The composite sheet includes: a magnetic sheet; and a conductor sheet stacked on the magnetic sheet for shielding an electromagnetic wave and radiating heat. The magnetic sheet includes: an amorphous ribbon sheet which is thermally treated, flaked, and then separated into a plurality of fine pieces; a protective film bonded to one side surface of the amorphous ribbon sheet; and an adhesive tape bonded to the other side surface of the amorphous ribbon sheet."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Composite sheet for shielding magnetic field and electromagnetic wave, and antenna module comprising same","description":"Provided are a composite sheet for shielding a magnetic field and an electromagnetic wave, and an antenna module using the same, which can block influence of a magnetic field on a main body and a batt","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9812774","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.
