Summary:A radio frequency repeating system for wireless communication using a cross dipole array circular polarization antenna is provided to maximize a difference of left/right of a main lobe to minimize a sub lobe copied to a rear side of an antenna, thereby minimizing interference due to reflecting waves. A circular polarization link antenna(2310) transmits and receives a radio signal with a base station system. A circular polarization service antenna(2320) transmits and receives a radio signal with a mobile communications terminal. A repeating device(2330) amplifies a signal received from the circular polarization link antenna. The repeating device transmits the amplified signal to the circular polarization service antenna. The repeating device amplifies the signal through received through the circular polarization service antenna and transmits the amplified signal to the circular polarization link antenna.
