The invention relates to a metal ring watch antenna suitable for a full-band network. The metal ring watch comprises a plastic housing, a metal ring / frame and a PCB board. The metal ring / frame is usedas the main antenna of the metal ring watch antenna. The metal ring watch antenna further comprises a GPS antenna arranged under the screen of the watch and integrated at the FPC of the screen. The GPS antenna is provided with a feeding point. The WIFI antenna is arranged on the surface of the plastic case of the watch. The WIFI antenna is provided with a feeding point and a ground point. A PCB is arranged below the screen. The main antenna is provided with a feeding point and at least three grounding points, one of the three grounding points of the main antenna is connected with the ground of the PCB board through a radio frequency switch, and the remaining grounding points are connected with the ground of the PCB board. The ground point of the WIFI antenna is connected to the ground plane of the PCB. The resonant frequency of the watch antenna can well cover GPS & WIFI & BT and 3G / 4G network, and can meet the requirements of the work frequency band of the watch.
Description
technical field [0001] The invention relates to the technical field of mobile communication, in particular to a metal ring watch antenna suitable for a full frequency band network and a metal ring watch with the watch antenna. Background technique [0002] With the development of intelligent hardware, the function of the hardware becomes more and more powerful, and the size of the mobile terminal equipment becomes smaller and smaller. Traditional electronic products can have more functions by inheriting intelligent hardware. For example, in addition to the function of displaying the time of a traditional watch, a smart watch can also have the function of answering calls. General watches with answering function are larger and thicker in size, so the new mobile terminal equipment needs to have a very attractive appearance to make users like it. These products usually have a thin profile, and it is more desirable that these products can have metal parts, especially metal ring...
