Description

[Technical Field] Various embodiments of the disclosure disclose an electronic device including a conductive pattern and an adhesive member. [Background Art] The use of electronic devices such as bar-type, foldable-type, rollable-type, or sliding-type smartphones or tablet PCs is increasing, and various functions are being provided to the electronic devices. The electronic device may transmit and receive phone calls and various data with other electronic devices through wireless communication. The electronic devices may include at least one antenna (e.g., an antenna radiator) in order to perform wireless communication with another electronic device by using a network. [Disclosure of Invention] [Technical Problem] An electronic device may include a side surface member (e.g., a housing) including a support member, and a front surface plate may be disposed in a first direction (e.g., an upper portion) of the side surface member, and a rear surface plate may be disposed in a second direction (e.g., a lower portion) of the side surface member. For example, among components included in the electronic device, at least a portion of the components (e.g., the front surface plate) may be coupled to the side surface member in the first direction by inserting a screw into a fastening hole formed at a corner of the support member, or through a coupling hook. For example, the rear surface plate may be coupled to the side surface member in the second direction of through an adhesive member. In the electronic device, an adhesive member (e.g., a double-sided adhesive tape) and a conductive pattern (e.g., an antenna pattern) may be disposed between the fastening hole formed at the corner of the support member and a portion of the side surface member. When the adhesive member and the conductive pattern are disposed together between the fastening hole and the portion of the side surface member, an area of the adhesive member and an area of the conductive pattern may be limited. For example, when the area of an adhesive member disposed at a corner of the support member is limited, an adhesive force for bonding the side surface member and the rear surface plate may be weakened. For example, when an area of a conductive pattern disposed at a corner of the support member is limited, radiation performance of the conductive pattern operating as an antenna may be deteriorated. Various embodiments of the disclosure may provide an electronic device capable of expanding an area of an adhesive member and an area of a conductive pattern that are disposed between a side surface member including a support member and a rear surface plate. The technical problems to be addressed by this disclosure are not limited to those described above, and other technical problems not mentioned above may be clearly understood by a person ordinarily skilled in the related art to which the disclosure pertains. [Solution to Problem] According to an embodiment of the disclosure, an electronic device may include a housing including a front surface plate, a rear surface plate, and a side surface member forming an outer side wall of the electronic device. According to an embodiment, the electronic device may include a first support member that is integrally formed with the side surface member and includes a first surface and a second surface. According to an embodiment, the first support member may include a fastening hole formed in a corner region of the first support member and an opening formed adjacent to the fastening hole. According to an embodiment, the electronic device may include an adhesive member that is disposed in a first region of the second surface of the first support member and partially surrounds the fastening hole. According to an embodiment, the electronic device may include a conductive pattern that extends from the second surface of the first support member to the first surface of the first support member through the opening. According to an embodiment, a portion of the conductive pattern may be disposed in a second region of the second surface of the first support member so as to partially surround the fastening hole. According to an embodiment, the conductive pattern may be formed so as not to overlap with the adhesive member in the first region between the fastening hole and a corner of the side surface member. [Advantageous Effects of Invention] According to various embodiments of the disclosure, by extending areas of an adhesive member (e.g., a double-sided adhesive tape) and a conductive pattern (e.g., an antenna pattern) that are disposed between a side surface member including a support member and a rear surface plate, an adhesive force between the housing and the rear surface plate may be improved, and radiation performance of an antenna may be improved. In addition, various effects that are directly or indirectly understood through this document may be provided. [Brief Description of Drawings] In connection with the description of t
