ANTENNA Russian patent published in 2008 - IPC H01Q1/36 

FIELD: designing small-size antennas for receiving and transmitting ultra-broadband signals of miscellaneous radio systems.

SUBSTANCE: proposed antenna has bifilar helix with opposing turns disposed in one plane, internal ends of turns functioning as antenna excitation points; and two antenna elements connected to external ends of turns and disposed in spiral plane; current radius of each turn of helix is determined by mathematical expression given in formula. Each antenna element is made in the form of comb structure with rounded-off tops of crests and rounded-off cavities between crests; tops of crests of one of antenna elements are opposing those of other antenna element and crest foots of each antenna element are integrated; helix turns are connected to respective feet of respective antenna-element crests.

EFFECT: enlarged functional capabilities, improved performance characteristics.
