FIELD: electrical engineering.
SUBSTANCE: antenna for contact-free interface of the in-built smart card with doubled interface includes card module (21) and microchip plate (22). Antenna itself includes base plate (12), folded antenna (11) fixed on the first surface of the base plate (12) and antenna lead terminal 1 and 2 (14, 18). The antenna is specific by the base plate (12) including structure (201) to interact with card module. The module also consists of the contact points 1 and 2 (C4b, C8b) locating on the second surface, open-end holes 1 and 2 (204, 208). In addition, contact point 1 and 2 (C4b, C8b) and structure (201) interacting with card module are located on the base plate in a position corresponding to the contact points of the in-built smart-card. The antenna lead terminals 1 and 2 (14, 18) are coupled with contact point 1 and 2 (C4b, C8b) through the first and second open-end holes (204, 208).
EFFECT: smart card antenna type may reduce cost of new services based on contact-free application.
