An antenna assembly, a terminal device having the antenna assembly, and a method for improving a radiation performance of an antenna are provided. The terminal device includes an antenna assembly, and a controller. The antenna assembly comprises an antenna, a first adjusting unit, a second adjusting unit, and an antenna switch; the controller is configured to control, based on a current working power of the antenna, the antenna switch to select one of the first adjusting unit and the second adjusting unit to be in an enabled state, so that a radiation direction of the antenna can be adjusted by the selected adjusting unit to a radiation direction formed based on the selected adjusting unit.

Antenna assemblies, terminal devices, and methods for improving radiation performance of antenna

A method for processing radio frequency (RF) interference and an electronic device are provided. The method includes the following. Functional components in operating status are determined while an RF signal received by an RF circuit has signal strength lower than a preset threshold. For each functional component, an interference intensity to the RF circuit and a distance to the RF circuit are acquired. For each functional component, an interference value is acquired according to the interference intensity and the distance. A target functional component with an interference value meeting a preset condition is disabled.

Method for processing radio frequency interference and electronic device

The present disclosure provides a method for radio frequency interference processing, comprising acquiring a first signal strength value of the first radio frequency antenna; determining whether the first signal strength value is lower than a preset threshold; and stopping the information display on the first area when the first signal strength value is lower than the preset threshold. The method reduces the interference from display components to radio frequency components, improve the efficiency of radio frequency communication.

A micro-actuator for a head gimbal assembly includes a fixed portion connectable to a suspension of the head gimbal assembly and a movable portion connectable to a slider of the head gimbal assembly. A pair of frame ribs interconnect the fixed portion and the movable portion. A PZT element is mounted to each of the frame ribs. Each PZT element is excitable to cause selective movement of the frame ribs which causes movement of the movable portion to cause movement of the slider. A tongue is fixed to and extends from the fixed portion. The tongue is engagable with a pivot provided on the suspension of the head gimbal assembly. The tongue forms a gap between the movable portion and itself.
