[0086] Fig. 9 and Fig.10 Schematic diagram of the structure of the radiation part 2 and the feeding part 3 in different implementation modes of this embodiment. Fig. 9 and Fig.10 The first side 23 in FIG. 2 is shown by a dotted line, and the second side 24 is shown by a dashed line. Fig.10 The outline of the radiation part 2 shown by the thin solid line is a rectangle, and the edge of the outline of the radiation part 2 shown by the dashed line is partially located outside the rectangle. The inner edge of the strip-shaped conductor 63 is shown by the dotted line.

[0087] In some embodiments, Figure 1-Figure 2 As shown, the ultra-wideband antenna in this embodiment includes a radiating portion 2 , a feeding portion 3 and a grounding portion 4 .

[0088] Further reference Fig. 9 and Fig.10 As shown, the radiation portion 2 is spaced apart from and coupled to the ground portion 4, and the radiation portion 2 has two first side edges 23, a first feeding point 21 and a second feeding point 22, and the first feeding point 21 and the second feeding point 22 are electrically connected to the feeding portion 3. The first side edge 23 includes a first extension segment 231, and the first extension segment 231 extends in a straight line. The first feeding point 21 and the second feeding point 22 are respectively arranged corresponding to the two first extension segments 231 located on the two first side edges 23.

[0089] Specifically, the coupling modes of the radiation part 2 and the ground part 4 in this embodiment include direct coupling and indirect coupling. Direct coupling may be that no wave conductor is provided between the radiation part 2 and the ground part 4, so that the radiation part 2 and the ground part 4 interact with each other through electromagnetic waves. Indirect coupling may be that a wave conductor is provided between the radiation part 2 and the ground part 4, so that electromagnetic waves are conducted between the radiation part 2 and the ground part 4 through the wave conductor.

[0090] The first feeding point 21 and the second feeding point 22 are located between the two first sides 23 , and the distance from the first feeding point 21 to the corresponding first extension section 231 is the same as the distance from the second feeding point 22 to the corresponding first extension section 231 , that is, the distance L8 is the same as the distance L9 .

[0091] In summary, the ultra-wideband antenna in this embodiment couples the radiating part 2 with the grounding part 4, and simultaneously sets the first feeding point 21 and the second feeding point 22 on the radiating part 2, and sets the first feeding point 21 and the second feeding point 22 corresponding to the two first extension sections 231. As a result, the guided electromagnetic waves fed by the feeding part 3 to the radiating part 2 are mutually offset in the arrangement direction of the first feeding point 21 and the second feeding point 22, thereby generating guided electromagnetic waves conducted along the extension direction of the first side 23. Furthermore, by controlling the length of the first side 23, the ultra-wideband antenna radiates electromagnetic waves. The operating frequency and the operating bandwidth are improved. On the other hand, by simultaneously using the first feeding point 21 and the second feeding point 22 to feed the guided electromagnetic waves to the radiating part 2, the two first sides 23 can both affect the radiation of the electromagnetic waves, thereby improving the beam width of the ultra-wideband antenna and having better symmetry.

[0092] In some embodiments, Fig. 9 and Fig.10 As shown, the radiating portion 2 further includes a second side 24, the second side 24 includes a second extension section 241, the second extension section 241 extends in a straight line, and the second side 24 is connected to the ends on the same side of the two first side 23. In a direction perpendicular to the second extension section 241, the first feeding point 21 and the second feeding point 22 are at the same distance from the second extension section 241. That is, the distance L3 is equal to the distance L4.

[0093] Therefore, in this embodiment, the potential difference from the first feeding point 21 and the second feeding point 22 to the second side 24 is kept consistent, so that in the arrangement direction of the first feeding point 21 and the second feeding point 22, the potentials on the second side 24 cancel each other out, ensuring that the radiating part 2 can excite electromagnetic waves by controlling the length of the first side 23.

[0094] In some embodiments, Figure 9-10 As shown, the second side includes two second extension sections 241 and a second curved section 242, the second curved section 242 is connected between the two second extension sections 241, and the second curved section 242 is bent toward the center of the radiating portion 2. The first feeding point 21 and the second feeding point 22 are symmetrically arranged relative to the second curved section 242. That is, the distance L1 is equal to the distance L2.

