The second REIC 224 may convert the pre-processed 5G Sub6 RE signal into a baseband signal so as to be processed by a corresponding communication processor of the first communication processor 212 or the second communication processor 214.

The third RFIC 226 may convert a baseband signal generated by the second communication processor 214 into an RE signal (hereinafter referred to as a “5G Above6 RF signal”) in a 5G Above6 band (e.g., approximately 6 GHz to approximately 60 GHz) to be used in the second network 294 (e.g., a 5G network). In the case of receiving a signal, a 5G Above6 RE signal may be obtained from the second network 294 (e.g., a 5G network) through an antenna (e.g., the antenna 248) and may be pre-processed through a third RFFE 236. The third RFIC 226 may convert the pre-processed 5G Above6 RE signal into a baseband signal so as to be processed by the second. communication processor 214. According to an embodiment, the third RFFE 236 may be implemented as a part of the third RFIC 226.

According to an embodiment, the electronic device 101 may include the fourth RFIC 228 independently of the third RFIC 226 or as at least a part of the third MC 226. In this case, the fourth RFIC 228 may convert a baseband signal generated by the second communication processor 214 into an RF signal (hereinafter referred to as an “IF signal”) in an intermediate frequency band (e.g., approximately 9 GHz to approximately 11 GHz) and may provide the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal into a SG Above6 RF signal. In the case of receiving a signal, a 5G Above6 RF signal may be received from the second network 294 (e.g., a 5G network) through an antenna (e.g., the third antenna 248) and may be converted into an IF signal by the third RFIC 226. The fourth RFIC 228 may convert the IF signal into a baseband signal so as to be processed by the second communication processor 214.

According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as a part of a single package or a single chip.

According to an embodiment, the first RFIC 232 and the second RFFE 234 may be implemented as a part of a single package or a single chip. According to an embodiment, at least one of the first antenna module 242 or the second antenna module 244 may be omitted or may be combined with any other antenna module to process RF signals in a plurality of bands corresponding thereto.

According to an embodiment, the third RFIC 226 and the antenna 248 may be disposed at the same substrate to form a third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be disposed on a first substrate (e.g., a main PCB). In this case, the third RFIC 226 may be disposed in a partial region (e.g., on a lower surface) of a second substrate (e.g., a sub PCB) independent of the first substrate, and the antenna 248 may be disposed in another partial region (e.g., on an upper surface) of the second substrate. As such, the third antenna module 246 may be formed. According to an embodiment, the antenna 248 may include, for example, an antenna array to be used for beamforming. As the third RFIC 226 and the antenna 248 are disposed at the same substrate, it may be possible to decrease a length of a transmission line between the third MC 226 and the antenna. 248. For example, the decrease in the transmission line may make it possible to prevent a signal in a high-frequency band (e.g., approximately 6 GHz to approximately 60 GHz) used for 5G network communication from being lost (or attenuated) due to the transmission line. As such, the electronic device 101 may improve the quality or speed of communication with the second network 294 (e.g., a 5G network).

The second network 294 (e.g., a 5G network) may be used independently of the first network 292 (e.g., a legacy network) (e.g., this scheme being called “stand-alone (SA)”) or may be used in connection with the first network 292 (e.g., this scheme being called “non-stand alone (NSA)”).

For example, only an access network (e.g., a 5G radio access network (RAN) or a next generation RAN (NG RAN)) may be present in the 5G network, and a core network (e.g., a next generation core (NGC)) may be absent from the 5G network. In this case, the electronic device 101 may access the access network of the 5G network and may then access an external network (e.g., an Internet) under control of a core network (e.g., an evolved packed core (EPC)) of the legacy network. Protocol information (e.g., LTE protocol information) for communication with the legacy network or protocol information (e.g., New Radio (NR) protocol information) for communication with the 5G network may be stored in the memory 130 so as to be accessed by any other component (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).

In an embodiment, the ninth to twelfth paths 532, 534, 536, and 538 may be extended from the one ends of the first to fourth paths 542, 544546, and 548. The ninth to twelfth paths 532, 534. 536, and 538 may be extended to be spaced from the fifth to eighth paths 522, 524, 526, and 528. The ninth to twelfth paths 532, 534, 536, and 538 may be disposed to face the plurality of through-holes 512, 514, 516, and 518. For example, the ninth to twelfth paths 532, 534, 536, and 538 may be disposed to extend across the plurality of through-holes 512, 514, 516, and 518 in the second direction. The number of ninth to twelfth paths 532, 534, 536, and 538 thus disposed may be equal to the number of through-holes 512, 514, 516, and 518.

