The antenna unit includes a slot (110) defining on the metal shell, a coaxial cable (3) having an inner conductor (32) connected to a first side (111) of the slot and an outer braiding (33) connected to a second side (112) of the slot, and a fastening member (34) extending across the coaxial cable and securing the coaxial cable on the metal shell.

Abstract: An electronic device (100) includes a metal shell (1) having a number of walls (11,12) and an antenna unit (3). The metal wall has an interior space (17) defined therebetween, at least one recess (110) defined on one of the wall (11), and a mating member (111) disposed around the recess and extending into the interior space. The antenna unit is received in the recess and has a locating portion (36) extending from a side portion thereof and pivotably engaging with the mating member. When the antenna unit is rotated from a closed position to an opening position, another side portion of the antenna unit extends outward from the recess.
