Summary:The utility model belongs to the technical field of dipole antennas, and provides a planar dipole dual-band antenna and an antenna device, which comprise a first radiation section, a signal feed-in point, a common ground, a second radiation section, an impedance matching section, a first signal transmission section and a second signal transmission section, the impedance matching section is horizontally arranged and configured to provide common impedance matching of the two frequency bands for the first radiation section and the second radiation section, and the length of the impedance matchingsection corresponds to a preset proportion value of the wavelength of the working frequency of the second radiation section and also corresponds to a preset proportion value of the wavelength of theworking frequency of the first radiation section. Therefore, the dual-frequency impedance matching function is realized by adopting the impedance matching section; and the frequency of the first radiation section is different
