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.

Abstract:
An electronic device according to an example embodiment includes a printed circuit board (PCB) configured to connect a first electronic component and a second electronic component and block power noise in a target frequency band. The PCB may include a first signal layer including a first signal plate having a length pattern with a length corresponding to a first parameter of the target frequency band, a first ground layer including a first ground plate with a first area, a second signal layer including a second signal plate, a first dielectric having a first thickness and a first permittivity, a second ground layer including a second ground plate with a second area corresponding to a second parameter of the target frequency band, and a second dielectric having a second thickness and a second permittivity corresponding to the second parameter.
Abstract:
A method and an apparatus for measuring performance of an electronic device are provided. The apparatus includes an electromagnetic wave measuring device for measuring an actual level of an electromagnetic wave of an electronic device, and an analysis controller for applying a previously stored level change value to the actual level of the electromagnetic wave to compute a measured level of the electromagnetic wave. The method and the apparatus for measuring performance of an electronic device can easily measure an electromagnetic wave level of the electronic device without using a device suggested by an international standard.
