Abstract

The present invention provides a dual-antenna decoupling structure and electronic equipment, wherein the dual-antenna decoupling structure includes: a circuit board; a first antenna and a second antenna arranged on the circuit board and connected to the circuit board; The antenna and the second antenna are coupled to each other; at least one decoupling structure disposed on the circuit board and between the first antenna and the second antenna, the decoupling structure is grounded through a connection component. The double-antenna decoupling structure provided by the present invention reduces the absolute amount of energy reaching the other antenna, thereby improving the isolation between the two antennas, improving the radiation efficiency, and effectively reducing the envelope correlation coefficient between the two antennas , so that the antenna can better realize the 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...
