TECHNICAL FIELD
[0001] The utility model relates to the technical field of WiFi antenna, specifically relates to a WiFi antenna applied to wearable equipment. BACKGROUND
[0002] Wearable equipment is more and more miniaturized, and the space left for the antenna in wearable equipment is smaller and smaller. However, the performance requirement of wearable equipment for the antenna is higher and higher, especially the positioning performance requirement is extremely high, including positioning accuracy and positioning speed. At present, indoor positioning mainly relies on WiFi positioning, and the accuracy and speed of WiFi positioning are related to the performance of WiFi. The performance of WiFi is not only reflected in the efficiency of the antenna, but also in the directivity of the antenna. Due to the miniaturization of the structure of wearable equipment, the structure of wearable equipment is more and more complex, and it is difficult to control the directivity of the antenna, especially the wearable equipment contacts a part of the body, such as a watch worn on the hand. The current commonly used antenna scheme does not consider the directivity of the WiFi antenna, so the wearable equipment adopts a single antenna scheme in the WiFi design, which will cause the antenna to have a zero point in some directions of the required direction, such as a watch worn on the hand, which has a zero point in some areas of the front of the watch screen. If the application state is just in this direction, the positioning speed and accuracy at this time will be very poor. In order to optimize the directivity of the antenna, a dual antenna scheme can be used. The main difficulty of the dual antenna scheme is the layout of the dual antenna and how to combine the dual antenna, so as to realize the omnidirectionality of 2.4G WiFi performance in the required area.
