The perforations comprise at least two longitudinal slots extending along and facing a portion of the antenna coil, each slot also opening onto the edge of the plate via a passage arranged on the edge. The invention also relates to a corresponding card produced by the method."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for producing a metal radio-frequency chip card with improved electromagnetic permittivity","description":"A method for producing a metal insert for a radio-frequency chip card includes the steps of forming or providing an assembly comprising an insulating substrate bearing: at least one antenna coil resti","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11501127","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.
