Document Type and Number:
WIPO Patent Application WO/2020/246838
Kind Code:
A1
Abstract:
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 the uplink coverage of the system, by separating a transmitter circuit from a receiver circuit of the antenna apparatus, and disposing a low noise amplifier (LNA) of the receiver circuit between a reception antenna and a reception filter of the receiver. 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.
