The IC chip is connected between a first terminal disposed on a first end of the first antenna element and a second terminal disposed on a first end of the second antenna element. The loop antenna includes an overlapping part at a second surface side of the base part, and a capacitance of the overlapping part is adjusted such that a difference between an imaginary component of a first synthetic impedance and an imaginary component of a second synthetic impedance is less than or equal to a predetermined value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"RFID tag and RFID system","description":"An RFID tag includes a base part, a loop antenna around the base part including a first antenna element and a second antenna element, and a loop-length shorter than a wavelength of a resonant frequenc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9703997","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.
