For example, a 5G network may have only an access network (e.g., 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, the electronic device 101 may access the access network of the 5G network and then access an external network (eg, the Internet) under the control of the core network (eg, evolved packed core (EPC)) of the legacy network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., New Radio (NR) protocol information) is stored in the memory 230 and stored in the memory 230, 120, first communication processor 212, or second communication processor 214).

Although not shown in FIG. 3, in a 5G system, a base station may be implemented in distributed deployment to support network function virtualization and more efficient resource management and scheduling. For example, in a 5G system, a base station (gNB) may be further divided into a central unit (CU) and a distributed unit (DU). The CU has at least Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP) protocol layers, and may also include Service Data Adaptation Protocol (SDAP).

The first antenna 410 may support at least one first LTE frequency band. The first antenna 410 may be connected to at least one filter (not shown) for the first LTE frequency band. At least one first LTE frequency band may include the frequency band of the LTE carrier of EN-DC. At least one first LTE frequency band may include a frequency band of a low-band LTE carrier.

The second antenna 420 may support at least one second LTE frequency band. At least one second LTE frequency band may be located in a higher frequency region than the at least one first LTE frequency band of the first antenna 410.

At least one first NR frequency band may include the frequency band of the NR carrier of EN-DC. At least one first NR frequency band may include a frequency band of a mid-band NR carrier (eg, NR Band 1 (N1), N2, N3, N66). According to one embodiment, the second antenna 420 may operate as an additional transmission antenna for additional feeding of the NR carrier signal (hereinafter, NR signal).

The third antenna 430 may support at least one second NR frequency band. The third antenna 430 may be connected to at least one filter (not shown) for the second NR frequency band. At least one second NR frequency band may include the frequency band of the NR carrier of EN-DC. At least one second NR frequency band may include a frequency band for high-band NR (eg, N77, N78, N79). According to one embodiment, the third antenna 430 may operate as an additional transmission antenna for additional feeding of NR signals.

The NR transmit/receive antenna 450 may support at least one first NR frequency band and at least one second NR frequency band. At least one first NR frequency band may include a frequency band for mid-band NR (e.g., NR Band 1 (N1), N2, N3, N66).

The electronic device can determine the frequency band of the NR carrier, that is, the NR frequency band, and determine an antenna for NR transmission and reception that supports the NR frequency band.

When the second antenna 420 is used for transmission of an NR signal, a signal of an LTE carrier (hereinafter referred to as an LTE signal) may be transmitted through the first antenna 410. In the case of MB-MB EN-DC using a mid-band LTE carrier and a mid-band NR carrier, the LTE carrier and NR carrier, which are anchor carriers, may correspond to the same frequency band. Since it is difficult to secure isolation between the first antenna 410 and the second antenna 420 in the same frequency band, interference may occur between two relatively adjacent antennas. Interference can cause degradation of antenna performance. When the second antenna 420 is used for transmission of an NR signal, the LTE signal may be transmitted through the first antenna 410. In the case of HB-HB EN-DC using a high-band LTE carrier and a high-band NR carrier, the LTE carrier and the NR carrier, which are anchor carriers, may correspond to the same frequency band.

Meanwhile, the location of the NR transmit/receive antenna 450 may affect other functions in addition to the radiation performance of the electronic device 101. For example, the NR transmit/receive antenna 450 may be located closer to the camera than the first antenna 410, the second antenna 420, and the third antenna 430. Noise may occur in the camera due to the NR signal radiated through the NR transmit/receive antenna 450. In addition, to ensure isolation between antennas located at the top (e.g., NR transmit/receive antenna 450 or receive antennas (not shown)), the metal bridge of the electronic device 101 uses power back according to the grip sensor. Power-back off can be disabled. As power backoff is not applied to the NR transmit/receive antenna 450, specific absorption rate (SAR) may increase.

Embodiments of the present disclosure may additionally use other antennas for transmission of NR signals in order to maintain or increase radiation performance and reduce camera noise and SAR caused by the NR transmit/receive antenna 450.

