Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present disclosure.

The GPS antenna structure of conventional L5 frequency channel is on the metal frame for the GPS antenna of L5 frequency channel can obtain better antenna efficiency, but can occupy more antenna setting region, and the improvement of the difficulty is brought for other structure arrangements such as other important communication antennas of LTE, WIFI. Particularly, as the 5G antenna system is increasingly applied to electronic devices, the area of the electronic device where the conventional bezel is used to arrange the antenna radiator is less and less. Conventional L5 band GPS antennas are mounted on a motherboard, circuit board, or chassis, such that the performance of the antenna is limited by the size of the clearance area around the antenna. Since the operating band of the L5 band antenna is low, the L5 band antenna requires a larger antenna clearance area than the L1 band antenna. As electronic devices become thinner and lighter, the antenna clearance area of the L5 band cannot be too large. Therefore, the efficiency of the radiator of the L5 band antenna on the motherboard, or on the circuit board or on the support, is often very low, typically not more than-15 dB. Therefore, in order to improve the requirement of the electronic device that the arrangement of multiple antennas can be met and the requirement of the increase of the antenna clearance area can be met, an antenna radiator needs to be arranged on the structure except for the frame, the main board, the circuit board and the support in the electronic device.
