Electronic device and antenna device for electronic device

The invention provides an electronic device and an antenna device for the electronic device. The antenna comprises a first conductor, a second conductor, a third conductor and a fourth conductor, wherein the first conductor and the second conductor are isolated from each other; the third conductor is fixed on the second conductor and is isolated from the second conductor; the fourth conductor is respectively coupled with the first conductor and the second conductor; the positions of the first conductor, on the two sides of the fourth conductor, are respectively connected with feeding points through the high-frequency conducting low-frequency isolating first decoupling elements; the two ends of the first conductor are respectively connected with the third conductor through the high-frequency conducting low-frequency isolating second decoupling elements. In the embodiment, the first antenna is arranged without cutting off or slotting a first conductor area in the antenna device, the clearance areas of the secon