In an embodiment, when viewed in the Z-axis direction, portions of the ninth to twelfth paths 532, 534, 536, and 538 may overlap the plurality of through-holes 512, 514, 516, and 518. The ninth to twelfth paths 532, 534, 536, and 538 may be disposed to be spaced from the plurality of through-holes 512, 514, 516, and 518 in the Z-axis direction.

In an embodiment, the first to fourth paths 542, 544, 546, and 548 may be disposed to be spaced from the plurality of through-holes 512, 514, 516, and 518. The fifth to eighth paths 522, 524, 526, and 528 and the ninth to twelfth paths 532, 534, 536, and 538 may be branched and disposed from the first to fourth paths 542, 544, 546, and 548. The fifth path 522 and the ninth path 532 branched from the first path 542 may be formed to overlap the first through-hole 512.

In an embodiment, the connection parts 552, 554, 556, and 558 may be formed at the first to fourth paths 542, 544, 546, and 548. The connection parts 552, 554, 556, and 558 may be portions that are connected with the first to fourth paths 542, 544, 546, and 548 and have a thickness thinner than that of the first to fourth paths 542, 544, 546, and 548. The connection parts 552, 554, 556, and 558 of the first to fourth paths 542, 544, 546, and 548 may be connected with the MC 560 being a wireless communication circuit. For example, as illustrated in FIG. 5C, the connection parts 552, 554, 556, and 558 of the first to fourth paths 542, 544, 546, and 548 may be connected with the

MC 560 through the transmission line 570 or a via. The connection parts 552, 554, 556, and 558 of the first to fourth paths 542, 544, 546, and 548 may be fed (or may be supplied with a power) from the RFIC 560. The connection parts 552, 554, 556, and 558 of the first to fourth paths 542, 544, 546, and 548 may be connected with the RFIC 560 through the transmission line 570 to transmit and/or receive an mmWave signal. The transmission line 570 may independently connect the connection parts 552, 554, and 558 with the RFIC 560. The transmission line 570 may be implemented at the substrate 550.

In an embodiment, the substrate 550 may include the first to twelfth paths 522, 524, 526, 528, 532, 534, 536, 538, 542, 544, 546, and 548. A non-conductive layer may be disposed between the plurality of through-holes 512, 514, 516, and 518 included in the first portion 510 and the first to twelfth paths 522, 524, 526, 528, 532, 534, 536, 538, 542, 544, 546, and 548. The non-conductive layer included in the substrate 550 may prevent the plurality of through-holes 512, 514, 516, and 518 included in the first portion 510 and the first to twelfth paths 522, 524, 526, 528, 532, 534, 536, 538, 542, 544, 546, and 548 from being short-circuited.

In an embodiment, the fifth path 522 and the ninth path 532 branched from the first path 542 may feed a signal of the same frequency and the same phase to the first through-hole 512 overlapping the fifth path 522 and the ninth path 532. The first through-hole 512 may radiate a fed signal. As such, the structure 500 may transmit and/or receive an RF signal by using the first to fourth through-holes 512, 514, 516, and 518,

FIG. 6 is a view 600 illustrating the first portion 510, a through-hole 610, a first path 640, a second path 620, and a third path 630, according to an embodiment.

In an embodiment, the through-hole 610 (e.g., the first through-hole 512 of FIG. 5A) may penetrate the first portion 510 that is a portion of a side member and is formed of a conductive material. For example, the through-hole 610 may penetrate the first portion 510 in the Z-axis direction. The through-hole 610 may have a slot structure. The electronic device 101 may transmit and/or receive an RF signal of a specified frequency through the through-hole 610. A metal region including the through-hole 610 may be a radiator that radiates the RF signal of the specified frequency. The electronic device 101 may radiate an RF signal through the through-hole 610 or a slot. As such, in a structure including the through-hole 610, a part of the first portion 510, in which a slot is formed at a conductive material and the slot is filled with a nonmetal material, may function as a radiator of the electronic device 101.

In an embodiment, the first path 640 may be disposed to face the through hole 610. One side of the first path 640 (e.g., one side of the first path 542 of FIG. 5A) may diverge to the second path 620 (e.g., the fifth path 522 of FIG. 5A) and the third path 630 (e.g., the ninth path 532 of FIG. 5A). An opposite end of the first path 640 may be connected with a wireless communication circuit (e.g., the RFIC 560 of FIG. 5B).

