A time-division duplex antenna apparatus according to an embodiment of the present invention includes: a transmitter which includes at least one transmission antenna module and transmits a downlink signal through a first path; a receiver which includes at least one reception antenna module and receives an uplink signal through a second path that is separated from the first path without any overlapping portions thereof; and a controller which controls the transmitter and the receiver in a time-division duplex manner."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time-division duplex antenna apparatus","description":"The present invention relates to a time-division duplex (TDD) antenna apparatus which can reduce signal loss, and thereby minimize the noise figure (NF) of a system and extend uplink coverage of the s","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11936417","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.
