In this case, the third RFIC 226 is provided on a part (eg, bottom surface) of the second substrate (eg, sub PCB) separate from the first substrate, and the antenna 248 is placed on another part (eg, top surface). is disposed, the third antenna module 246 may be formed. According to one embodiment, antenna 248 may include an antenna array that may be used for beamforming, for example. By arranging the third RFIC 226 and the antenna 248 on the same substrate, it is possible to reduce the length of the transmission line therebetween. This, for example, can reduce loss (eg, attenuation) of a signal of a high frequency band (eg, about 6 GHz to about 60 GHz) used in 5G network communication by a transmission line. As a result, the electronic device 101 can improve the quality or speed of communication with the second cellular network 294 (eg, 5G network).

The second cellular network 294 (eg, 5G network) may be operated independently (eg, Stand-Alone (SA)) or connected to the first cellular network 292 (eg, a legacy network) ( Example: Non-Stand Alone (NSA)). For example, a 5G network may include only an access network (eg, a 5G radio access network (RAN) or a next generation RAN (NG RAN)) and no core network (eg, a next generation core (NGC)). In this case, after accessing the access network of the 5G network, the electronic device 101 may access an external network (eg, the Internet) under the control of a core network (eg, evolved packed core (EPC)) of the legacy network.

FIG. 3 illustrates an operation for wireless communication connection between a base station 320 and an electronic device 101 in the second network 294 (eg, 5G network) of FIG. 2 using directional beams for wireless connection. shows an embodiment of First, the base station (gNodeB (gNB), transmission reception point (TRP) 320 may perform a beam detection operation with the electronic device 101 for the wireless communication connection. In the illustrated embodiment, for beam detection, the base station 320 sequentially transmits a plurality of transmission beams, for example, first to fifth transmission beams 331-1 to 331-5 having different directions. By doing so, at least one transmission beam sweeping 330 can be performed.

The first to fifth transmission beams 331-1 to 331-5 may include at least one synchronization sequences (SS)/physical broadcast channel (PBCH) block (SS/PBCH BLOCK). The SS/PBCH block may be used to periodically measure the channel or beam intensity of the electronic device 101.

The electronic device 101 may measure a channel and beam intensity using the CSI-RS.

The transmission beams may form a radiation pattern having a selected beam width. For example, the transmission beams may have a broad radiation pattern having a first beam width or a sharp radiation pattern having a second beam width narrower than the first beam width. For example, transmission beams including SS/PBCH blocks may have a wider radiation pattern than transmission beams including CSI-RS.

The electronic device 101 may perform reception beam sweeping 340 while the base station 320 performs transmission beam sweeping 330 . For example, while the base station 320 performs the first transmission beam sweeping 330, the electronic device 101 fixes the first reception beam 345-1 in a first direction to the first to fifth transmission beams. A signal of an SS/PBCH block transmitted through at least one of the transmission beams 331-1 to 331-5 may be received. While the base station 320 performs the second transmission beam sweeping 330, the electronic device 101 fixes the second reception beam 345-2 in the second direction to form the first to fifth transmission beams 331-2. 1 to 331-5) can receive signals of the SS/PBCH Block transmitted. In this way, the electronic device 101 determines a communicable reception beam (eg, the second reception beam 345-2) and a transmission beam (eg, the third reception beam) based on the result of the signal reception operation through the reception beam sweeping 340. The transmit beam 331-3) may be selected.

As described above, after communicable transmit/receive beams are determined, the base station 320 and the electronic device 101 transmit and/or receive basic information for cell configuration, and based on this, information for additional beam operation can be configured. For example, the beam operation information may include detailed information on configured beams, SS/PBCH Block, CSI-RS, or configuration information on additional reference signals.

In addition, the electronic device 101 may continuously monitor the channel and beam strength using at least one of an SS/PBCH block and a CSI-RS included in a transmission beam. The electronic device 101 may adaptively select a beam having good beam quality using the monitoring operation. Optionally, when the communication connection is disconnected due to movement of the electronic device 101 or interruption of a beam, the above beam sweeping operation may be re-performed to determine a communicable beam.

For example, the folding state is a fully folding state in which the first surface 911 substantially overlaps the second surface 921 by rotation provided through the folding housing 960 ( 950) and a plurality of subfolding states caused by the folding of the folding housing 960 that are distinct from the states 900 and 950. For example, the electronic device 101 displays a first display on the entire area of the second display area 932 by having the first surface 911 and the second surface 921 face each other by the folding housing 960 . A state 950 in which the entire area of the area 931 substantially completely overlaps may be provided. For example, the electronic device 101 may provide a state 950 in which the first direction 901 is substantially opposite to the second direction 902 . As another example, the state 950 may mean a state in which the flexible display 930 is covered within the user's field of view looking at the electronic device 101 . However, it is not limited thereto.

In one embodiment, the flexible display 930 may be bent by rotation provided through the folding housing 960 . For example, in the flexible display 930, unlike the first display area 931 and the second display area 932, the third display area 933 may be bent according to a folding operation. For example, the third display area 933 may be in a curved state to prevent breakage of the flexible display 930 in the fully folded state. In the fully folded state, unlike the third display area 933 being curved, the entirety of the first display area 931 may completely overlap the entirety of the second display area 932 .

Among the antennas, at least a portion of the first antenna may be exposed to the outside. For example, through the side surface 922 of the second housing 920 that is distinguished from the second surface 921 of the second housing 920 on which the flexible display 930 is disposed, the plurality of electronic devices 101 are displayed. At least a portion of the second antenna among the antennas may be exposed to the outside.

Similarly, side surface 922 of second housing 920 includes one or more conductive members (eg, conductive member 982 ) and one or more non-conductive members (eg, non-conductive members 984 and 986 ). can include Conductive members and non-conductive members may be alternately arranged on the side of the housing. As the conductive members and the non-conductive members are alternately disposed on the side surface of the housing, the conductive members may be spaced apart from each other on the side surface. Similarly, the non-conductive members may be spaced apart from each other on the side surfaces. Referring to FIG. 9B , non-conductive members 974 and 976 disposed on the side surface 912 may be spaced apart from each other by the conductive member 972 . For example, the non-conductive members 974 and 976 may be disposed at both ends of the conductive member 972 in the longitudinal direction, respectively. Similarly, a conductive member 982 disposed on side 922 may be electrically isolated from other conductive members disposed on side 922 by non-conductive members 984 and 986 .

In one embodiment, the conductive members 972 and 982 disposed on each of the first housing 910 and the second housing 920 may correspond to at least a portion of an antenna associated with transmission and/or reception of a wireless signal. .

For example, when one of the conductive members 972 and 982 is in physical contact with a user's body part (eg, hand) and the other is physically separated from the user, the contact of the body part A phase difference may occur. The phase difference may correspond to θ _coupling in Equations 3 to 11, for example. The electronic device 101 according to an embodiment may measure and/or compensate for a phase difference due to a change in a wireless communication environment of the electronic device 101 including the contact of the body part.
