When the power receiving antenna enters the zone in which the power transmitting antenna is located, power is transmitted to the vehicle. By setting the width of the power receiving antenna as measured in the vehicle's width direction to be larger than the length of the power receiving antenna as measured in the vehicle's traveling direction, the transmission characteristic can be stabilized."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electric power supply system for vehicle including a power receiving antenna","description":"To stabilize the transmission characteristic of an electric power supply system for vehicle even when the vehicle being charged and powered by it shifts horizontally, a power transmitting antenna, whi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8536831","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.
