The invention belongs to the technical field of dipole antennas, and provides a plane dipole dual-band antenna and an antenna device; the plane dipole dual-band antenna comprises a first radiation section, a signal feed-in point and a common ground, and further comprises a second radiation section, an impedance matching section, a first signal transmission section and a second signal transmissionsection; and the impedance matching section is horizontally arranged and is configured to provide common impedance matching of two frequency bands for the first radiation section and the second radiation section, wherein the length of the impedance matching section 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 the working frequency of the first radiation section. By adopting the impedance matching section, the function of double-band impedance matching is realized, and the frequency of the first radiation section is different from that of the second radiation section so that the antenna can be subjected to earth current coupling elimination in two frequency ranges, the stability of the radiation field of the antenna is ensured, and the residual earth current interference risk of a signal connection cable during connection is eliminated.
