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.
