[0023] Such as figure 1 As shown, the embodiment of the present invention provides an antenna device, which is applied to an electronic device. The electronic device includes a metal battery cover 1 and a plastic support structure 2. The antenna device specifically includes: a slot antenna body 3, a first tuner part 4, the second tuning part 5 and the feeding part 6.
[0024] Wherein, the metal battery cover 1 has a slit structure, and the plastic support structure 2 is located in the slit structure, which not only shields the slit structure from being exposed to the outside of the metal battery cover 1, but also makes the metal battery cover 1 as a whole flat or curved surface. , without bumps and depressions on the surface. Further, the slot antenna body 3 of the antenna device is formed along the first edge where the metal battery cover 1 is in contact with the top surface of the plastic support structure 2, and a connecting portion 31 is provided on the metal battery cove...
