Abstract

The invention provides a double-antenna decoupling structure and an electronic device. The double-antenna decoupling structure comprises a circuit board; a first antenna and a second antenna which arearranged on the circuit board, are connected with the circuit board and are coupled with each other; and at least one decoupling structure arranged on the circuit board and located between the firstantenna and the second antenna, wherein the at least one decoupling structure is grounded through a connecting assembly. According to the dual-antenna decoupling structure provided by the invention, the absolute quantity of energy reaching the other antenna is reduced, so that the isolation degree between the dual antennas is improved, the radiation efficiency is improved, the envelope correlationcoefficient between the dual antennas is effectively reduced, and the antenna can better realize a multiple-input multiple-output effect.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a dual-antenna decoupling structure and electronic equipment. Background technique [0002] 5G (5th generation mobile networks, fifth-generation mobile communication technology) The working frequency band and number of antennas in electronic equipment have increased sharply. When the size of electronic equipment does not change much, the distance between antennas becomes very close. It will cause the isolation degree between the antennas to decrease, thereby affecting indicators such as antenna efficiency and ECC (Envelope Correlation Coefficient, envelope correlation coefficient). [0003] In electronic devices with plastic casings, antennas are usually made using FPC (Flexible Printed Circuit) or LDS (Laser-Direct-structuring) processes. Compared with electronic devices with metal frames, the antenna design It is more flexible and changeable, and the decoupling met...
