ANTENNA RADIATION UNIT, ANTENNA ARRAY, AND ANTENNA PERFORMANCE ADJUSTMENT METHOD

The present disclosure relates to the technical field of communications. Disclosed are an antenna radiation unit, an antenna array, and an antenna performance adjustment method. The antenna radiation unit comprises a low-frequency radiation unit (1) and a high-frequency radiation unit (2), wherein the low-frequency radiation unit (1) comprises two pairs of dipoles arranged in a bipolarized manner, the distance between any pair of dipoles is less than 0.4 time the wavelength of a center frequency of the low-frequency radiation unit, and the high-frequency radiation unit (2) is embedded in the low-frequency radiation unit (1). In the antenna radiation unit, the antenna array and the antenna performance adjustment method which are provided in the present disclosure, a low-frequency radiation unit is configure to comprise two pairs of dipoles, thereby facilitating an increase in a beam squint and in a sector power ratio indicator of the low-frequency radiation unit; the distance and height of the low-frequency ra
