ELECTROMAGNETIC ANTENNA ( VARIANTS ) AND METHOD OF TRANSMISSION OF ELECTROMAGNETIC SIGNAL Russian patent published in 2003 - IPC

FIELD: radio engineering. SUBSTANCE: invention is related to helical antennas with opposite winding. Salient feature of invention consists in that helical antenna with opposite winding provides for uniform directional circulation of magnetic flux with the aid of collection of dipole elements. In correspondence with first variant of antenna design dipole elements have similar curving and each magnetic flux across corresponding dipole elements is guided in same direction relative to central signal coupler of loop antenna. According to second variant of antenna design dipole elements have opposite curving and magnetic fluxes across corresponding dipole elements are guided in opposite directions relative to central signal coupler of loop antenna. EFFECT: improved design of electromagnetic antenna that forms circulation of magnetic flux. 19 cl, 57 dwg
