-dimensional (3D) magnetic EZ antenna was designed and tested. The fabricated antenna was formed by integrating a capacitively-loaded loop (CLL) element with a coaxially-fed, electrically small, semi-circular loop antenna. This low profile antenna (height ~ /25) had an electrical size that was ka ~ 0.46 at 105.2 MHz. Nearly complete matching to the 50 Ω source and a high overall efficiency (nearly 95 %) were achieved. The numerically predicted and the measured results were in good agreement.
