Title:
RADIATION UNIT AND BIPOLAR ANTENNA
Document Type and Number:
WIPO Patent Application WO/2016/127893
Kind Code:
A1
Abstract:
A radiation unit (10) comprises: a square radiation patch (11); a first feeding sheet (12a) and a second feeding sheet (12b), suspended below the square radiation patch (11), the first feeding sheet (12a) being configured to implement +45° polarization, and the second feeding sheet (12b) being configured to implement -45° polarization; a reflector plate (13), located below the first feeding sheet (12a) and the second feeding sheet (12b); and a first cable (14a) and a second cable (14b), an inner conductor (121) of the first cable (14a) passing through the reflector plate (13) and being connected to the first feeding sheet (12a), and an inner conductor (121) of the second cable (14b) passing through the reflector plate (13) and being connected to the second feeding sheet (12b). A distance from the square radiation patch (11) to the reflector plate (13) is a wavelength 0.115 to 0.133, a distance from the first feeding sheet (12a) and the second feeding sheet (12b) to the reflector plate (13) is a wavelength 0.07 to 0.08, and a distance from the first feeding sheet (12a) and the second feeding sheet (12b) to the square radiation patch (11) is a wavelength 0.044 to 0.051. A bipolar antenna comprises an array of the foregoing radiation units. The foregoing radiation unit and bipolar antenna are disposed, so that the miniaturization of an antenna of a base station can be implemented.
