Abstract
The disclosure provides a communication device. The communication device includes a ground conductor portion and a multi-antenna system. The multi-antenna system includes at least a first and a second resonant portion, each of which is disposed on the corresponding radiating edge of the ground conductor portion. Each of the resonant portions may have a loop resonant structure or may have an open-slot resonant structure, and has a resonant path. The electrically coupling portion makes the length of the resonant path less than or equal to 0.18 times the wavelength of the lowest operating frequency of the multi-antenna system, and thereby excites the corresponding radiating edge and forms a strong surface current distribution, and generates an effective radiating energy and at least one resonant mode, in which the effective radiating energy has a corresponding strongest radiation direction.
