Abstract

A very high frequency version of the electrically small, coax-fed, three-dimensional magnetic EZ antenna was designed and tested. The fabricated antenna was formed by integrating a capacitively loaded loop element with a coaxially-fed, electrically small, semicircular loop antenna. This low profile antenna (height ∼λ/25) had an electrical size that was ka∼0.46 at 105.2 MHz (where a is the radius of the minimum enclosing hemisphere). Nearly complete matching to the 50 source and a high overall efficiency (nearly 95%) were achieved. The numerically predicted and the measured results were in good agreement.
