Title:
ANTENNA RADIATION UNIT, ANTENNA ARRAY, AND ANTENNA PERFORMANCE ADJUSTMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2024/120091
Kind Code:
A1
Abstract:
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 radiation unit are reduced, thereby facilitating an increase in a beam tracking indicator; and diagonal arraying is performed, thereby facilitating an increase in a beam squint indicator. The antenna radiation unit, the antenna array and the method are applicable to multi-frequency antennas, and effectively improve antenna pattern indicators.
