INDUCTANCE-CAPACITANCE ANTENNA Russian patent published in 2010 - IPC H01Q9/00 

FIELD: physics; radio.

SUBSTANCE: invention relates to antenna engineering and can be used in making small SW and USW band antennae. According to the invention, the inductance-capacitance antenna has an element connected to the braid of the feeder line and an element connected to the main conductor of the feeder line. The element connected to the braid of the feeder line has a current-conducting surface which carries out functions of a capacitor coating lying opposite the element connected to the main conductor of the feeder line, made in form of a flat inductance coil whose turns lie in the same plane from the centre to the perimetre of the coil with increase in the radius of the turns. The element with current-conducting surface and the element in form of a flat inductance coil lie parallel each other on the insulating element of the inductance-capacitance antenna. In order to tune to the resonance frequency, the element with current conducting surface can move to reduce or increase distance from the flat inductance coil, and the flat inductance coil can move to reduce or increase distance from the element with current conducting surface.

EFFECT: smaller antenna.
