According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).
[0045] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)).

For example, the tuning unit (320) can short-circuit at least one of the switch (322) and the switch (323) and adjust the electrical capacitance of the variable capacitor (321) under the control of the electronic device (300). Based on the combination of the lumped elements (331, 332) and the adjustment of the electrical capacitance of the variable capacitor (321), the electrical length and the operating frequency band of the radiator including the first conductive portion (311) and the second conductive portion (312) can be adjusted.

[0093] FIG. 6 is a drawing showing an example of a tuning section connected to electronic components according to one embodiment.
[0094] The tuning unit (420) of Fig. 6 may correspond to the tuning unit (320) of Fig. 3.
[0095] Referring to FIG. 6, in one embodiment, the tuning unit (420) may be implemented as an IC (integrated circuit) chip including a variable capacitor (410), a first switch (421), a second switch (422), a third switch (423), a fourth switch (424), and / or a fifth switch (425).

[0097] According to one embodiment, the variable capacitor (410) is disposed between the first conductive portion (311) and the second conductive portion (312), such that both ends of the variable capacitor (410) can be electrically connected to the first conductive portion (311) and the second conductive portion (312) via the first switch (421) and the second switch (422). For example, one end of the variable capacitor (410) can be electrically connected to a first protrusion (41) protruding from the first conductive portion (311) via the first switch (421) and the first capacitor (631). For example, the other end of the variable capacitor (410) can be electrically connected to a second protrusion (42) protruding from the second conductive portion (312) via the second switch (422) and the second capacitor (632).
[0098] According to one embodiment, a third switch (433) and a third capacitor (633) may be additionally connected between one end of the variable capacitor (410) and the first protrusion (41). The third switch (433) and the third capacitor (633) may be connected in parallel with the first switch (421) and the first capacitor (631).
[0099] According to one embodiment, a fourth switch (434) and a fourth capacitor (634) may be additionally connected between the other end of the variable capacitor (410) and the second protrusion (42). The fourth switch (434) and the fourth capacitor (634) may be connected in parallel with the second switch (422) and the second capacitor (632).
[0100] According to one embodiment, at least some of the capacitors (631, 632, 633, 634) connected to the switches in the tuning unit (420) may have different element values. For example, a first capacitor (631) connected to a first switch (421) may have a capacitance value of C1, a second capacitor (632) connected to a second switch (422) may have a capacitance value of C2, a third capacitor (633) connected to a third switch (423) may have a capacitance value of C3, and a fourth capacitor (634) connected to a fourth switch (424) may have a capacitance value of C4.

In addition, an RF signal of an operating frequency band corresponding to the adjusted electrical length of the radiator can be radiated through the radiator.
[0104] For example, the range of the electrostatic capacitance of the variable capacitor (410) in the tuning unit (420) may be 0.75 pF to 9 pF, and the electrostatic capacitance may be adjusted by dividing into 30 states. In this case, it may be difficult to secure optimized performance of the antenna depending on the LB frequency band. Accordingly, for example, if C1, C2, C3, and C4 of FIG. 6 are all made to have different values, 16 electrostatic capacitance values may be provided depending on the combination of C1, C2, C3, and C4. In this case, the variable capacitor (410) may be adjusted to 30 electrostatic capacitance values, and by short-circuiting at least one of the first switch (421), the second switch (422), the third switch (423), the fourth switch (424), or the fifth switch (425), the electrical length of the radiator may be adjusted to 480 (= 30 * 16) states.
