The second inductor comprises an electrically conductive track which at least partially surrounds a grounded electrically conductive core.The invention thus provides the transmitter and receiver for a communication system using near fields, and in which the input/output of the radio frequency circuitry can be balanced. The first coil produces the main magnetic induction field and the second coil is activated as an antenna producing an electric induction field. By this method, the operating range is increased and the relative positioning between both communication ends is less sensitive."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio receiver and transmitter circuits and methods","description":"A transmitter/receiver circuit comprises a wireless transmission/reception circuit having a first inductor for generating/detecting a magnetic induction field onto which an output of a radio frequency","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8532568","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.
