<p>The present invention relates to an apparatus for sharing antennas of wireless access node systems in a wireless communication network having A and B wireless access node systems, each including at least one transceiver for processing transmitted and received signals in at least one signal band, and is characterized by comprising: directional coupler module A and multiple input multiple output (MIMO) coupler A. The directional coupler module A passes the transmitted signal, which is provided via a first transception path among MIMO paths of at least one transceiver of the A wireless access node system, using full reflection properties, and passes the transmitted signal, which is provided via a second transception path among MIMO paths of the at least one transceiver of the B wireless access node system, mixes the two signals, and outputs the result to an antenna side of the A wireless access node system. The MIMO coupler A includes a received signal processing circuit which provides a portion of the received signal of the antenna of the A wireless access node system via the second transception path of the B wireless access node system.</p> |
