Abstract
An electronic device includes a first electric element a second electric element, and a circuit board. The circuit board is configured to deliver a signal between the first electric element and the second electric element. The circuit board includes a first portion, a second portion, and a third portion. The second and third portions extend from the first portion with the first portion therebetween. The circuit board also includes at least one signal line extending from the second portion to the third portion, a plurality of ground patterns extending from the second portion to the third portion, a plurality of first conductive vias positioned at the second portion and electrically connecting the plurality of ground patterns, and a plurality of second conductive vias positioned at the third portion and electrically connecting the plurality of ground patterns. The plurality of ground patterns include a meander form at the first portion.
