Abstract
Induction loop antennas are often inefficient due to skin and proximity effects, self-capacitance and tuning losses. However, an electric field antenna will generate a magnetic field which, in some circumstances, can exceed the field strength available from a loop antenna of similar mass and power dissipation.

Induction loop antennas are often inefficient due to skin and proximity effects, self-capacitance and tuning losses. However, an electric field antenna will generate a magnetic field which, in some circumstances, can exceed the field strength available from a loop antenna of similar mass and power dissipation. The main difficulty is in achieving efficiency at a small size. David Gibson explains how this may be achieved using high-permittivity ceramic tiles.
