VARIABLE-CAPACITANCE ANTENNA FOR CONNECTION Russian patent published in 2005 - IPC

Abstract RU 2258282 C2

FIELD: antenna engineering.

SUBSTANCE: proposed antenna connected to electromagnetic-wave transceiving device incorporating one or more integrated capacitors has at least one insulating substrate-stenciled turn and substrate-stenciled capacitor connected in parallel for reducing capacitance afforded by capacitor(s) built in device. Resultant capacitance and turn form resonance-tuned circuit. Description of invention also includes method for antenna manufacture and its use in contactless or hybrid contact/contactless intelligent card.

EFFECT: reduced cost and labor input for antenna manufacture.
