Problems solved by technology

Generally speaking, the number of buckling times of the connector is limited. After many times of buckling, its electrical and mechanical properties will gradually deteriorate. In addition, after the buckling, the insertion and extraction force is also limited. When the overall system design is not good, it is easy to cause Connection stability and other issues
[0004] With the development of the fifth-generation mobile communication technology, the operating frequency is getting higher and higher, especially the introduction of the millimeter wave frequency band. This traditional interconnection method is becoming more and more difficult, and the requirements for board-to-board connectors are also very high. It is not conducive to the performance and integration of the whole machine system
In the millimeter wave frequency band, the connector will not only introduce additional loss, but also prone to electromagnetic leakage, which will bring electromagnetic interference to other components in the terminal equipment

Abstract

The invention discloses an LCP material based millimeter-wave antenna system and a mobile terminal. The millimeter-wave antenna system comprises an antenna assembly, the antenna assembly comprises anantenna layer, a substrate layer and a circuit layer, the system is characterized in that the substrate layer is made of an LCP material, the antenna layer and the circuit layer are arranged in two side surfaces, opposite to each other, of the substrate layer, and the antenna layer is electrically connected with the circuit layer. The LCP material serves as the substrate layer, the antenna layer and the circuit layer are integrated, use of a board-to-board connector is avoided, the cost can be reduced, electromagnetic leakage is reduced, and the stability of the antenna system is improved; theLCP material is low is loss, and extra loss caused by a connector can be avoided effectively; and the LCP material is flexible and can be molded by folding, can be integrated with other parts, and occupies small space, and thus, the mobile terminal can be thinner. The antenna system is simple in structure and high in antenna performance.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a millimeter-wave antenna system based on LCP materials and a mobile terminal. Background technique [0002] The development of mobile communication technology pursues to bring users a faster experience. Compared with the fourth-generation mobile communication technology, the emergence of the fifth-generation mobile communication can increase the communication rate by 20 to 100 times. The key factor is that 5G uses mm The wave band can provide a wider frequency bandwidth. In mobile terminal equipment, the key and challenge to realize millimeter wave communication is how to realize millimeter wave antenna and integrate the millimeter wave antenna inside the terminal equipment. Traditionally, the antennas of terminal equipment are mostly independently designed, and then the antennas are connected to the main circuit board of the equipment through board-to-board connectors...
