Abstract
An antenna and a communication device. The antenna provided includes a dielectric substrate, a folded dipole, and N symmetrical dipoles. A combined line is disposed on the dielectric substrate, and the combined line has a first end and a second end. The folded dipole is located at the first end of the combined line and is connected to the combined line. The N symmetrical dipoles are disposed on the dielectric substrate, and the N symmetrical dipoles are connected to the combined line. The N symmetrical dipoles are sequentially arranged from the first end to the second end of the combined line.
