Abstract: This application provides an antenna system and a wireless device, and pertains to the field of communications technologies. In this application, a decoupling resonator is connected to a first antenna, and a resonance frequency of the decoupling resonator is within an operating frequency band of a second antenna, so that the decoupling resonator can resonate within the operating frequency band of the second antenna. The decoupling resonator reduces coupling between the first antenna and the second antenna, and isolation between the first antenna and the second antenna is improved.

Abstract: An antenna has a reflector and an active element. The reflector includes a multi-segment metal structure having a length within a first value range. The multi-segment metal structure includes a first metal structure connected to a second metal structure. A PIN diode is disposed on the first metal structure. The first metal structure is parallel to a polarization direction of the active element. The second metal structure is perpendicular to the first metal structure.