In an embodiment, the first path 640 may include a connection part 650. The connection part 650 may be connected with a port of a wireless communication circuit (e.g., the RFIC 560 of FIG. 5C), may be supplied with a signal, and may feed the signal to the through-hole 610. To feed a signal, the connection part 650 of the first path 640 may be implemented with a transmission line of a microstrip or strip form. The connection part 650 of the first path 640 may be connected with an RFIC (e.g., the RFIC 560 of FIG. 5C) through the transmission line (e.g., the transmission line 570 of FIG. 5C) and may transmit and/or receive a signal.

In an embodiment, the second path 620 and the third path 630 may be disposed to pass above the through-hole 610. The second path 620 and the third path 630 may be implemented with two transmission lines that are disposed just above the through-hole 610 or the slot. Each of the second path 620 and the third path 630 may be designed to have a characteristic impedance of about 50 Ω. In an embodiment, an open stub 621 and/or 631 that is different in width from the second path 620 and the third path 630 may be connected with the second path 620 and/or the third path 630. The open stubs 621 and 631 may match an input impedance of the through-hole 610 and the second path 620 and the third path 630.

In an embodiment, the second path 620 and the third path 630 may be coupled with the first path 640 on one side thereof. The first path 640 that is integrated to one line may be connected with a port of a wireless communication circuit. For example, the first path 640 may be connected with a port of a wireless communication circuit (e.g., the RFIC 560 of FIG. 5B).

In an embodiment, because the first path 640 has a greater width than a transmission line of 50 Ω, the first path 640 may have a characteristic impedance of about 35 Ω. For example, the first path 640 may function as a 3 dB T-junction combining a 3 dB power. The first path 640 may function as an impedance transformer that transforms an impedance from about 50 Ω to about 35 Ω.

In an embodiment, a slit 660 of a triangle form may be disposed at a junction of a transmission line at which the first path 640 is coupled with the second path 620 and the third path 630. The slit 660 may make impedance matching when the first path 640 is coupled with the second path 620 and the third path 630.

FIG. 7A is a view illustrating the first portion 510, a through-hole 710 (e.g., the first through-hole 512 of FIG. 5A), a first path 740 (e.g., the first path 542 of FIG. 5A), a second path 720 (e.g., the fifth path 522 of FIG. 5A), and a third path 730 (e.g., the ninth path 532 of FIG. 5A), according to an embodiment. FIG. 7A may be a top view of a structure 700.

In an embodiment, the through-hole 710 may be formed at the first portion 510. For another example, a non-conductive material may be disposed in the through-hole 710. A relative dielectric constant of the non-conductive material may be, for example, about 3.5.

In an embodiment, a default resonant frequency of a radiator may be set by a length of a slot such as the through-hole 710. For example, a length of the through-hole 710 in the first direction (i.e., X-axis) may be about 3.6 mm and a length of the through-hole 710 in the second direction (i.e., Y-axis) may be about 1.0 mm. In this case, the through-hole 710 may have a length of about 0.5 λg or more and about 0.6 λg or less at about 28 GHz that is used in 5G communication. “λg” may be defined as a wavelength in waveguide being a wavelength m the through-hole 710.

In an embodiment, the first path 740 may have a line width of about 0.23 mm or more and about 0.7 mm or less in the first direction (i.e., X-axis) and may have a length of about 3.3 mm in the second direction (i.e., Y-axis). For example, as a distance from one side at which the first path 740 is coupled with the second path 720 and the third path 730 decreases, a line width of the first path 740 may increase. The first path 740 may function as an impedance transformer.

In an embodiment, the second path 720 and the third path 730 may include overlapping parts 721 and 731, at least portions of which overlap the through-hole 710 after being branched from the first path 740, and open stubs 722 and 732 (e.g., 621 and 631 of FIG. 6) disposed at portions passing through the through-hole 710. A line width of the overlapping parts 721 and 7311 in the first direction (i.e., X-axis) may be about 0.23 mm. A length of the overlapping parts 721 and 731 in the second direction (i.e., Y-axis) may be about 1.5 mm. A line width of the open stubs 722 and 732 in the first direction (i.e., X-axis) may be about 0.1 mm. A length of the open stubs 722 and 732 in the second direction (i.e., Y-axis) may be about 1.2 mm. Also, each of the second path 720 and the third path 730 may be spaced from the center of the through-hole 710 as much as about 1.6 mm. As such, the second path 720 and the third path 730 may be spaced from each other as much as about 3.2 mm.

