Abstract

The invention relates to a dual-frequency dual-polarization elevator antenna, which comprises a reflection plate and a radiation unit. The dual-frequency dual-polarization elevator antenna is characterized in that high-frequency oscillators are arranged on the reflection plate in a rectangular array structure; each low-frequency oscillator is in a bowl structure; the low-frequency oscillators are arranged on the reflection plate at the places of the high-frequency oscillators at the four corners of the high-frequency oscillators in the rectangular array; and the high-frequency oscillators at the four corners of the high-frequency oscillators in the rectangular array are coaxially arranged in the bowl-shaped low-frequency oscillators respectively. Through combination of reasonable sizes, the performance of the antenna is improved, and the formed dual-frequency dual-polarization elevator antenna is high in performance, and has the advantages of wide coverage band and high anti-interference capability and the like; and the radiation unit adopts the bowl-shaped low-frequency oscillators, and separator plates are arranged between corresponding radiation units to ensure isolation, horizontal radiation width thereof reaching 90+ / -8 degrees, so that the unit is high in efficiency and simple in structure, and base station coverage range is large.
