The antenna module 233 is, for example, a digital TV antenna module pivotally connected to the cover 231, so that the antenna module 233 can be rotated relative to the cover 231 to be deployed. Please refer to FIG. 1B, which is a schematic diagram showing the antenna module in FIG. 1A rotated relative to the cover body. The unfolded antenna module 233 is used to support the handheld electronic device 200, and the unfolded antenna module 233 is spaced apart from the main body 210 and the cover 231 by a distance. Thus, when a user wants to receive a video signal through the antenna module 233 to view the digital television, the field pattern of the deployed antenna module 233 is not easily broken by the structure of the main body 210 and the cover 231 of the handheld electronic device 200. Moreover, the user can utilize the deployed antenna module 233 to support the handheld electronic device 200 without having to hold the handheld electronic device 200 by itself. The handheld electronic device 200 of the present embodiment will be further described below. As shown in FIGS. 1A and 1B, the cover 231 has a plurality of side edges, and the side edges are connected to each other. The antenna module 233 is detachably framed to the cover 231, for example, along the extending direction D of one of the long sides 231 s of the side. In this manner, the antenna module 233 can be rotated relative to the long side 231s of the cover 231 to expand, so that the display elements (not shown) of the handheld electronic device 200 can be correspondingly displayed in a landscape orientation to be close to the user's needs. In addition, when the antenna module 233 is subjected to a collision, the antenna module 233 can be detached from the cover body 231 by detachable characteristics to reduce the probability of damage. Please refer to FIG. 2A and FIG. 2B at the same time, FIG. 2A is a partial enlarged view of the handheld electronic device in FIG. 1A, and FIG. 2B is taken along a section line 2B-2B in FIG. 1A of 7 M342006.
