A multiband antenna is positioned on a substrate and includes a feeding portion, a grounding portion, and a radiating portion. The feeding portion is configured for feeding electromagnetic signals. The grounding portion is positioned on the substrate. The radiating portion electrically connects to the feeding portion for transceiving the electromagnetic signals. The radiation portion includes a first radiator and a second radiator. The first radiator includes a first radiating section that electrically connects to the feeding portion, a second radiating section, and a third radiating section, all of which electrically connects one another one-by-one in sequence and cooperatively defines a receiving space. The second radiator is housed in the receiving space and electrically connects to the feeding portion.
