A W-CDMA system having a plurality of antenna sharing apparatuses each having an LNA (Low Noise Amplifier) for receiving a first reception signal for a space diversity from a transmission-reception antenna and separately outputting it to a first and a second paths and a band-pass filter filtering a second reception signal for the space diversity, wherein one antenna sharing apparatus connects a second path of each antenna sharing apparatus to an input terminal of a band-pass filter of a different antenna sharing apparatus in case of increasing a frequency allocation (FA). In case of using a plurality of radio frequency band (FA) in the WLL-CDMA system, the antenna can be shared by a simple cable connection, so that the number of antenna and components required for additionally installing the antenna can be reduced. |
