Circuit board and electronic device comprising same

An electronic device comprising:

• a housing comprising a first housing part and a second housing part configured to be movable relative to the first housing part;
• and
• a circuit board which is positioned in the housing and comprises a first portion bent in response to a movement of the second housing part, and a second portion which extends from the first portion and is more rigid than the first portion,
• wherein the circuit board comprises:
• a flexible dielectric extending from the first portion to the second portion,
• a first ground pattern extending from the first portion to the second portion and disposed on the flexible dielectric,
• a second ground pattern positioned in the second portion,
• a coverlay extending from the first portion to the second portion and comprising an electromagnetic shielding layer, a portion of the coverlay positioned between the first ground pattern and the second ground pattern at the second portion, and
• a first conductive via positioned in the second portion and configured to electrically connect to the first ground pattern, the second ground pattern, and the coverlay,
• a first signal line pattern extending from the first portion to the second portion, disposed on the flexible dielectric,
• a second signal line pattern positioned in the second portion, and
• a second conductive via positioned in the second portion and configured to electrically connect to the first signal line pattern and the second signal line pattern,
• wherein the second conductive via is configured to penetrate the coverlay and to be electrically isolated from the electromagnetic shielding layer of the coverlay.
