Abstract: An antenna array for a liquid crystal display able to function without a phase shifter includes at least two antenna units, each with an antenna module and a controlling circuit. The antenna module is at the side of a first substrate, a grounding layer, a feeding portion, a second substrate, and a liquid crystal layer also being included as a stack. The grounding layer and the feeding portion are on sides of the second substrate. The controlling circuit controls rotation of liquid crystal molecules of the liquid crystal layer therein to change a dielectric constant between the grounding layer and the antenna. The operating frequency of each antenna unit is thereby changed and radiation beam or pattern of the antenna array is thereby adjusted.

Abstract: A switch control system including a switch unit and a control unit allows the switch unit to be disposed at any position within an effective radiation range of the control unit. The switch unit transmits an identifier to the control unit when pressed by a user. The control unit is electrically connected to a functional unit, the control unit is used to transmit radio frequency signals and read the identifier of the switch unit, and turn on or off the functional unit according to the identifier as read. A related method is also provided. The switch unit can be installed at any position within the radiation range and the position can be changed at any time.

Abstract: A data sharing method runs on a first electronic device comprising a number of first background pages. Each first background page displays a number of first application icons. The method comprises controlling the first electronic device to communicate with a second electronic device through a communication unit, acquiring second background pages from the second electronic device communicating with the first electronic device, and displaying the acquired second background pages on a display unit of the first electronic device. The method determines whether one second application icon of the second background pages displayed on the first electronic device is moved to one first background page of the first electronic device, and determines the moved second application icon as being a target icon. Data of the target icon from the second electronic device is acquired.

Abstract: An ultrahigh frequency RFID tag antenna with multi-infeed includes an antenna assembly, a baseboard, and a ground plane. The baseboard is located above the ground plane. The antenna assembly is electrically connected to the ground plane. The antenna assembly includes a radiated element, a number of microstrip lines, and a number of tag chips. Each of the tag chips is connected between each two microstrip lines, thereby a microstrip feed loop is formed by each of the tag chips and the each two microstrip lines.