[0095] The radiation portion 2 in this embodiment includes two first curved segments 232 and two second curved segments 242. The first curved segment 232 and the second curved segment 242 can increase the length of the first side 23 and further reduce the occupied area of ​​the radiation portion 2. At the same time, in order to ensure the impedance characteristics of the first signal feeding point 21 and the second signal feeding point 22, the first curved segment 232 and the second curved segment 242 are also arranged corresponding to the center of the radiation portion 2, so that the radiation portion 2 as a whole has a high degree of symmetry.

[0096] In some embodiments, Fig. 9 and Fig.10 As shown, there are two second sides 24, and the second curved sections 242 of the two second sides 24 are arranged opposite to each other. The first side 23 also includes a first curved section 232, and there are two first extension sections 231, the first curved section 232 is connected between the two first extension sections 231, the two first curved sections 232 are arranged opposite to each other and bend toward the center of the radiation portion 2, and the first extension section 231 is vertically connected to the second extension section 241.

[0097] In this embodiment, the two first curved sections 232 and the two second curved sections 242 are symmetrically arranged along the center point of the radiating portion 2, and the first extending section 231 and the second extending section 241 are configured to be perpendicular to each other, which can maximize the impedance characteristics of the radiating portion 2 in all directions.

[0098] In some embodiments, Figure 2 and Figure 7 As shown, the ultra-wideband antenna further includes a dielectric portion 5. The dielectric portion 5 has a first layout surface 51 and a second layout surface 52 which are spaced apart and arranged in parallel.

[0099] The radiating portion 2 includes a radiating pattern arranged on a first layout surface 51 , and the grounding portion 4 includes a grounding pattern arranged on a second layout surface 52 , and in a direction perpendicular to the first layout surface 51 , a projection of the radiating pattern on the second layout surface 52 is located inside the grounding pattern.

[0100] The material of the dielectric part 5 in this embodiment can be RF4 or other materials, and the radiation performance of the ultra-wideband antenna can be effectively improved by using the dielectric part 5. At the same time, the grounding part 4 is arranged at the bottom of the radiating part 2 and completely corresponds to the radiating part 2. Thus, the oscillation effect of the guided electromagnetic wave between the grounding part 4 and the radiating part 2 is effectively improved.

[0101] In some embodiments, Figure 7 As shown, the medium portion 5 further has a third layout surface 53 which is arranged at an interval. The third layout surface 53 is arranged at an interval between the first layout surface 51 and the second layout surface 52 .

[0102] Further reference Fig. 9As shown, the feeding part 3 includes a signal distribution branch 31 and a feeding branch 32. The signal distribution branch 31 is arranged on the third layout surface 53 and has a first connection end 312, a second connection end 313 and a signal distribution area 311 located between the first connection end 312 and the second connection end 313, and the first connection end 312 and the second connection end 313 are electrically connected to the first feeding point 21 and the second feeding point 22 respectively. The feeding branch 32 is arranged on the third layout surface 53 and extends from the signal distribution area 311 to the edge of the third layout surface 53.

[0103] The feeding branch 32 in this embodiment extends to the edge of the dielectric portion 5 to facilitate the connection between the feeding portion 3 and the RF circuit. At the same time, the signal distribution branch 31 and the feeding branch 32 can be equivalent to a power divider to distribute the power of the guided electromagnetic waves output by the RF circuit.

[0104] In some embodiments, Figure 7 As shown, the number of the third layout surfaces 53 is multiple and arranged at intervals. Figure 6 and Fig. 9 As shown, the feeding portion 3 further includes a fourth connection portion 33 and a fifth connection portion 34. The fourth connection portion 33 and the fifth connection portion 34 each include a plurality of second connection branches 35, the extension direction of the second connection branches 35 is parallel to the first extension section 231, and the plurality of second connection branches 35 are respectively arranged on a plurality of third arrangement surfaces 53. The first connection end 312 and the second connection end 313 are respectively connected to the first feeding point 21 and the second feeding point 22 through the fourth connection portion 33 and the fifth connection portion 34.

