The invention provides electronic equipment which comprises a first antenna, a second antenna, a first phase shift network, a first matching network, a second phase shift network, a second matching network, a parallel susceptance network and a first filter network, the first end of the first phase shift network is electrically connected with the first antenna, and the second end of the first phaseshift network is electrically connected with a first feed port through the first matching network; the first end of the second phase shift network is electrically connected with the second antenna, and the second end is electrically connected with the second feed port through the second matching network; the second end of the first phase shift network is electrically connected with the second endof the second phase shift network through the parallel susceptance network; wherein the first filtering network is used for filtering signals in a first frequency band range, and the first frequencyband range at least comprises a part of working frequency band range of the second antenna and does not comprise the working frequency band range of the first antenna. According to the embodiment of the invention, the decoupling of the frequency overlapping frequency bands of the multi-frequency antenna can be realized, the influence of multiple other frequency bands is greatly weakened, and the isolation of other frequency bands and the antenna performance are ensured.
Description
technical field [0001] The present invention relates to the technical field of communication equipment, in particular to an electronic equipment. Background technique [0002] With the development of communication technology, Multiple-Input Multiple-Output (MIMO), as a core technology of 5G (fifth generation mobile communication), has been paid more and more attention. Wider and wider, more and more in number. In the terminals we use, such as smart phones, tablets, notebooks, etc., their physical size is limited, which inevitably leads to a contradiction between limited design space and more antenna requirements. The reduction of the antenna design space means the reduction of the spacing between the antennas. Generally speaking, the isolation between the antennas will decrease, and the antenna radiation performance will be affected. [0003] Various decoupling methods have been proposed in academia, one of which is parasitic decoupling structure, defect ground structure, ...