Referring to FIG. 6 , the electronic device 101 may include a first antenna 610, a second antenna 620, a third antenna 630, and an NR transmit/receive antenna 650.

The NR transmit/receive antenna 650 can be used for transmission of NR signals. The NR transmit/receive antenna 650 may be connected to the first communication module 601. According to one embodiment, the first communication module 601 may be an EN-DC transmission module. The first communication module 601 may include filters for NR frequency bands for EN-DC. The first communication module 601 may support at least one first NR frequency band and at least one second NR frequency band. At least one first NR frequency band may include a frequency band for mid-band NR (eg, NR Band 3 (N3)). At least one second frequency band may include a frequency band for high-band NR (eg, N77, N78, N79).

The first antenna 610 may be used for transmission of LTE signals. The first antenna 610 may be connected to the second communication module 603. According to one embodiment, the second communication module 603 may be a front end module (FEM) for LTE. The second communication module 603 may support at least one first LTE frequency band. At least one first LTE frequency band may include a frequency band of a mid-band LTE carrier (e.g., Band 1 (B1) band, B2 band, B3 band, B4 band, B66 band).

The second antenna 620 can be used for transmitting and receiving LTE signals. The second antenna 620 may be connected to the second communication module 603. According to one embodiment, the second communication module 603 may be a front-end module for LTE. The front-end module may support at least one second LTE frequency band. At least one second LTE frequency band may include a frequency band of a high-band LTE carrier (e.g., B7 band, Band 38 band, B41 band). According to one embodiment, the second antenna 620 may be used for transmission of an NR signal. The second communication module 603 may support at least one first NR frequency band. At least one first NR frequency band may include a frequency band of a mid-band NR carrier (eg, N1 band, N2 band, N3 band, N66 band). The electronic device 101 may transmit a signal of a mid-band NR carrier (eg, NR Band 3 (N3)) through the second communication module 603 and the second antenna 620.

The third antenna 630 can be used for transmitting and receiving NR signals. The third antenna 630 may be connected to the third communication module 605. According to one embodiment, the third communication module 605 may be a communication module for receiving an NR signal. The third communication module 605 may support at least one second NR frequency band. At least one second NR frequency band may include a frequency band for high-band NR (eg, N77, N78, N79). According to one embodiment, the third antenna 630 may be used for transmission of NR signals. The electronic device may transmit a signal of a high-band NR carrier (eg, NR Bands 77, 78, and 79) through the third communication module 605 and the third antenna 630.

According to one embodiment, the first communication module 601 may include a first switch 611 inside the first communication module 601. The electronic device may feed a signal of the NR carrier to both the NR transmit/receive antenna 650 and additional antennas (e.g., the second antenna 620 and/or the third antenna 630) through the first switch 611. . According to one embodiment, the distance between the additional antenna and the camera 640 may be greater than the distance between the NR transmit/receive antenna 650 and the camera 640. In order to simultaneously feed signals to the NR transmit/receive antenna 650 and the additional antenna, paths may be branched through the first switch 611. Power output from the power amplifier (PA) of the first communication module 601 may be distributed to the NR transmit/receive antenna 650 and additional antennas by the first switch 611. The first switch 611 may function as a power divider. For example, assume that the power amplifier (PA) of the first communication module 601 outputs power of 24 dBm. The power distributed through the first switch 611 is lowered by 3 dBm, so that 21 dBm of power can be transmitted to each of the NR transmitting and receiving antennas 650 and the additional antenna. That is, the PA of the first communication module 601 outputs power of 24 dBm, but the power delivered to each of the NR transmit/receive antenna 650 and the additional antenna may be 21 dBm. Due to power distribution, the influence of the NR transmit/receive antenna 650 relatively adjacent to the camera 640 may be reduced. As the power allocated to the NR transmit/receive antenna 650 is lowered, noise of the camera 640 may be reduced and SAR may also be reduced. Performance degradation due to the reduced power of the NR transmit/receive antenna 650 can be compensated for by radiation from the additional antenna.

According to one embodiment, it may be required that the additional antenna is not an anchor antenna, but rather an antenna that is not used for NR reception.
