Problems solved by technology

In some applications, due to the need for grounding, a metal reinforcement board must be used. At high frequencies, the signal line vias of the flexible board will couple with the metal reinforcement board, resulting in signal line impedance mismatch. Currently, the available method is to make the vias into Blind holes reduce coupling, but blind holes are not the best solution due to their large size will affect the layout of the connector area

Abstract

The invention discloses an antenna system with a built-in MIMO. The antenna system is composed of flexible board B2B regions, a flexible board, metal reinforcing boards, opening-free metal reinforcingboards, and metal reinforcing boards which right face the openings of via holes, wherein two via holes are formed in each metal reinforcing board which right faces the openings of the via holes, twosignal lines are arranged on one sides of the flexible board B2B regions and connected to an inner layer through the via holes, and opening treatment is conducted on the positions, right facing the via holes, of the metal reinforcing boards. The antenna system with the built-in MIMO can overcome the problems of mismatch and performance loss of a transmission line under a high-frequency transmission condition caused by coupling between via holes and metal reinforcing boards in an existing FPC transmission line design; and the influence of the reinforcing boards on the via holes can be reduced in a mode of forming openings at positions corresponding to the via holes, and the performance of the transmission line is improved.

Description

technical field [0001] The invention relates to the technical field of antenna systems, in particular to an antenna system with built-in MIMO. Background technique [0002] With the advent of the 5G communication era, the application of terminal MIMO antennas and millimeter-wave antennas is becoming more and more popular. As an excellent integration platform, FPC (flexible circuit board) can integrate multiple radio frequency signal transmission lines and antennas on one FPC at the same time. Compared with traditional Using multiple coaxial cables to feed signals to the MIMO antenna greatly saves space. However, when designing high-frequency transmission lines, due to the design limitations of the signal line via area of ​​the flexible board connector (B2B), the signal line impedance mismatch usually occurs, which increases the transmission loss. [0003] In the B2B area, the flexible board connection line needs to mount a reinforcement board on the back of the connector to...
