An isolation barrier for reducing coupling between a transmitting antenna on a platform and a receiving antenna on the same platform. The isolation barrier expands the isolation capabilities of radar absorbing material (RAM) to the low frequency region by integrating dielectric loaded corrugations with the RAM. The isolation barrier includes a plurality of corrugations, each including a channel with two conductive walls and a conductive base, having a depth greater than a quarter of the wavelength corresponding to the low-frequency limit of the shared operating frequency band of the transmitting antenna and the receiving antenna. A layer of radar absorbing material (RAM) covers the corrugations.

The present disclosure provides an electronic device, a mobile terminal and an antenna assembly. The electronic device includes: a case defining an accommodating groove; a movable support slidably connected to the case, and capable of moving out of or retracting into the accommodating groove; and a first antenna installed on the movable support. Since the first antenna may be ejected out of the accommodating groove along with the movable support, influence of other components disposed inside the electronic device on the first antenna may be reduced. Thus, the implementation of the present disclosure may improve antenna performance of the electronic device.

An electronic device is provided. The electronic device includes a first electronic component, a second electronic component, a holder, and an antenna assembly. The second electronic component is slidably coupled to the first electronic component. The holder is coupled to the second electronic component and inserted into the first electronic component. The antenna assembly includes a radio frequency (RF) module, an antenna radiator, and an RF cable. The RF module is disposed in the first electronic component. The antenna radiator is disposed in the second electronic component. An end of the RF cable is coupled to the antenna radiator and the holder, and another end of the RF cable is coupled to the radio frequency module. The RF cable is retracted and stretched when the holder is driven to slide by sliding the second electronic component. A control method of the electronic device is also provided.

A Planar Inverted-F Antenna, PIFA, comprises a sheet of conductive material including first, second, third and fourth contiguous sections, the first and third sections extending orthogonally away from the second section and the fourth section extending away from the third section. The sections are folded relative to one another to define a volume with a height of the second section, a width of the second section and a depth of the third section extending away from the second section. A supporting pin and a feed pin extend from the second section along an outer edge. A supporting leg extends from either the third or fourth sections, the supporting leg lying outside the plane of the supporting pin to support the PIFA when mounted on a printed circuit board, while allowing components to at least partially occupy the volume under the PIFA.

The embodiments of the present disclosure provide positions of an antenna of a mobile communication device in a location that places the antenna at a spaced distance from a user and/or the brain of the user to reduce the amount of RF energy that impinges on the brain of the user when the mobile communication device is in use and held near the face of a user.

An electronic device is provided. The electronic device includes a metal frame, a circuit board, a first connection structure, and an antenna module. The metal frame is provided with a first contact portion extending outwardly from an inner surface of the metal frame. The first connection structure includes a first resilient piece, the first resilient piece has a first end and a second end opposite to the first end, the first end of the resilient piece is electrically coupled with the first contact portion via abutting against the first contact portion. The antenna module disposed on the circuit board is electrically coupled with the second end of the first resilient piece extending through the circuit board, and is electrically coupled with the metal frame via the first resilient piece, such that the metal frame is operable to be antenna resonating elements of the antenna module.

An antenna enables compact and robust multiband operation of portable radios. According to some embodiments, the antenna includes: a first rolled conductive strip having a first section with overlap between successive turns of the first conductive strip and a second section with no overlap between successive turns of the first conductive strip, the first section having an insulating layer between the overlapping successive turns of the first conductive strip; a second rolled conductive strip; and a flexible sheet to which both the first conductive strip and the second conductive strip are bonded.

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 device includes a first nonconductive supporting element, a second nonconductive supporting element, and an antenna structure. The first nonconductive supporting element and the second nonconductive supporting element are adjacent to each other. The first nonconductive supporting element and the second nonconductive supporting element have different heights. The antenna structure is formed on the first nonconductive supporting element and the second nonconductive supporting element. The antenna element includes a feeding connection element, a first radiation element, and a second radiation element. The feeding connection element is coupled to a feeding point. The first radiation element and the second radiation element are coupled to the feeding connection element. The feeding connection element is disposed between the first radiation element and the second radiation element.
