Abstract: An ultra-wideband antenna device is disposed on a casing of an electronic device. The ultra-wideband antenna device includes radio frequency terminals, a first antenna module, a second antenna module, and a switch module. The radio frequency terminals, the first antenna module and the switch module are located in the casing. The first antenna module is located on a metal frame of the casing, and the first antenna module includes a first antenna. The second antenna module includes a second antenna, a third antenna, and a fourth antenna. The switch module is connected between the radio frequency terminals and the first antenna module. When the switch module turns on one of the radio frequency terminals and the first antenna for distance measurement, the switch module selectively turns on at least one of the second antenna, the third antenna, or the fourth antenna.
