In an embodiment, the second conductive patch 1820 and/or the third conductive patch 1830 may have substantially the same shape as the first conductive patch 310 . For example, the second conductive patch 1820 and/or the third conductive patch 1830 may have a rectangular fifth area removed from a rectangular shape like the first conductive patch 1810 described with reference to FIG. 18 . can have

According to an embodiment, the second conductive patch 1820 includes a fifth edge 1825, a sixth edge 1826, and a sixth edge 1826 meeting at a fifth edge 1825 and a fifth corner 1820a.

According to an embodiment, the third conductive patch 1830 may include a ninth edge 1839, a tenth edge 1840, and a tenth edge 1840 meeting at a ninth edge 1839 and a ninth corner 1830a.

According to an embodiment, the plurality of conductive patches 300 may be substantially equally arranged. For example, the first slit structure 1850 of the first conductive patch 1810 has a first width W1 in the x-axis direction and a second width W2 smaller than the first width W1 in the y-axis direction. ) can be arranged to have In one example, the second conductive patch 320 may be disposed to have a third width W3 in the x-axis direction and a fourth width W4 smaller than the third width W3 in the y-axis direction. .

As a result, the plurality of conductive patches 300 may be substantially identically arranged.

According to an embodiment, the plurality of conductive patches 1800 may be spaced apart from each other along a designated axis.

The third conductive patch 1830 may be spaced apart from the second conductive patch 1820 along a second axis (eg, a y-axis).

Power may be supplied to a point adjacent to a corner that is located along the transmission line 2030 and minimizes the length of the transmission line 2030 .

Among the corners of the first conductive patch 1810, corners located along the third axis include a first corner 1810a and a third corner 1810c, but a corner capable of minimizing the length of the first transmission line 2031. Since corresponds to the first corner 1810a, the wireless communication circuit 360 may supply power to the first point P1 adjacent to the first corner 1810a through the first transmission line 2031. The electronic device 101 can reduce loss due to signal transmission by minimizing the length of the first transmission line 2031 .

Among the corners of the second conductive patch 1820, corners located along the third axis include a fifth corner 1820a and a seventh corner 1820c, but a corner capable of minimizing the length of the second transmission line 2032. Since corresponds to the seventh corner 1820c, the wireless communication circuit 360 may supply power to the seventh point P7 adjacent to the seventh corner 1820c through the second transmission line 2032.

The electronic device 101 can reduce loss due to signal transmission by minimizing the length of the third transmission line 2033 .

According to an embodiment, when the plurality of conductive patches 1800 are disposed with substantially the same arrangement, the wireless communication circuit 360 may include a designated axis among corners of each of the plurality of conductive patches 1800 (eg: The directions of the circularly polarized waves can be matched by feeding power to a corner located along the third axis or the fourth axis). For example, the wireless communication circuit 360 may supply power to a first point P1 of the first conductive patch 1810 and may supply power to a sixth point P6 of the second conductive patch 1820. . In this case, circular polarization in the LHCP direction may be formed in the first conductive patch 1810, and circular polarization in the RHCP direction may be formed in the second conductive patch 1820. If the circularly polarized waves formed in the first conductive patch 1810 and the second conductive patch 1820 have different directions, performance of the electronic device 101 may deteriorate when performing UWB communication. On the other hand, if the wireless communication circuit 360 according to an embodiment supplies power to the first point P1 of the first conductive patch 1810 and the seventh point P7 of the second conductive patch 1820, the first conductive patch Circular polarization in the LHCP direction may be formed in the patch 1810 and the second conductive patch 1820, respectively. Therefore, the electronic device 101 can prevent performance degradation during UWB communication by matching the directions of circularly polarized waves respectively formed in the plurality of conductive patches 1800 .

According to an embodiment, as the plurality of conductive patches 1800 are arranged in a substantially identical arrangement, the electronic device 101 may change the direction and/or circular direction of linear polarization formed in each of the plurality of conductive patches 1800. The direction of the polarization can be matched. For example, it may be assumed that the second conductive patch 1820 is rotated by +90 degrees and disposed differently from that shown in FIG. 18 . In this case, the fifth edge 1825 of the second conductive patch 1820 rotated by +90 degrees may be disposed parallel to the x-axis. The wireless communication circuit 360 may supply power to the first point P1 of the first conductive patch 1810 through the first transmission line 2031, and the second conductive patch rotated by +90 degrees through the additional transmission line. Power can be supplied to the fifth point P5 of (1820). In this case, in the first conductive patch 1810, a first linear polarized wave crossing the first conductive patch 1810 in the +y direction and a second linear polarized wave crossing the second conductive patch 1820 in the +z direction are formed. It can be. In the second conductive patch 1820, a third linear polarized wave crossing the second conductive patch 1820 in the +x direction and a fourth linear polarized wave crossing the second conductive patch 1820 in the +y direction may be formed. . As a result, directions of the first linear polarization and the third linear polarization corresponding to the first linear polarization may be different, and directions of the second linear polarization and the fourth linear polarization corresponding to the second linear polarization may be different. When the electronic device 101 performs UWB communication, performance may be deteriorated because the directions of the linearly polarized waves respectively formed in the first conductive patch 1810 and the second conductive patch 1820 are different. On the other hand, according to an embodiment, the first width W1 of the first conductive patch 1810 is disposed parallel to the x-axis and the third width W3 of the second conductive patch 1820 is parallel to the x-axis. According to the arrangement, the directions of the linearly polarized waves respectively formed in the first conductive patch 1810 and the second conductive patch 1820 may coincide. As a result, the electronic device 101 can prevent degradation of UWB communication performance by matching the directions of linear polarization and/or circular polarization formed in the plurality of conductive patches 300 .
