Problems solved by technology

However, since the first electronic device includes an antenna component, when the docking station is electrically connected to the first electronic device and the second electronic device, the integrated ground layer formed by the first ground layer and the second ground layer will be separated from the first ground layer. The ground wire of an electronic device is electrically connected, resulting in the expansion of the ground area of ​​the first electronic device, which in turn leads to a decrease in antenna gain, which does not meet the requirements of product design for antenna gain

Abstract

A circuit board is provided. A first grounding layer and a second grounding layer are formed on the circuit board; the first grounding layer and the second grounding layer are set in a mutually insulated manner; a high-pass element is welded on the circuit board; the high-pass element is electrically connected between the first grounding layer and the second grounding layer; and the high-pass element is used for providing a high-frequency signal return current passageway, so that high-frequency signal return current received by the first grounding layer can flow to the second grounding layer through the high-pass element. The invention also provides an extension seat.

Description

technical field [0001] The invention relates to a circuit board and an extension seat. Background technique [0002] Two electronic devices (such as a first electronic device and a second electronic device) are usually electrically connected through an extension socket, so as to transmit data of the second electronic device to the first electronic device through the extension socket. Wherein the first electronic device includes an antenna component. A circuit board is arranged inside the extension base, and a first ground layer and a second ground layer which are insulated from each other are arranged on the circuit board, wherein, when the extension base is electrically connected to the first electronic device and the second electronic device, the first ground layer and the second The ground wire of the first electronic device is electrically connected, and the second ground layer is electrically connected with the ground wire of the second electronic device. And when the...
