Abstract
An antenna has windings that are contrawound in segments on a toroid form and that have opposed currents on selected segments. The windings may have a helical pattern, poloidal peripheral pattern or may be constructed from a slotted conductor on the toroid. Poloidal loop winds have a toroid hub on a toroid that has two plates that provides a capacitive feed to the loops, which are selectively connected to one of the plates.
