Abstract: An antenna structure is provided. The antenna structure includes a first metal element and a second metal element. The first metal element includes a first slot that extends along a first direction to form an elongated shape. The second metal element includes a first branch portion including a first open section and a part section. The first open section extends along the first direction to form an open end, and the part section extends along a second direction to form an open end. A projection of the part section and a projection of the first slot are partially overlapped when being observed along a third direction. The first direction, the second direction, and the third direction are perpendicular to one another.

Abstract: A card-type memory package is revealed, primarily comprising a substrate, a plurality of gold fingers, at least a memory chip, an LED chip, and an encapsulant. The memory chip and the LED chip are disposed on an encapsulated surface of the substrate with the LED chip adjacent to a rear side of the substrate. The gold fingers are attached to the substrate adjacent to a front side of the substrate. The encapsulant is formed on the encapsulated surface to encapsulate the memory chip and the LED chip with the gold fingers exposed. Therefore, the card-type memory package has the LED indication of reading and writing information with simplified assembling processes.
