Abstract: A mobile device includes a system circuit board, a metal frame, one or more other antenna elements, a display device, a first feeding element, and an RF (Radio Frequency) module. The system circuit board includes a system ground plane. The metal frame at least includes a first portion and a second portion. The metal frame at least has a first cut point positioned between the first portion and the second portion. The metal frame further has a second cut point for separating the other antenna elements from the first portion. The first cut point is arranged to be close to a middle region of the display device. The first feeding element is directly or indirectly electrically connected to the first portion. A first antenna structure is formed by the first feeding element and the first portion.

Abstract: A multi-color chemiluminescent light device is disclosed. The device emits different colors from different construction parts of the flexible outer container through varying the fluorescer types or incorporation ratios in different construction parts. Firstly, the fluorescer is incorporated into the material for forming the outer container so that the outer container will include the fluorescer after being injection molded. If there are two fluorecers respectively incorporated into the outer container and the hollow plug, the whole chemiluminescent light device will emit two lights. Consequently, the outer container can determine the color of light emitted by the chemiluminescent light device to have one single color or multiple colors.
