Claim 0:
1. A time-division duplex (TDD) antenna apparatus transmitting and receiving a downlink signal and an uplink signal, comprising:
a transmitter comprising at least one transmission antenna module and configured to transmit a downlink signal through a first path;
a receiver comprising at least one reception antenna module and configured to receive an uplink signal through a second path separated from the first path without a portion overlapped with the first path; and
a controller configured to control the transmitter and the receiver,
wherein:
the transmission antenna module comprises:
a power amplifier provided on the first path and configured to amplify power of a transmission signal;
a transmission filter provided on the first path and configured to generate the downlink signal by filtering a frequency of the transmission signal amplified by the power amplifier; and
at least one transmission antenna provided on the first path and configured to transmit the downlink signal filtered and generated by the transmission filter, and
wherein the reception antenna module comprises:
at least one reception antenna provided on the second path and configured to receive the uplink signal;
a low noise amplifier provided on the second path and configured to low-noise-amplify the uplink signal received by the reception antenna; and
a reception filter provided on the second path and configured to filter a frequency of the uplink signal low-noise-amplified by the low noise amplifier, and
wherein the low noise amplifier is disposed between the reception antenna and the reception filter along the second path along which the uplink signal is received, and

wherein a distance between the reception antenna and the low noise amplifier along the second path is shorter than a distance between the transmission antenna and the power amplifier along the first path.
