Referring to FIG. 3A , a UWB antenna 200 included in an electronic device (eg, the electronic device 101 of FIG. 1 ) according to various embodiments may transmit a UWB frequency signal (eg, about 6.2G to 8.2GHz). A plurality of patch elements (eg, the first patch element 210 to the third patch element 230 ) may be set to be disposed within a wavelength range 310 (eg, within λ/2). The position of the UWB antenna 200 may be adjusted so that a plurality of patch elements (eg, the first patch element 210 to the third patch element 230) are disposed within the wavelength range 310 . Alternatively, in the UWB antenna 200 , the position of the feeding line is such that the feeding line connected to the plurality of patch elements (eg, the first patch element 210 to the third patch element 230 ) is disposed within the wavelength range 310 . It can be changed (or adjusted). The first patch element 210 to the third patch element 230 may be connected to the connection circuit 240 through a plurality of feeding lines. For example, the first distance D1 between the first patch element 210 and the second patch element 220 may include a plurality of feeding lines connected to the first patch element 210 within the wavelength range 310 and the second patch. A plurality of feeding lines connected to the element 220 may be adjusted to be disposed. A distance FD1 between the plurality of feeding lines connected to the first patch element 210 and the plurality of feeding lines connected to the second patch element 220 may be approximately 10 mm to 30 mm. The first distance D1 between the first patch element 210 and the second patch element 220 may be adjusted such that the first patch element 210 and the second patch element 220 are disposed within the wavelength range 310 . have. Alternatively, the second distance D2 between the second patch element 220 and the third patch element 230 is adjusted so that the second patch element 220 and the third patch element 230 are disposed within the wavelength range 310 . can be The second distance D2 between the second patch element 220 and the third patch element 230 is a plurality of feeding lines connected to the second patch element 220 within the wavelength range 310 and the third patch element 230 . A plurality of feeding lines connected to may be adjusted to be disposed. A distance FD2 between the plurality of feeding lines connected to the second patch element 220 and the plurality of feeding lines connected to the third patch element 230 may be approximately 10 mm to 30 mm.

For example, when the UWB antenna 200 is configured within the wavelength range 310 , the electronic device 101 displays external electrons within a field of view (FOV) area (eg, about -60 degrees to +60 degrees). It can measure a wider range of linear angle of arrival (AOA) or high phase resolution values for devices. When the feeding distance between each patch element is out of the wavelength range 310 of the UWB frequency signal, the electronic device 101 may measure the non-linear AOA through the UWB antenna 200 . The wavelength range 310 may be flexible depending on the frequency used for UWB communication. As the frequency increases, the wavelength range can be relatively small (eg λ = ν/f).

3B is a diagram illustrating another example of forming a UWB antenna structure within a wavelength range according to various embodiments.

Referring to FIG. 3B , when the electronic device 101 forms at least one patch element (eg, the third patch element 230 ) out of the wavelength range 310 , the third patch element included in the UWB antenna 350 . The position of the patch element 230 or the positions of the plurality of feeding lines F5 and F6 connected to the third patch element 230 may be changed. The change in the position of the feed line of the third patch element 230 may be to have the same frequency resonance characteristic as that of the UWB antenna 200 that forms all the patch elements within the wavelength range 310 . For example, the first patch element 210 and the second patch element 220 are spaced apart by a first distance D1, and the second patch element 220 and the third patch element 230 are spaced apart by a third distance D1. D3) can be spaced apart. The third distance D3 is a second distance D2 between the second patch element 220 and the third patch element 230 in the UWB antenna 200 in which the third patch element 230 is formed within the wavelength range 310 . (eg, FIG. 2A ). Since the UWB antenna 350 secures the third distance D3 larger than the second distance D2 , the electronic device 101 may measure the linear AOA.

The position of the second feeding line F6 of the third patch element 230 may be changed to be included in the wavelength range 310 . The position of the first feeding line F5 may also be changed according to the change of the position of the second feeding line F6 .

Referring to FIG. 4 , the AOA measurement graph 400 may show the AOA measurement results according to the feeding distances (the first feeding distance 410 to the third feeding distance 430 ) between feeding lines connected to the patch element. have. Looking at the AOA measurement graph 400 , a linear AOA measurement may be possible only when the measurement slope of the AOA according to the phase is maintained over a certain standard (eg, 30 degrees). When the measurement slope of AOA does not satisfy certain criteria, non-linear AOA may be measured. The AOA measurement result shown in the AOA measurement graph 400 is for helping understanding of the invention, and may not be absolutely determined by the feeding distance.