[0105] The plurality of second connecting branches 35 in this embodiment can increase the conduction length of the guided electromagnetic wave in the dielectric portion 5 and reduce the loss of the guided electromagnetic wave during the transmission process.

[0106] In some embodiments, Figure 6 , Figure 7 and Fig. 9 As shown, multiple second connection branches 35 extend along the same straight line, and in the direction perpendicular to the first layout surface 51, two adjacent second connection branches 35 partially overlap, and the second connection branch 35 close to the radiation pattern is closer to the first feeding point 21 or the second feeding point 22 than the second connection branch 35 far from the radiation pattern.

[0107] In this embodiment, when the plurality of second connection branches 35 of the third connection portion 13 are arranged one by one from bottom to top on the third layout surface 53, they will gradually approach the first feeding point 21. When the plurality of second connection branches 35 of the fourth connection portion 33 are arranged one by one from bottom to top on the third layout surface 53, they will gradually approach the second feeding point 22. Thus, the setting length of the second connection branches 35 on the dielectric portion 5 is guaranteed to reduce the insertion loss. At the same time, the length of the feeding branches 32 and the signal distribution branches 31 is also reduced to meet the impedance characteristic requirements of the feeding portion 3.

[0108] In some embodiments, Figure 6 and Figure 7 As shown, the fourth connection part 33 and the fifth connection part 34 both include a sixth conductive member 361, a seventh conductive member 362, and a plurality of eighth conductive members 363 located between the sixth conductive member 361 and the seventh conductive member 362. One end of the sixth conductive member 361 is connected to the second connection branch node 35, and the other end is connected to the first feeding point 21 or the second feeding point 22. One end of the seventh conductive member 362 is connected to the second connection branch node 35, and the other end is connected to the first connection end 312 or the second connection end 313. The sixth conductive member 361 is connected between two adjacent second connection branches 35, and in the direction perpendicular to the first layout surface 51, the sixth conductive member 361 is located in the overlapping area of ​​the two adjacent second connection branches 35.

[0109] In this embodiment, the sixth conductive member 361 , the seventh conductive member 362 and the eighth conductive member 363 are used so that the second connection branches 35 located on each third layout surface 53 can be connected to each other, further reducing the insertion loss of the feeding unit 3 .

[0110] Optionally, the first conductive member 61 and the second conductive member 62 in this embodiment are disposed in the connection hole 54 . The third conductive member 151 , the fourth conductive member 152 , the fifth conductive member 153 , the sixth conductive member 361 , the seventh conductive member 362 and the eighth conductive member 363 are disposed in the remaining mounting holes 55 .

[0111] Preferably, the first conductive member 61, the second conductive member 62, the third conductive member 151, the fourth conductive member 152, the fifth conductive member 153, the sixth conductive member 361, the seventh conductive member 362 and the eighth conductive member 363 in the present embodiment are conductive layers formed in the mounting hole 55. The conductive layer can be directly formed in the mounting hole 55 by a chemical copper plating process.

[0112] In some embodiments, Fig.10 As shown, the radiation pattern is rectangular. The radiation portion 2 further includes an extension structure 6, at least a portion of the extension structure 6 extends from the edge of the radiation pattern toward the ground pattern.

[0113] In this embodiment, the extension structure 6 can indirectly increase the size of the radiation portion 2, so that the radiation portion 2 has a smaller layout area than the above embodiment (eg Fig.10 As shown), while meeting the operating frequency of the ultra-wideband antenna, the ultra-wideband antenna occupies a smaller space.

[0114] Furthermore, the length position of the first side edge 23 is (1 / 4)λ 1 , the length of the second side 24 is (1 / 4)λ 2 , where λ 1 is the wavelength of the ultra-wideband antenna in the first operating frequency band, λ 2 is the wavelength of the ultra-wideband antenna in the second working frequency band. In this embodiment, the first side 23 and the second side 24 extend along a straight line and are vertically connected.

