An apparatus including: a first housing and a second housing joined at a joint that is configured to enable relative rotational movement of the first housing and the second housing. The first housing includes a first grounded portion and a first coupling element. The second housing includes a second grounded portion and a second coupling element. The apparatus has a first configuration in which the first housing and the second housing have been rotated to a first relative orientation at which the first coupling element and the second coupling element are aligned and a radio frequency current path is formed between the first grounded portion and the second grounded portion via the first coupling element and the second coupling element. The apparatus has a second configuration in which the first housing and the second housing have been rotated to a second relative orientation at which the first coupling element and the second coupling element are not aligned and the radio frequency current path is not formed between the first grounded portion and the second grounded portion via the first coupling element and the second coupling element. |
