[0041] According to one embodiment, the matching unit (230) may include a plurality of paths connected in parallel between a (a) terminal corresponding to a feed point that electrically connects an antenna radiator (e.g., antenna (240) in FIG. 2) and a feed line, and a (b) terminal that electrically connects an RF module (e.g., RF module (220) in FIG. 2) and a feed line. Each of the plurality of paths connecting in parallel between the (a) terminal and the (b) terminal may be a feed line that is an independent RF signal transmission line. The plurality of paths may include, for example, a first path (e.g., main path or primary path) and one or more second paths (e.g., matching path or auxiliary path).

The second point (340) may be located between the (b) terminal connecting the RF module and the feed line and the lump element (320).

[0042] According to one embodiment, one or more second paths may be divided into a 2-1 section (350) that electrically connects the first point (330) and the tuner (310) and a 2-2 section (360) that electrically connects the second point (340) and the tuner (310). The number of second paths in the 2-1 section (350) that electrically connects the first point (330) and the tuner (310) l ) is the number of second paths existing in the 2-2 section (360) electrically connecting the second point (340) and the tuner (310) n It may be the same as or different from ). The number of second paths in section 2-1 (350) l The number of second paths existing in ) and the 2-2 section (360)n ) can be a positive integer.

[0043] According to one embodiment, inside the tuner (310), there is a section 2-1 (350) existing l A lump element may be placed in at least one of the two second paths, or may not be placed, and the 2-2 section (360) existing n A lump element may be placed in at least one of the two second paths, or may not be placed. The tuner (310) may have a structure of one of FIG. 4a, FIG. 4b, or FIG. 4c, for example, described below.

[0044] FIGS. 4a to 4c illustrate examples of the structure of a tuner (310) described with reference to FIG. 3. The structure of the tuner (310) illustrated in FIGS. 4a to 4c can be divided into the arrangement of at least one lump element. FIGS. 4a and 4b illustrate examples of the structure of a tuner (310) in which one lump element is arranged, and FIG. 4c illustrates examples of the structure of a tuner (310) in which two lump elements are arranged.

[0045] Referring to FIGS. 4a through 4c, a tuner (310) according to one embodiment may include at least one rump element (420, 430) and a switch circuit (410). The at least one rump element (420, 430) and the switch circuit (410) may be arranged in series between a first point (e.g., the first point (330) in FIG. 3) and a second point (e.g., the second point (340) in FIG. 3). Since FIG. 3 illustrates that the tuner (310) is connected in parallel to a power supply line, it can be seen that the switch circuit (410) is also arranged in a parallel structure with respect to the power supply line. The at least one rump element (420, 430) may include, for example, a passive element (e.g., a resistor (R), an inductor (L), or a capacitor (C)) or a combination of passive elements. At least one rump element (420, 430) may include, for example, a capacitor having a predetermined capacitance or an inductor having a predetermined inductance.

[0046] According to one embodiment, the switch circuit (410) can form various antenna impedance matching topologies to improve the transfer performance of energy, such as RF signals, between a feed line and an antenna by considering at least one rump element (420, 430). The various impedance matching topologies can provide a multipath (e.g., matching paths) that electrically connects a first point (330) and a second point (340). The switch circuit (410) may include at least two terminals (440, 450). Of the at least two terminals (440, 450) included in the switch circuit (410), at least one terminal may be used as an input terminal, and the other at least one terminal may be used as an output terminal. For example, when the switch circuit (410) includes a first terminal (440) and a second terminal (450), the first terminal (440) may be used as an output terminal and the second terminal (450) may be used as an input terminal during an operation to transmit an RF signal. For another example, when the switch circuit (410) includes a first terminal (440) and a second terminal (450), the first terminal (440) may be used as an input terminal and the second terminal (450) may be used as an output terminal during an operation to receive an RF signal.

However, the pole terminal can be made open so that parasitic resonance is not output to the antenna radiator, thereby ensuring that there is no physically grounded rump element. At least one of the at least two throw terminals in the switch circuit (410) can be electrically connected between the (a) terminal (e.g., the feed point (a) connecting the antenna (240) and the matching part (230) in FIG. 2) and the rump element (e.g., the rump element (320) in FIG. 3) (e.g., at least one first point (330)). Of the at least two throw terminals in the switch circuit (410), the remaining at least one throw terminal can be connected between the (b) terminal (e.g., the (b) terminal connecting the matching part (230) and the RF module (220) of FIG. 2) and the rump element (320) (e.g., at least one second point (340)).

Such a switching circuit (410) is designed so that only internal capacitance exists, thereby preventing parasitic resonance caused by shunt matching in the frequency band of 6 GHz or lower.

In this case, the impedance matching topology of the antenna may have a structure in which one point (330b) located between the antenna radiator (240) and the lump element (320) placed on the feed line is connected to ground through another lump element (420b) (see (b)).

In this case, the impedance matching topology of the antenna may have a structure in which the first point (330b) and the second point (340a) on the feed line are each connected to ground through different lump elements (420b, 430a), and the third point (330a) and the fourth point (340b) on the feed line are connected through another lump element (420a, 430b) (see (b)).

The four throw terminals (first to fourth terminals) may be electrically connected to any points (911, 913, 915, 917) of a feed line through a predetermined rump element. As previously described, the feed line may be a transmission line that electrically connects a feed point (a) and an RF module (b). The switching circuit (930) may include four switches (sw1, sw2, sw3, sw4) (e.g., four switches (sw1, sw2, sw3, sw4) of FIG. 7 (710, 720, 730, 740)) and four stoppers (sh1, sh2, sh3, sh4) (e.g., four stoppers (sh1, sh2, sh3, sh4) (750, 760, 770, 780)). The four switches (sw1, sw2, sw3, sw4) and four stoppers (sh1, sh2, sh3, sh4) may be arranged according to a predetermined pattern between a first terminal and a third terminal or between a second terminal and a fourth terminal. For example, the first and fourth switches (sw1, sw4) may be arranged in series between the first terminal and the fourth terminal, and the second and third switches (sw2, sw3) may be arranged in series between the second terminal and the third terminal.
