Abstract: Embodiments of the present invention relate to the field of electronic communication, and more particularly, to a printed antenna and a terminal device comprising said printed antenna. Said printed antenna includes a printed circuit board and at least two antenna patterns; said printed circuit board includes at least two copper foil layers; said at least two antenna patterns are formed on different copper foil layers of said printed circuit board respectively, and said at least two antenna patterns are electrically connected to each other. Since said printed antenna includes a plurality of monolayer antenna patterns, said antenna has a stable performance index and less dependent on the parameters of said printed circuit board, such as the thickness, thereby greatly improving the performance and communication quality of the terminal device's antenna.
