Time division duplex antenna device

The present invention relates to a time division duplex (TDD) antenna device in which a transmitter circuit and a receiver circuit of the antenna device are separated, and a low noise amplifier (LNA) of the receiver circuit is disposed between a reception antenna and a reception filter of a receiver to reduce signal loss, whereby a noise factor (NF, NF, NF) of a system can be reduced, and the noise factor (NF, NF, NF) of the system can be reduced. According to the invention, the uplink coverage range of the system is minimized and the uplink coverage range of the system is expanded. The time division duplex antenna apparatus according to an embodiment of the present invention comprises: a transmitter comprising at least one transmitting antenna module for transmitting a downlink signal through a first path; a receiver including at least one reception antenna module and receiving an uplink signal through a second path separated from the first path so as not to overlap with the first path; and a controller that
