Abstract

The invention relates to a 5G base station oriented antenna array based on an integrated design of an antenna array and a power-dividing feeding network, which solves the defect that the performance of a dual-polarized 5G base station antenna array fails to meet the practical requirement compared with the prior art. An antenna array radiation component comprises a metal grounding plate printed onthe upper surface of a microwave dielectric substrate, antenna units penetrate through the metal grounding plate and are embedded on the microwave dielectric substrate, and the number of the antenna units is four. According to the antenna array, conventional electromagnetic dipoles are replaced by inverted-L-shaped radiation copper plates so that the impedance bandwidth of the antenna units is improved; besides, a conventional metal copper floor is replaced by the microwave dielectric substrate, and the power-dividing feeding network is printed on the microwave dielectric substrate to replacea conventional coaxial cable feeding network so that the size of the antenna array is reduced, the antenna array is more easily assembled, debugged and integrated, and an EBG structure with a decoupling effect is coated in the same plane of the power-dividing feeding network so that the isolation degree of the array is further improved.

Description

technical field [0001] The invention relates to the technical field of base station antenna arrays, in particular to a 5G base station antenna array and its design method based on the integrated design of the antenna array and power distribution and feeding network. Background technique [0002] As the transmitting and receiving equipment of radio communication, the antenna directly affects the quality of the radio signal. Therefore, the antenna occupies an extremely important position in radio communication. An antenna system with a reasonable structure and excellent performance can minimize the requirements on the entire wireless system, thereby saving system costs and improving the performance of the entire communication system. [0003] The electromagnetic dipole antenna uses a Γ-shaped feed strip to excite the electric dipole and the magnetic dipole at the same time, which can achieve wide impedance matching. Unidirectional, so most base station antennas on the market ...