[0115] The first feeding point 21 and the second feeding point 22 in this embodiment enable the ultra-wideband antenna to have a first working state and a second working state. When the ultra-wideband antenna is in the first working state, the ultra-wideband antenna controls the length of the first side 23 so that the guided electromagnetic waves fed into the radiating portion 2 by the first feeding point 21 and the second feeding point 22 can excite electromagnetic waves in a lower frequency band. When the ultra-wideband antenna is in the second working state, the ultra-wideband antenna controls the length of the second side 24 so that the guided electromagnetic waves fed into the radiating portion 2 by the first feeding point 21 and the second feeding point 22 can excite electromagnetic waves in a higher frequency band.

[0116] In some embodiments, Figure 2 , Figure 4 and Figure 8 As shown, the dielectric portion 5 includes a plurality of connection holes 54, and the connection holes 54 extend from the first layout surface 51 to a third layout surface 53. The extension structure 6 includes a plurality of first conductive members 61 and a plurality of second conductive members 62, and the first conductive members 61 and the second conductive members 62 are both arranged in the connection holes 54, and the plurality of first conductive members 61 are arranged at intervals along at least one first side edge 23, and the plurality of second conductive members 62 are arranged at intervals along at least one second side edge 24.

[0117] Preferably, the connection hole 54 in this embodiment extends from the first layout surface 51 to the third layout surface 53 which is spaced apart from the first layout surface 51 by a third layout surface 53. Thus, the first conductive member 61 and the second conductive member 62 can have a sufficient length, thereby effectively compensating for the edge size of the radiation portion 2. At the same time, the impedance of the radiation portion 2 can also be adjusted.

[0118] In some embodiments, Figure 4 , Figure 8 and Fig.10As shown, the extension structure 6 further includes a strip conductor 63 , which is arranged on a third arrangement surface 53 and connected end to end. The first conductive element 61 and the second conductive element 62 extend from the radiation pattern to the strip conductor 63 .

[0119] Specifically, a first layout surface 51 is arranged between the third layout surface 53 and the first layout surface 51 on which the strip-shaped conductor 63 is laid. The inner edge and the outer edge of the strip-shaped conductor 63 are both rectangular, and in a direction perpendicular to the first layout surface 51, the outer edge of the strip-shaped conductor 63 coincides with the outer edge of the radiation pattern.

[0120] When the guided electromagnetic wave of the radiation pattern is transmitted through the first conductive member 61 and the second conductive member 62 to the strip conductor 63, it can be conducted along the extension direction of the strip conductor 63, so that the current conduction direction of the strip conductor 63 and the radiation pattern match each other, thereby achieving the purpose of reducing the size of the radiation pattern by using the extension structure 6.

[0121] In some embodiments, Figure 4 , Figure 8 and Fig.10 As shown, a plurality of first conductive members 61 are arranged along the two first side edges 23 , and a plurality of second conductive members 62 are arranged along the two second side edges 24 .

[0122] In the axial direction of the connection hole 54, the lengths of the first conductive member 61 and the second conductive member 62 are both L7. The distance L7 is the same as the axial length of the connection hole 54. The distance L7 is configured as L7 = ((1 / 4)λ 1 -L5)) / 2 and L7=((1 / 4)λ 2 -L6)) / 2. Among them, λ 1 is the wavelength of the ultra-wideband antenna in the first operating frequency band, λ 2 is the wavelength of the ultra-wideband antenna in the second working frequency band, L5 is the length of the first side 23 , and L6 is the length of the second side 24 .

[0123] In this embodiment, the sum of the lengths of the two first conductive members 61 and the first side 23 is equal to one quarter of the wavelength of the first working frequency band, and the sum of the lengths of the two second conductive members 62 and the second side 24 (eg Figure 8 As shown in FIG. 1 , which is equal to one quarter of the wavelength of the second working frequency band. Thus, the two groups of first conductive members 61 can extend the length of the first side 23, and the two groups of second conductive members 62 can extend the length of the second side 24. Thus, the layout area of ​​the radiation pattern is reduced.

[0124] In some embodiments, Fig.10As shown, the ultra-wideband antenna further includes a plurality of connection components 1. The connection components 1 are connected between the radiation portion 2 and the ground portion 4, the plurality of connection components 1 are arranged at intervals, and the first feeding point 21 and the second feeding point 22 are located at both sides of the connection component 1 respectively.

