Mobile communication device

摘要

A mobile communication device includes a substrate, a frame, a ground plane, and an antenna element. The substrate includes a first surface and a side wall. The frame includes a frame portion adjacent to the side wall. The ground plane is arranged on the first surface and includes a notch. An opening of the notch faces the frame portion. The antenna element includes a first radiation portion having a feeding point, a second radiation portion electrically connected to the ground plane, a third radiation portion electrically connected to the first radiation portion, and a fourth radiation portion electrically connected to the second radiation portion. Orthogonal projections of the first and second radiation portions on the first surface are located in the notch of the ground plane, and the third and fourth radiation portions are located on the frame portion or the side wall of the substrate.
