Abstract: The disclosure provides a multi-feed antenna including a first conductor layer, a second conductor layer, four supporting conductor structures and four feeding conductor lines. The second conductor layer has a first center position and is spaced apart from the first conductor layer at a first interval. The four supporting conductor structures respectively electrically connect the first conductor layer and the second conductor layer and form four electrically connected sections at the second conductor layer. The four electrically connected sections respectively extend from different side edges of the second conductor layer toward the first center position, so that the second conductor layer forms four mutually connected radiating conductor plates. The four feeding conductor lines are all located between the first conductor layer and the second conductor layer. The four feeding conductor lines and the four supporting conductor structures form an interleaved annular arrangement. Each of the feeding conductor lines has one end electrically connected to a coupling conductor plate. Each of the coupling conductor plates is spaced apart from a different one of the radiating conductor plates at a coupling interval. Each of the feeding conductor lines has another end electrically connected to a signal source respectively. The four feeding conductor lines excite the second conductor layer to generate at least four resonant modes. The at least four resonant modes cover at least one identical first communication band.

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.

The first conductor patch has a first coupling edge and a first connecting edge. The first connecting edge electrically connects with the first conductor layer through a first shorting structure. The second conductor patch has a second coupling edge and a second connecting edge. The second connecting edge electrically connects with the first conductor layer through a second shorting structure. The second coupling edge is spaced apart from the first coupling edge at a third interval forming a resonant open slot. The feeding conductor structure is located within the resonant open slot and has a first conductor line, a second conductor line and a third conductor line. The first conductor line is spaced apart from the first coupling edge with a first coupling interval. The second conductor line is spaced apart from the second coupling edge with a second coupling interval. The third conductor line electrically connects the first conductor line and the second conductor line. The signal source is electrically coupled to the feeding conductor structure. The signal source excites the integrated wideband antenna to generate one multi-resonance mode covering at least one first communication band.
