SEAMLESS SEALED-FRAME ANTENNA AND WIRELESS COMMUNICATIONS DEVICE

摘要

Disclosed are an antenna apparatus and a wireless terminal. The antenna apparatus comprises a feeding portion, a grounding portion, and a sealed frame. The sealed frame encloses the main body of the wireless terminal. The feeding portion, the grounding portion and the sealed frame are electrically connected. The sealed frame correspondingly forms a first current circuit and a second current circuit with the feeding portion and the grounding portion. The first current circuit and the second current circuit form resonance. According to the antenna apparatus and the wireless terminal provided in embodiments of the present invention, a seam does not need to be arranged in the sealed frame of a wireless communications terminal with a metal appearance, and through the position of a feeding portion of a radio frequency feeder, the influence of a sealed environment to radiation performance of an antenna when a seam is not arranged in the sealed frame is reduced, thereby enhancing the antenna performance and improving the user experience.
