This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2018-0126469, filed on Oct. 23, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.
The disclosure relates to an electronic device including a ground layer of a Flexible Printed Circuit Board (FPCB) and a conductive structure which electrically couples a ground layer of a Printed Circuit Board (PCB).
With the development of digital technologies, electronic devices are provided in various forms, such as a smart phone, a tablet Personal Computer (PC), a Personal Digital Assistant (PDA), or the like. The electronic device is also developed such that it is worn by a user to improve portability and user accessibility. With the development of wireless communication technologies, electronic devices (e.g., communication electronic devices) are widely used in everyday life, and thus the use of content increases exponentially. The electronic device may include a member such as a Flexible Printed Circuit Board (FPCB) which provide electrical coupling between elements regarding a wireless communication circuit.
When electromagnetic noise (e.g., electromagnetic wave noise) generated inside an electronic device has effect on a corresponding transmission line (e.g., an FPCB), performance deterioration may occur. For example, wireless communication of a high frequency band may be more sensitive to an influence of the electromagnetic noise of a high frequency band.
Embodiments of the disclosure may provide an electronic device including a ground layer of an FPCB and a conductive structure which electrically couples a ground layer of a PCB, to reduce Electro Magnetic Interference (EMI) on the FPCB utilized as a transmission line.
According to an example embodiment, an electronic device may include a housing including a first plate, a second plate facing away from the first plate, and a side housing surrounding a space between the first plate and the second plate and joined to the second plate or constructed integrally with the second plate, a display viewable through at least part of the first plate, a first Printed Circuit Board (PCB) disposed between the first plate and the second plate and including at least one first ground layer, a Flexible Printed Circuit Board (FPCB) at least partially overlapping the first PCB when viewed from above the first plate, the FPCB including a first end electrically coupled to the first PCB, a second end, and at least one second ground layer, and a conductive structure comprising a conductive material disposed between the first PCB and the FPCB and electrically coupling the first ground layer and the second ground layer.
According to various embodiments, since a conductive structure disposed between a Flexible Printed Circuit Board (FPCB) and a Printed Circuit Board (PCB) electrically couples a ground layer of the FPCB and a ground layer of the PCB, Electro Magnetic Interference (EMI) on the FPCB is decreased, thereby improving performance thereof. In addition, the conductive structure may be utilized as a support which props the FPCB, thereby providing a robust structure between the FPCB and the PCB.