FIG. 7B is a view illustrating a substrate 750 including the first portion 510 and a feeding part 760 in detail, according to an embodiment. FIG. 7B may be a side view of the structure 700. The first portion 510 of FIG. 7B may include through-holes 710. The feeding part 760 of FIG. 7B may include the first path 740, the second path 720, and/or the third path 730.

In an embodiment, the through-holes 710 may be formed at the first portion 510. A thickness of the first portion 510 in a height direction (Z-axis) may be about 0.5 mm.

In an embodiment, the first path 740 may be connected with the second path 720 and/or the third path 730. The first path 740 may transfer a signal to the second path 720 and/or the third path 730.

In an embodiment, the substrate 750 may include a plurality of feeding parts 760. For example, a conductive layer including the feeding part 760 may be disposed within the substrate 750. The substrate 750 may face one surface of the first portion 510 including the through-hole 710. A dielectric layer 770 formed of a dielectric of a non-conductive characteristic may be included between the feeding part 760 included in the substrate 750 and the first portion 510. A thickness of the dielectric layer 770 in the height direction (i.e., Z-axis) may be about 0.1 mm. For another example, a gap of about 0.1 mm may be formed between the feeding part 760 and the first portion 510.

In an embodiment, the first to fourth through-holes 812, 814, 816, and 818 may have substantially the same structure and function as the through-holes 512, 514, 516, and 518 described with reference to FIG. 5A. Thus, below, additional description associated with the through-holes 812, 814, 816, and 818 will be omitted to avoid redundancy.

In an embodiment, the first to eighth conductive paths 822, 824, 826, 828, 832, 834. 836, and 838 may be extended in the second direction (i.e., Y-axis). The first to eighth conductive paths 822, 824, 826, 828, 832, 834, 836, and 838 may be disposed over the first to fourth through-holes 812, 814, 816, and 818 with respect to the Z-axis direction.

In an embodiment, the first to eighth conductive paths 822, 824, 826, 828, 832, 834, 836, and 838 may form a feeding part. The first to eighth conductive paths 822, 824, 826, 828, 832, 834, 836, and 838 may be connected with a. wireless communication circuit 940. The first to eighth conductive paths 822, 824, 826, 828, 832, 834, 836, and 838 may be fed with a signal of a frequency to be radiated from the wireless communication circuit 940.

As such, the first to eighth power amplifiers 842, 844, 846, 848, 852, 854, 856, and 858 may be used as much as the number of first to eighth conductive paths 822, 824, 826, 828, 832, 834, 836, and 838. For example, in the case where the number of first to fourth through-holes 812, 814, 816, and 818 is “4”, 8 chains may be used. In the case of feeding the first through-hole 812 by using the first and second conductive paths 822 and 832, a power gain may be increased as much as 3 dB compared to the case of feeding the first through-hole 812 by using one conductive path.

For example, the first through-hole 910 may have a structure in which the first slit 912 and the second slit 914 of a rectangular form cross each other at a central portion thereof. As elongated portions of the first slit 912 and the second slit 914 are disposed to have different directions, the first through-hole 910 may generate polarizations in different directions at the first slit 912 and the second slit 914.

A polarization generated by the first slit 912 and a polarization generated by the second slit 914 may be perpendicular to each other. For example, a vertical polarization (V-pol.) in the second direction (i.e., Y-axis) may be formed by the first slit 912, and a horizontal polarization (H-pol.) in the first direction (i.e., X-axis) may be formed by the second slit 914.

In the third through-hole 1010, the sixth slit 1014 may be formed to penetrate a central portion of the fifth slit 1012. As in the above description, the seventh slit 1022 may be elongated in the third direction D3, and the eighth slit 1024 may be elongated in the fourth direction D4.

In an embodiment, as the fifth slit 1012 and the sixth slit 1014 forming the third through-hole 1010 are disposed to cross at right angles, there may be formed polarizations crossing at right angles. For example, a polarization in the fourth direction D4 may be formed by the fifth slit 1012 elongated in the third direction D3, and a polarization in the third direction D3 may be formed by the sixth slit 1014 elongated in the fourth direction D4.
