Abstract: An antenna structure includes a ground element, a first radiation element, a second radiation element, a third radiation element, and a nonconductive support element. The first radiation element is coupled to a first grounding point on the ground element. The second radiation element has a feeding point. The second radiation element is adjacent to the first radiation element. The third radiation element is coupled to a second grounding point on the ground element. The third radiation element is adjacent to the second radiation element. The first radiation element, the second radiation element, and the third radiation element are disposed on the nonconductive support element. The second radiation element is at least partially surrounded by the first radiation element. The third radiation element is at least partially surrounded by the second radiation element.

Abstract: A wearable device includes a ground element, a first radiation element, a second radiation element, a third radiation element, a fourth radiation element, and a fifth radiation element. The first radiation element has a feeding point, and is coupled to a first grounding point on the ground element. A slot region is surrounded by the first radiation element and the ground element. The second radiation element is coupled to a second grounding point on the ground element. The third radiation element is coupled to the second grounding point. The third radiation element and the second radiation element substantially extend in opposite directions. The fourth radiation element and the fifth radiation element are disposed inside the slot region. An antenna structure is formed by the first radiation element, the second radiation element, the third radiation element, the fourth radiation element, and the fifth radiation element.

Abstract: A case, such as a suitcase or a photo case, for holding an object at an exterior thereof includes a case body and a hinge edge frame arrangement. The hinge edge frame arrangement includes a first edge frame, a second edge frame and a resilient element. The first edge frame is extended along the utility edge of the case body to retain a utility panel in position, wherein the first edge frame has an elongated holding slot formed between an outer and an inner wall along a utility edge. The second edge frame includes an elongated pivot arm, having an enlarged end portion, pivotally received in and extended along the holding slot of the first edge frame, and a clipping member extended from the pivot arm, wherein the clipping member is adapted to fold between a clipping position and a releasing position for detachably clipping an object by the clipping member.
