Abstract :
The radiation fields of small air-cored toroidal antennas carrying a uniform in-phase current have been evaluated. It is shown that according to whether the number of turns is one or more, different radiation patterns result. For the single turn toroid the position of its null axis can be adjusted by altering the ratio of its mean radius to the radius of its cross-section.
