The utility model relates to a shunt-fed combined broadband antenna. The shunt-fed combined broadband antenna comprises a low frequency upper oscillator, a low frequency lower oscillator, a high frequency upper oscillator, a high frequency lower oscillator, a low frequency matcher and a feed port. The high frequency upper oscillator is arranged at the periphery of the lower part of the low frequency upper oscillator coaxially, the high frequency lower oscillator is arranged at the periphery of the upper part of the low frequency lower oscillator coaxially, and the low frequency upper oscillator is connected with the upper end of the low frequency lower oscillator correspondingly via the feed port. The high frequency upper oscillator and the high frequency lower oscillator are arranged at the upper and lower parts of the feed port correspondingly to form a high frequency dipole antenna, and the low frequency matcher is arranged on the low frequency upper oscillator in the high frequency upper oscillator. According to the utility model, the shunt feed is realized by arranging the high and low frequency band oscillators coaxially and by the intermediate feed port, the circuit impedance matching is realized by matching an antenna matcher, and the high and low frequency band use and the stable usage performance of the antenna are guaranteed.
