Abstract (en)
An antenna for transmitting or receiving electormagnetic radiation, comprising a conductor configured to establish a closed standing wave path, and to inhibit the velocity of propagation and support a standing electromagnetic wave. An embodiment of the antenna shows a toroidal helix antenna [61], which is adapted for unbalanced feed from transmission line [62]. A sliding tap [65] is moved to a point for proper impedance matching.
