ULTRA-WIDEBAND SMALL-SIZE ANTENNA AND COMMUNICATION DEVICE HAVING SAID ANTENNA Russian patent published in 2014 - IPC H01Q1/24 

FIELD: radio engineering, communication.

SUBSTANCE: ultra-wideband small-size antenna has: an earthing element placed in the immediate vicinity of the surface of the human body; a radiating element whose external dimensions are close to those of the earthing element lies away from the earthing element in a direction approximately perpendicular to the surface of the body at distance of 0.2-0.5 times the average wavelength of the working frequency range; a short-circuiting element mounted in at least two copies and configured to connect the earthing element to the radiating element at such points that its position is approximately perpendicular to the surface of the body; a conducting power element connected to the earthing element and the radiating element at arbitrary points, arranged in a position which is close to being perpendicular to the surface of the body, and has a gap in an arbitrary region with size of not more than 0.125 times the smallest wavelength of the working range, wherein said earthing element and radiating element are oriented in parallel to the surface of the human body, and the earthing element and/or radiating element has at least three slit cuts with an arbitrary shape. The communication device is designed to use such an antenna.

EFFECT: providing a high transfer constant in a radio link between terminals on the surface of a human body.
