| Zusammenfassung: | The utility model provides a circuit board and terminal equipment, and relates to the field of communication, the circuit board is installed on the terminal equipment, the circuit board comprises a body, the body is provided with an electric field concentration area, and the electric field concentration area of the body is provided with at least one conductive connection part; when the circuit board is installed on the terminal device, each conductive connection part is electrically connected with the body and a metal rear shell of the terminal device, so that the electric field concentration area is connected with the metal rear shell through the conductive connection parts, the grounding effect is achieved, and charges in the electric field concentration area are conducted to the outside of the terminal device. The inefficiency mode of the antenna and the increase of dielectric loss caused by overlarge electric field intensity of the electric field concentration area are avoided, the antenna radiation effic |
