The second RF antenna includes a first antenna part extending facing the metal layer to collect an image current induced by first eddy currents flowing in the metal layer, and a second antenna part electrically connected to the first antenna part and extending facing the recess area to allow a magnetic coupling between the first RF antenna and the second RF antenna."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Smart card with radio frequency antennas","description":"A smart card including a card body having a metal layer including a recess area which opens onto a peripheral edge of the metal layer, an RF chip, a first RF antenna connected to the RF chip and dispo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11984657","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