[0125] In this embodiment, the guided electromagnetic wave fed into the radiating portion 2 can oscillate between the radiating portion 2 and the grounding portion 4 through the multiple connecting components 1. The multiple connecting components 1 are arranged at intervals so that the radiating portion 2 generates a stable potential difference between the multiple connecting components 1 and the first side 23, thereby guiding the guided electromagnetic wave fed from the first feeding point 21.

[0126] It is easy to understand that the feeding part 3 in this embodiment can simultaneously feed the guided electromagnetic waves to the radiating part 2 through the first feeding point 21 and the second feeding point 22, so that the radiating part 2, the grounding part 4 and the multiple connecting components 1 can be equivalent to two symmetrically arranged resonant levels, further improving the radiation performance of the ultra-wideband antenna.

[0127] Further reference Figure 5 As shown, the connection assembly 1 further includes a plurality of conductive structures 15, the plurality of conductive structures 15 include a third conductive member 151, a fourth conductive member 152, and a plurality of fifth conductive members 153 located between the third conductive member 151 and the fourth conductive member 152, the third conductive member 151 is connected between the radiation pattern and a first connection branch 14 adjacent to the radiation pattern. The fourth conductive member 152 is connected between the ground pattern and a first connection branch 14 adjacent to the ground pattern, the plurality of fifth conductive members 153 are connected between two adjacent first connection branches 14, and the two adjacent conductive structures 15 are respectively arranged at the two ends of the same first connection branch 14.

[0128] In some embodiments, Figure 7 As shown, the connection assembly 1 includes a plurality of first connection branches 14. The plurality of first connection branches 14 are arranged on the plurality of third arrangement surfaces 53 in a one-to-one correspondence, and the radiation pattern is electrically connected to the ground pattern through the plurality of first connection branches 14.

[0129] In this embodiment, when the connecting component 1 transmits guided electromagnetic waves between the radiating part 2 and the grounding part 4, the guided electromagnetic waves will pass through multiple first connecting branches 14 in sequence. The multiple first connecting branches 14 are respectively arranged on the third arrangement surface 53, which can effectively improve the insertion loss of the connecting component 1 and avoid mutual interference between the radiating part 2 and the grounding part 4 at the connection position of the connecting component 1.

[0130] In other embodiments, Fig. 9 and Fig.11As shown, the operating frequency band of the ultra-wideband antenna in this embodiment is 5.58 GHz-6.1 GHz. Since the ultra-wideband antenna in this embodiment does not have a connecting component 1, the electric potential of the first area and the second area is completely consistent, and the connecting position of the first area and the second area cancels each other. When the connecting component 1 does not generate a resonant current, the waveform of the second operating frequency band almost disappears.

[0131] In an optional implementation, the ultra-wideband antenna in the above embodiment can be applied to electronic devices. The electronic devices include but are not limited to smart watches, mobile phones, notebooks or vehicle-mounted terminals. The vehicle-mounted terminal is used to provide a positioning function for the vehicle.

[0132] In summary, the electronic device in this embodiment couples the radiating part 2 of the ultra-wideband antenna with the grounding part 4, and simultaneously sets the first feeding point 21 and the second feeding point 22 on the radiating part 2, and sets the first feeding point 21 and the second feeding point 22 corresponding to the two first extension sections 231. As a result, the guided electromagnetic waves fed by the feeding part 3 to the radiating part 2 are mutually offset in the arrangement direction of the first feeding point 21 and the second feeding point 22, thereby generating guided electromagnetic waves conducted along the extension direction of the first side 23. Furthermore, by controlling the length of the first side 23, the ultra-wideband antenna radiates electromagnetic waves. The operating frequency and the operating bandwidth are improved. On the other hand, by simultaneously using the first feeding point 21 and the second feeding point 22 to feed the guided electromagnetic waves to the radiating part 2, the two first sides 23 can both affect the radiation of the electromagnetic waves, thereby improving the beam width of the ultra-wideband antenna and having better symmetry.

For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
