In other embodiments, the electronic device 100 may also be a tablet computer, and the type of electronic device 100 is not limited thereto.

[0075] Please refer to Figure 2 and Figure 3 The electronic device 100 in this embodiment includes a first housing 110, a second housing 120, and an antenna module 130. Specifically, the first housing 110 is a keyboard bezel (also known as a C-piece), and the second housing 120 is a bottom housing (also known as a D-piece). The first body 10 is assembled from the first housing 110 and the second housing 120. The antenna module 130 is disposed on the first body 10, but the present invention is not limited thereto.
