Abstract

The present invention provides a coupling structure for a wireless communication device, the wireless communication device includes a first grounding unit, a second grounding unit and an antenna, the coupling structure is arranged between the first grounding unit and the second grounding unit, The coupling structure includes a first coupling part, a second coupling part and a third coupling part, the first coupling part, the second coupling part and the third coupling part form a filter, and the antenna receives and / or transmits the first frequency band and the first frequency band For wireless signals of two frequency bands, the filter blocks the signals of the first frequency band between the first grounding unit and the second grounding unit, and allows the signals of the second frequency band to pass. The invention also provides a wireless communication device with the coupling structure.

Description

technical field [0001] The invention relates to a coupling structure and a wireless communication device with the coupling structure. Background technique [0002] In order to meet the demand for a large screen of a mobile phone, the size of the display screen of the mobile phone becomes larger. However, for foldable mobile phones, when the mobile phone is in the open state, the large display makes the ground plane too long, which affects the low-frequency characteristics of the antenna, especially for the low-frequency band (700-960MHz) covered by the 4G frequency band more obvious. At the same time, with the development trend of thinner and lighter mobile phones, the headroom area of ​​mobile phones is getting smaller and smaller. Therefore, in the limited clearance area, it is necessary to effectively improve the antenna bandwidth and efficiency in the low frequency band. Contents of the invention [0003] In view of this, it is necessary to provide a coupling struct...
