Dipole antenna

A dipole antenna includes a radiating portion having a feeding point, a grounding portion and a coaxial cable. Said grounding portion is electrical isolation with the feeding point. Said coaxial cable includes an inner conductor connected with the feeding point and a metal braid layer connected with the grounding portion. The dipole antenna includes a pair of long sides and a pair of short sides connected with the long sides. The radiating portion includes a first part disposed adjacent to the ground portion and a pair of slots extending from a middle region of the first part to the long sides, respectively. The remaining part of the radiating portion is divided into a second part extending from the middle region of the first part and a third part extending from the both sides of the first part, respectively. According to the usage need of electronic equipment for increasing the bandwidth and improving the radiation capacity of the antenna.
