This enables controlling of an actual amplitude ratio r and a phase difference θ between currents I1 and I2 flowing through the two antennas 1 and 2 into desired values. Flows of the currents I1 and I2 with the phase difference θ through the antennas 1 and 2 enable forming of a favorable communication area. In addition, setting of the actual amplitude ratio r between the currents I1 and I2 flowing through the antennas 1 and 2 to a value other than 1 enables forming of an asymmetric communication area."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Antenna circuit","description":"In an antenna circuit including an antenna 1 and an antenna 2 that is connected in series with the antenna 1 and includes inductance, a variable capacitor Cv and a variable resistor Rv connected in pa","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10498037","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.
