TECHNICAL FIELD

The disclosure relates to an antenna structure including an interposer and an electronic device including the same. More particularly, the disclosure relates to an electronic device including a flexible display which secures a pattern antenna mounting space and reduce antenna performance degradation through an antenna structure using an interposer and a printed circuit board (PCB).

BACKGROUND ART

Electronic devices tend to have smaller sizes while having more diversified functions, and it has thus become important to secure spaces for arrangement of electronic components (for example, processors, communication circuits, or memories) for performing various functions of electronic devices.

In order to secure spaces in which electronic components can be arranged, an increasing number of electronic devices have recently used interposers to form a stacked structure of multiple PCBs. For example, an electronic device may have multiple stacked PCBs and may have an interposer which has at least one via for electrically connecting PCBs, and which is arranged between the stacked PCBs, thereby securing a space in which electronic components can be arranged.

In addition, in response to such demands for small sizes and multiple functions, electronic devices may adopt a flexible display such that the size of the flexible display, which is visually exposed, can be varied, thereby providing both large screens and portability. For example, an electronic device employing a flexible display may secure portability if the display is partially rolled into the electronic device and thus reduced, and may provide a large screen when the display is expanded.

DISCLOSURE OF INVENTION

An electronic device employing a flexible display may have a limited area in which an antenna using a conductive pattern, such as laser direct structuring (LDS), can be arranged, compared with an electronic device of the related art. For example, at least a part of the flexible display may be arranged in an area in which an antenna may be arranged, thereby reducing the area in which an antenna may be arranged.

In addition, in the case of a rollable or slidable electronic device, the antenna connecting structure may become longer, thereby increasing the line loss and degrading the antenna radiation performance.

The electronic device includes a housing including a first housing and a second housing coupled to the first housing to be movable with respect to the first housing, a flexible display coupled to the housing and having a display area shown to the outside of the electronic device and expanded or reduced in at least one direction according to a movement of the second housing, a PBA disposed in the housing, and a wireless communication circuit, wherein the PBA includes a first PCB, a second PCB disposed parallel to the first PCB, the second PCB including a conductive area, and an interposer surrounding a space between the first PCB and the second PCB, wherein the interposer includes a first partition wall structure configured to provide shielding for at least one electronic component disposed on the PBA and a second partition wall structure connected to the first partition wall structure and configured to include a dielectric material, the second partition wall structure including a conductive via configured to connect the first PCB and the second PCB, wherein the wireless communication circuit is configured to transmit or receive a signal in a specified frequency band by feeding power to the conductive area of the second PCB through the conductive via.
