A mobile device includes a ground element, a radiation element, a first short-circuited element, a second short-circuited element, and a switch element. The radiation element has a feeding point, a fixed grounding point, and a switchable grounding point. The fixed grounding point is coupled through the first short-circuited element to the ground element. The switchable grounding point is coupled through the second short-circuited element and the switch element to the ground element. An antenna structure is formed by the radiation element, the first short-circuited element, the second short-circuited element, and the switch element.

An electronic device includes: a housing; a display; and an extendable phased array antenna structure integrated with the housing and moveable relative to the housing between a retracted position and an extended position. The extendable phased array antenna structure comprises an array of antenna elements that are configured to form a beam in a determined direction.

A wireless control device, such as a system controller for a load control system, may comprise a light-transmissive cover for an antenna that may be illuminated to provide feedback to a user of the load control system. The light-transmissive cover may receive light energy from a light-generating circuit to provide a visible display of the light energy. The wireless control device may be mounted to, for example, a ceiling, and the light-transmissive cover may extend from the wireless control device (e.g., down from the ceiling). The light-transmissive cover may be viewed by a user at large viewing angles and at a distance away from the wireless control device, which may simplify and improve reliability of commissioning of the load control system as well as speed up troubleshooting of the load control system after commissioning is completed.

A mobile terminal includes a body, and a flexible display screen disposed on the body. The flexible display screen is configured to be switched between an expanded state and a retracted state. A primary antenna is disposed within the body, and a spare antenna for replacing the primary antenna is disposed at an edge of the flexible display screen. The method includes: controlling the primary antenna to be in a working state and the spare antenna to be in a non-working state when the flexible display screen is in the retracted state; and controlling the primary antenna to be in a non-working state and the spare antenna to be in a working state when the flexible display screen is in the expanded state.

An electronic device is provided. The electronic device includes a first housing comprising a first space and comprising a conductive portion, a second housing comprising a second space and slidably coupled to the first housing, a flexible display disposed to be supported by the first housing and the second housing and having a display area expanding when being transitioned from a slide-in state to a slide-out state, and a wireless communication circuit disposed in the first space and configured to transmit or receive a wireless signal in a designated frequency band via the conductive portion, wherein the electronic device comprises a conductive stub disposed in the second housing and disposed to be connectable through capacitive coupling to at least a part of the conductive portion in the slide-in state.

A computer implemented method, system and device are provided. The method transmits an energizing signal from an external antenna, coupled to a local external device (LED), to an implanted antenna of a passive implanted medical device (PIMD). The energizing signal is transmitted while the external antenna is at first and second positions. The method receives, at the external antenna, first and second energy transfer characteristic (ETC) values associated with the first and second positions, respectively. The method is under control of one or more processors configured with program instructions. The method analyzes the first and second ETC values to determine a difference therebetween. The method provides an energy transfer level (ETL) indicator based on the difference between the first and second ETC values. The ETL indicator provides feedback regarding a degree of energy transfer associated with at least one of the first and second positions.
