First Claim
1. A radio frequency control circuit of a base station of a mobile communications system, comprising:
- a transmitting coupler for branching a high-power carrier signal in transmission process, the transmitting coupler being connected between a transmitting side power amplifier and transmitting antenna;
a receiving coupler for inserting a receiving signal in reception process, the receiving coupler being connected between a receiving side splitter and low noise amplifier;
an optical antenna interface for performing mutual conversion between an electrical signal and optical signal in the transmission/reception process of carrier signal, the optical antenna interface being connected to the transmitting and receiving couplers;
an optical antenna section connected to the optical antenna interface in a radial manner, the optical antenna section including a plurality of optical antennas; and
a dispersion antenna section correspondingly connected to the optical antenna section, the dispersion antenna section including a plurality of dispersion antennas.

Abstract
The radio frequency control circuit of the base station of a mobile communications system is constructed in a manner that the transmitting coupler branching the transmission signal to the shadow region is connected between the transmitting side power amplifier and transmitting antenna, and the receiving coupler inserting the signal received from the shadow region is connected between the receiving side low noise amplifier and splitter, to cover the shadow region using a simplified circuit configuration without a separate hardware. Therefore, a signal is transmitted by the optical antenna to a shadow region located at a long distance through the optical cable, and the signal is transmitted by the dispersion antenna to a shadow region located at close range through the coaxial cable, to provide radiocommunication service to a mobile located in the shadow region without establishing a base station in the shadow region.
