Ultra wide band dipolar antenna

The utility model relates to a super wideband dipole antenna which comprises a dielectric substrate, two dipole arms and a supply lead. The two dipole arms are both rectangular thin sheet metals with completely same shape and size and are coated on the same surface of the dielectric substrate or are respectively coated on two surfaces of the dielectric substrate. The antenna is applicable to the super wideband wireless communication field; a wideband BW is more than 100 percent (VSWR is less than 1.5), and is larger than 7.5 GHz; the whole working frequency band has the omnidirectional radiation character. The super wideband dipole antenna has simple structure, consistent capability, can be printed and manufactured, and is suitable for mass production. The antenna is in a plane structure and is suitable for system integration.
