WIMAX dual polarization base station directional antenna

The utility model discloses a WIMAX bipolar base station directional antenna, including a reflection plate, at least two vibrator components and a microstrip feed network; each vibrator component comprises a surface medium radiation film, a medium feed support film and a vibrator fixing base; the medium feed support film is located between the surface medium radiation film and the vibrator fixing base; the vibrator components are axially fixed on the reflection plate in an equal interval setting through the vibrator fixing bases; the vibrator fixing bases are fixed on the reflection plate optimally through threaded connection; the vibrator components and the microstrip feed network are respectively located on the positive and negative faces of the reflection plate; the microstrip feed network is connected with the medium feed support film; at least a pair of symmetric parasitic elements are symmetrically fixed at the edge of the reflection plate; from the locations of the symmetric parasitic elements, a determined number of vibrator component can be observed; the optimally selected symmetric parasitic elements are rectangular sheet metals with the height corresponding to that of the surface medium radiation film; and the rectangular sheet metals are fixed at the edge of the reflection plate through riveting.
