摘要： An antenna apparatus used in an electronic device having a flexible display that can be bent at a rotating shaft and that includes a primary screen and a secondary screen respectively configured on two sides of the rotating shaft. The antenna apparatus includes a first metal strip disposed on the primary screen frame close to one end of the rotating shaft, and a second metal strip disposed on the secondary screen frame close to the same end of the rotating shaft. The first metal strip is implemented as a plurality of antennas through dual-feed design. When the flexible display is in a folded state, the second metal strip is coupled to the first metal strip to generate radiation and is used as a parasitic antenna of the first metal strip.

摘要： A method for controlling a specific absorption rate (SAR) of a wireless communications device and a wireless communications device, and the wireless communications device includes a first antenna and a second antenna. The method includes transmitting, by the wireless communications device, a radio frequency signal using the first antenna, and stopping using the first antenna and starting transmitting the radio frequency signal using the second antenna when transmit power of the first antenna is greater than first preset power and a first time period elapses to enable the wireless communications device to meet an SAR standard. There is no backoff of antenna transmit power in a process of controlling the SAR of the wireless communications device. Therefore, communication quality of the wireless communications device is ensured while the SAR standard is met.

摘要： A broadside antenna includes a first radiation element and a second radiation element arranged at an interval, a first grounding element and a second grounding element arranged at an interval, and a first excitation element. A first gap is formed between the first radiation element and the second radiation element. The first excitation element includes a first feeding structure and a first extension stub that are arranged at an interval. The first feeding structure includes a first feed-in part connected to a feed source. The first extension stub is located on a side of the first feeding structure adjacent close to the first feed-in part. The first extension stub includes a first grounding part adjacent to the first feed-in part. The first grounding part is connected to the grounding surface.

摘要： A wearable device includes a metal frame, a printed circuit board PCB, and a first feeding element, where a slot is formed between the metal frame and the PCB. The metal frame includes a first feed point, a first ground point, and a second ground point, and the metal frame is grounded at the first ground point and the second ground point. The metal frame is divided into a first area and a second area by the first ground point and the second ground point, and a circumferential length corresponding to the first area is greater than a circumferential length corresponding to the second area. The first feed point is disposed in the first area, and a distance between the first feed point and the first ground point along the metal frame is less than one third of the circumferential length corresponding to the first area.
