Problems solved by technology

Although the current mobile communication antennas mostly use mutually orthogonal radiating elements to reduce the correlation between co-polarized and differently polarized radiating elements, due to the limitations of the radiating element's own polarization purity, frequency band, bandwidth, beam width, etc. , the cross-polarization discrimination rate is often the difficulty in the development of multi-antenna arrays

Abstract

The invention provides a curved reflector type multi-antenna array which comprises more than one reflectors, a row of antenna radiation units are mounted on each reflector, and the antenna radiation units are electrically connected with one another through a feed network arranged on the backs of the reflectors; and the multi-antenna array can provide positive or negative 45 degrees of dual-polarization signal coverage. Because the reflectors of the multi-antenna array are wavy, the distances from the feed centers of the radiation units to the reflectors are equal, and consequently, the cross polarization discrimination rate of the multi-antenna array is increased.

Description

technical field [0001] The invention relates to the technical field of mobile communication array antennas, in particular to a multi-antenna array in the form of a bent reflector. Background technique [0002] In the field of wireless mobile communication technology, the antenna as a terminal is mainly used for transmitting and receiving signals. At present, the wireless environment is relatively complex. During the propagation of electromagnetic waves in the wireless channel, due to the reflection, refraction, and loss of the ground surface and obstacles, polarization deflection will occur. For this reason, antennas for mainstream mobile communications are mostly composed of two groups of ±45° dual-polarized radiation units with mutually orthogonal polarization directions. Each group of radiation units satisfies the same array characteristics, so it can effectively deal with the Unfavorable factors such as polarization deflection. At the same time, since the correlation b...
