Signal distributing/combining apparatus in antenna apparatus of mobile communication base station

A signal distributing/combining apparatus in an antenna device of a mobile communication base station, the signal distributing/combining apparatus comprising:

• a circuit board configured to have an upper surface formed with a signal distributing/combining conductor pattern for a high frequency signal distributing/combining operation;
• and
• a support plate configured to have an upper mounting surface of a size corresponding to the circuit board, to mate with the circuit board so that an underside of the circuit board is in close contact with the upper mounting surface for supporting the circuit board, and to fixedly mate with the antenna device at a reflection plate on a bottom side of the support plate,
• wherein the support plate is provided with a plurality of cable holders for supporting and fixating coaxial cables for signal transmission, which are connected from outside of the signal distributing/combining apparatus, the signal distributing/combining conductor pattern is formed with a plurality of signal input/output portions, and the plurality of cable holders is formed on the signal distributing/combining conductor pattern at portions corresponding to at least some of the plurality of signal input/output portions, the cable holders having a structure formed elongated longitudinally and corresponding to outer conductors of the coaxial cables in order to mount the coaxial cable by inserting the outer conductors.
