Abstract
A grounding structure is described in an embodiment of the present disclosure, which is applied to a rotary wireless access terminal, the wireless access terminal at least includes that: a structural part, as well as a main board and metal rotating shaft, which are arranged in the structural part, of the wireless access terminal, the metal rotating shaft is connected with an external interface of the wireless access terminal, wherein the grounding structure includes a metal dome and an insulating film; and one end of the metal dome is connected with the metal rotating shaft, while the other end is coupled to ground on the main board through the insulating film. A rotary wireless network card based on the above grounding structure is also described in an embodiment of the present disclosure. By the technical solutions of the embodiment of the present disclosure, an interference loop effect formed by a radio frequency current flowing through the main board may be effectively eliminated, the problem of poor low-frequency performance of a built-in antenna is effectively solved, and sensitivity of a low-frequency antenna is improved.
