Active antenna array based on strip line one-to-six power division network

Abstract

The invention provides an active antenna array based on a strip line one-to-six power division network, and aims to solve the problems of large size, low efficiency of a power division network structure and low isolation between branches of an existing antenna array. The active antenna array comprises a strip line one-to-six network, a multi-layer printed circuit board, six antennas arranged on the upper portion of the multi-layer printed circuit board and six radio frequency front ends arranged on the lower portion of the multi-layer printed circuit board. The strip line one-to-six network is located on the middle layer of the multi-layer printed circuit board, and the radio frequency front ends are located on the bottom layer of the printed circuit board, and the antennas are located on the top layer of the printed circuit board. The strip line one-to-six power division network and the radio frequency front ends as well as the the radio frequency front ends and the antennas are connected through metalized strip line micro-strip line connecting holes and antenna micro-strip line connecting holes, so that the overall size can be reduced. The input impedance of the combining port of an unequal power divider is properly selected, so that the line width of each section of strip line of the unequal power divider is moderate, the impedance error of processing is reduced, and the required power distribution ratio is met.

Description

technical field [0001] The invention relates to the field of wireless communication antenna arrays, in particular to an active antenna array based on a stripline-one-six-power-division network. Background technique [0002] With the rapid growth of mobile data demand, the wireless communication capacity needs to be increased urgently. Therefore, the transmission and reception channels of wireless communication equipment are increasing rapidly. At present, most of the wireless communication capacity is expanded through multiple-input multiple-output technology and beamforming technology, but the huge The number of transceiver channels often leads to a larger size of the wireless communication device. Most of the existing antenna arrays are connected by cables between the antenna and the RF front end, which makes the structure redundant and the volume of the communication equipment larger; and when the number of units of the antenna array is not a power of 2, it is generally u...