The feeding distances 410 to 430 are the second feeding line F2 of the first patch element (eg, the first patch element 210 of FIG. 3B ) and the second patch element (eg, the second patch element of FIG. 3B ). (220) the feeding distance FD1 between the first feeding line F3 or the second feeding line F4 of the second patch element 220 and the third patch element (eg, the third patch element in FIG. 3B ) 230)) may mean a feeding distance FD2 between the first feeding lines F5. The first feeding distance 410 (eg 12 mm) is greater than the second feeding distance 420 (eg 10 mm), and the second feeding distance 420 is greater than the third feeding distance 430 (eg 9 mm). can

When the feeding distance between the feeding lines connected to the patch element, such as the first feeding distance 410 or the second feeding distance 420, is within the wavelength range 310 (or a certain distance (eg, about 10 to 30 mm)) ), the electronic device 101 may measure the linear AOA. When the electronic device 101 measures a distance through UWB communication, linear AOA measurement may be required. Like the third feeding distance 430 , when the feeding distance between the feeding lines connected to the patch element is out of the wavelength range 310 (or less than a certain distance (eg, 9 mm)), the electronic device 101 is non-linear AOA can be measured. When measuring the non-linear AOA, the electronic device 101 may not be able to utilize the measured AOA. Accordingly, the arrangement position of the patch element included in the UWB antenna 200 or the position of the feeding line may be determined in consideration of the feeding distance for measuring the linear AOA.

The first patch element 210 to the third patch element 230 may be connected to the connection circuit 240 through a plurality of feeding lines. A feeding space (eg, the first feeding space S1 to the third feeding space S3) may be formed by a plurality of feeding lines connected to each patch element.

For example, the first feeding space S1 may be formed by a first feeding line F1 and a second feeding line F2 connected to the first patch element 210 . Alternatively, the first feeding space S1 may be a space formed when the outer line of the first patch element 210 and the first feeding line F1 are connected to the second feeding line F2 . The second feeding space S2 may be formed by the first feeding line F3 and the second feeding line F4 connected to the second patch element 220 .

The electronic device 101 increases the feed distance between the second feed line F4 connected to the second patch element 220 and the first feed line F5 connected to the third patch element 230 to form a linear AOA. can be measured. The feeding distance FD4 between the second feeding line F4 connected to the second patch element 220 and the first feeding line F5 connected to the third patch element 230 is the second patch element shown in FIG. 3A ( It may be greater than the feeding distance FD2 between the second feeding line F4 connected to 220 and the first feeding line F5 connected to the third patch element 230 . Referring to the AOA measurement graph 400 of FIG. 4 , the electronic device 101 may measure linear AOA by improving the coupling coefficient and isolation characteristics of each patch element as the feeding distance is closer to the wavelength range 310 . can

According to various embodiments, the shape of the feeding space formed by the feeding line may vary according to a change in the position of the feeding line connected to the patch element. The first feeding space S1 to the third feeding space S3 may have different shapes. The first feeding space S1 to the third feeding space S3 may have the same area (eg, the size of the area). The shape of the feeding space formed by the feeding line may be different, but the width of the feeding space may be the same.

According to various embodiments, the UWB antenna 500 may adjust the AOA linear characteristics of each patch element by adjusting the positions of the plurality of feed lines without changing the positions of the patch elements so that the patch elements are disposed within the wavelength range. have. When adjusting the positions of the plurality of feeding lines, the width of the feeding space may need to be maintained the same. For example, when the distance between the patch elements in the UWB antenna 500 is fixed, the feeding space formed by the patch element and the feeding line may be adjusted without adjusting the resonant frequency band. Also, by adjusting the feeding distance between the feeding lines connected to the patch element (FD1→FD3, FD2→FD4), the electronic device 101 may measure the AOA having a wider resolution. In this case, the width of the feeding space of each patch element may be the same. For example, an area of the first feeding space S1 , an area of the second feeding space S2 , and an area of the third feeding space S3 may be equal to each other.

The UWB antenna 500 may dispose the first patch element 210 within a wavelength range and change positions of a plurality of feeding lines to be connected to the first patch element 210 in order to obtain a linear AOA. For example, according to a change in the positions of the plurality of feeding lines to be connected to the first patch element 210 , the first patch element 210 and the first feeding line F1 and the second feeding line connected to the first patch element 210 are changed. A second feeding space 630 having a third width W3 and a third height H3 may be formed by the feeding line F2 . The second width W2 may be equal to or smaller than the third width W3 . The second height H2 may be equal to or greater than the third height H3 . For example, when the third width W3 is wider than the second width W2 , the third height H3 may be lower than the second height H2 . When the positions of the plurality of feeding lines to be connected to the first patch element 210 are changed (eg, second height H2 -> third height H3, second width W2 -> third width W3) , by maintaining the same width of the feeding space, the electronic device 101 may similarly control the resonant frequency band of the first patch element 210 . The first feeding space 610 or the second feeding space 630 may have a different shape, but may have the same width.

According to various embodiments, the electronic device 101 adjusts the relative positions of the plurality of feed lines for each patch element having the same size, so that isolation between the patch elements is improved to improve antenna performance (eg, efficiency (Gain)) can improve

The first patch element 210 and the second patch element 220 may have different antenna resonant frequency bands according to different shapes of the feeding space. Conversely, each patch element may have the same antenna resonant frequency band, even if it forms a different type of feeding space.
