     According to an embodiment, the first surface  110 A may be defined by a front plate  102  (e.g., a glass plate or a polymer plate including various coating layers), at least a portion of which is substantially transparent. The second surface  110 B may be defined by a substantially opaque rear plate  111 . The rear plate  111 , for example, may be formed of coated or colored glass, ceramics, a polymer, a metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two thereof. The side surface  110 C may be coupled to the front plate  102  and the rear plate  111 , and may be defined by a side bezel structure (or ‘a frame structure’)  118  including a metal and/or a polymer.

The inner wall  310  may include the resting region  311 , in which the heat dissipating member  220  of the antenna module  200  is disposed, and the first slit  314 - 1  and the second slit  314 - 2 . The first slit  314 - 1  and the second slit  314 - 2  may extend from ends of the antenna module  200  in directions that face the first inclined region  312 - 1  and the second inclined region  312 - 2 .

     In the illustrated embodiment, each of the slits  314 - 1  and  314 - 2  may include an opening that passes through the inner wall  310 , and an insulating material accommodated in an interior of the opening. In certain embodiments, the first slit  314 - 1  and the second slit  314 - 2  may be formed at locations that are spaced apart from opposite ends of the antenna module  200  by a specific distance. 
     In the illustrated embodiment, the antenna module  200  may be disposed such that the heat dissipating member  220  is supported by the inner wall  310  and the antenna substrate  210  faces the opened direction (e.g., an upper side in the drawing) of the recess  309 . The heat dissipating member  220  of the antenna module  200  may be disposed between the first slit  314 - 1  and the second slit  314 - 2  formed in the inner wall  310 . The first surface  211  of the antenna substrate  210  may include the radiation area  213 . The radiation area  213  may be formed by the conductive pattern formed in the interior of or on a surface of the antenna substrate  210 .

For example, the first distance d 1  and the second distance d 2  may be distances substantially corresponding to a half of a wavelength of an RF signal that is radiated by the antenna module  200 . 
     In the illustrated embodiment, the inclined regions  312 - 1  and  312 - 2  may be inclined to define specific angles θ 1  and θ 2  with the direction, which the inner wall  310  of the antenna substrate  210  faces. The angles θ 1  and θ 2  may be defined by angles between a normal vector of the inner wall  310  and the inclined region. Then, the specific angles θ 1  and θ 2  may be 0 degrees to 60 degrees. 
     In certain embodiments, the angles θ 1  and θ 2  of the inclined regions  312 - 1  and  312 - 2  and the distances d 1  and d 2  between the antenna module  200  and the inclined regions  312 - 1  and  312 - 2  may be related to the radiation coverage of the antenna module.

Then, the RF signal may be deteriorated by the reflection signal. Accordingly, the distances d 1  and d 2  and the angles θ 1  and θ 2  may be adjusted to reduce the reflection signal generated by the inclined regions  312 - 1  and  312 - 2  to improve the radiation coverage of the antenna module  200 .

     The certain embodiments of the disclosure and the terms used herein do not limit the technology described in the disclosure to specific forms, and should be construed to include various modifications, equivalents, and/or replacements of the embodiments. With regard to description of drawings, similar components may be marked by similar reference numerals. The terms of a singular form may include plural forms unless otherwise specified. In the disclosure disclosed herein, the expressions “A or B”, “at least one of A or/and B”, “A, B, or C”, or “at least one of A, B, or/and C”, and the like used herein may include any and all combinations of one or more of the associated listed items. The terms, such as “first”, “second”, and the like used herein may refer to various elements of certain embodiments of the disclosure, but do not limit the elements. For example, such terms are used only to distinguish an element from another element and do not limit the order and/or priority of the elements. If it is mentioned that an element (e.g., a first element) is (functionally or communicatively) “connected” to another element (e.g., a second element), the first element may be directly connected to the second element or may be connected to the second element through another element (e.g., a third element). 
     In the disclosure, the expression “configured to” may be interchangeably used with, for example, “suitable for”, “capable of”, “modified to”, “made to”, “able to”, or “designed to” according to a situation in a hardware or software way. In some situations, the expression “a device configured to” may mean that the device is “capable of” operating together with another device or other components. CPU, for example, a “processor configured to (or set to) perform A, B, and C” may mean a dedicated processor (e.g., an embedded processor) for performing a corresponding operation or a generic-purpose processor (e.g., a central processing unit (CPU) or an application processor) which may perform corresponding operations by executing one or more programs which are stored in a memory device. 
     The term “module” used in the disclosure may include a unit configured in a hardware, software, or firmware way, and for example, may be used interchangeably with the terms such as logic, a logic block, a component, or a circuit. The “module” may be an integral component, or a minimum unit or a part which performs one or more functions. The “module” may be implemented mechanically or electronically, and for example, may include an application-specific integrated circuit (ASIC) chip, field-programmable gate arrays (FPGSs), or a programmable logic device that is known or to be developed in the future, which performs some operations. 
     At least some of the devices (e.g., modules or functions) or methods (e.g., operations) according to certain embodiments of the disclosure may be implemented by an instruction stored in a computer-readable storage medium, for example, in the form of a program module. When the instruction is executed by the processor, the processor may perform a function corresponding to the instruction. The computer-readable recording medium may include a hard disk, a floppy disk, a magnetic medium (e.g., a magnetic tape), an optical recording medium (e.g., a CD-ROM or a DVD), an magneto-optical medium (e.g., a floptical disk), and an embedded memory. The instruction may include a code made by a compiler or a code that may be executed by an interpreter. 
     Each of the elements (e.g., a module or a program) according to certain embodiments may include a single or a plurality of entities, and some of the corresponding sub-elements may be omitted or another sub-element may be further included in certain embodiments. Alternatively or additionally, some elements (e.g., a module or a program module) may be integrated into one entity to perform functions performed by the corresponding elements before the integration in the same way or similarly. The operations performed by a module, a program module, or another element according to certain embodiments may be executed sequentially, in parallel, repeatedly, or heuristically, or at least some operations may be executed in another sequence or may be omitted, or another operation may be added.
