The utility model provides an improved broadband high-gain miniaturized dual-polarized log-periodic antenna, which comprises an antenna main body, and a plurality of dual-polarized antenna oscillators, a broadening antenna oscillator and a parasitic radiation assembly which are arranged on the antenna main body, the parasitic radiation assembly comprises a high-frequency parasitic radiation ring used for improving the high-frequency gain of the antenna and a low-frequency parasitic radiation ring used for improving low-frequency standing waves and improving the low-frequency gain of the antenna. Due to the fact that the antenna oscillator and the parasitic radiation assembly are broadened, the low-end frequency of the antenna can be broadened, and the broadband requirement is met through the broadband characteristic of the dual-polarization logarithmic-circle-shaped antenna and further broadened low frequency; in addition, due to the parasitic radiation assembly, the gain of the antenna can be improved throug
