For example, achieving 360° full coverage, low non-circularity, and the elevation angle are very important parameters for vertical polarization omnidirectional antennas.

[0003] However, due to the need to form a MIMO antenna form for some applications, the size of the existing 5G full-band omnidirectional antenna is required to be relatively large. Moreover, when the existing 5G full-band omnidirectional antenna meets the large bandwidth, its non-circularity and elevation angle are generally too large. Summary of the Invention

[0040] The present disclosure relates to a 5G full-band omnidirectional antenna device. In one embodiment, the 5G full-band omnidirectional antenna device includes a bottom plate, a dipole antenna assembly, and two metal capacitor plates; the two metal capacitor plates are arranged in parallel with each other, and the two metal capacitor plates are respectively connected to two ends of the bottom plate, and the metal capacitor plates are used for receiving and transmitting antenna signals; the dipole antenna assembly includes a first dipole antenna structure and a second dipole antenna structure, the first dipole antenna structure and the second dipole antenna structure are both arranged on the bottom plate, the first dipole antenna structure and the second dipole antenna structure are arranged opposite to each other, so that a feeding point is formed at the relative position of the first dipole antenna structure and the second dipole antenna structure, and the first dipole antenna structure and the second dipole antenna structure are respectively electrically connected to one of the metal capacitor plates; in a direction perpendicular to the two metal capacitor plates, the total length between the first dipole antenna structure and the second dipole antenna structure is a first distance; in a direction parallel to the two metal capacitor plates, the maximum length of the first dipole antenna structure and the second dipole antenna structure is a second distance; in a direction perpendicular to the bottom plate, the maximum height of the first dipole antenna structure and the second dipole antenna structure is a third distance; wherein, the sum of the first distance, the second distance, and the third distance is greater than or equal to 150 mm.

The limitation of the second distance makes the antenna have a low non-circularity, and the limitation of the first distance can reduce the lobes of the pattern in the high-frequency range, so that the maximum elevation angle of the antenna is reduced.

[0041] Please refer to Figure 1 , which is a schematic structural diagram of a 5G full-band omnidirectional antenna device according to an embodiment of the present disclosure.

[0042] The 5G full-band omnidirectional antenna device 10 of an embodiment includes a bottom plate 100, a dipole antenna assembly 300, and two metal capacitor plates 200. The two metal capacitor plates 200 are arranged in parallel with each other, and the two metal capacitor plates 200 are respectively connected to both ends of the bottom plate 100. The metal capacitor plates 200 are used for receiving and transmitting antenna signals. The dipole antenna assembly 300 includes a first dipole antenna structure 310 and a second dipole antenna structure 320. The first dipole antenna structure 310 and the second dipole antenna structure 320 are both arranged on the bottom plate 100. The first dipole antenna structure 310 and the second dipole antenna structure 320 are arranged opposite to each other, so that a feeding point is formed at the relative position between the first dipole antenna structure 310 and the second dipole antenna structure 320. The first dipole antenna structure 310 and the second dipole antenna structure 320 are respectively electrically connected to one of the metal capacitor plates 200. In the direction perpendicular to the two metal capacitor plates 200, the total length between the first dipole antenna structure 310 and the second dipole antenna structure 320 is a first distance. In the direction parallel to the two metal capacitor plates 200, the maximum length of the first dipole antenna structure 310 and the second dipole antenna structure 320 is a second distance. In the direction perpendicular to the bottom plate 100, the maximum height of the first dipole antenna structure 310 and the second dipole antenna structure 320 is a third distance. Wherein, the sum of the first distance, the second distance, and the third distance is greater than or equal to 150 mm.

[0043] In this embodiment, by adding metal capacitor plates 200 to both ends of the bottom plate 100, it is convenient to introduce low-frequency resonance points. The first distance, the second distance, and the third distance together determine the low-frequency resonance points. Moreover, by limiting the sum of the first distance, the second distance, and the third distance, the antenna pattern in the high-frequency range can also be adjusted. The limitation of the second distance makes the antenna have low non-circularity, and the limitation of the first distance can reduce the pattern lobes in the high-frequency range, thereby reducing the maximum elevation angle of the antenna.

[0044] Wherein, the low-frequency band range is 600 - 960 MHz, and the high-frequency band range is 1400 - 5000 MHz.

[0045] In another embodiment, the feeding point of the first dipole antenna structure 310 and the second dipole antenna structure 320 is the feeding gap between the two.

[0046] In one embodiment, the first distance is less than or equal to 110 mm. In this embodiment, the first distance is the total length between the first dipole antenna structure 310 and the second dipole antenna structure 320, that is, the first distance is the distance between the two metal capacitor plates 200, or the first distance is the longitudinal total length of the first dipole antenna structure 310 and the second dipole antenna structure 320. The direction of the first distance is perpendicular to the direction of the two metal capacitor plates 200. The magnitude of the first distance determines the maximum elevation angle of the antenna pattern of the first dipole antenna structure 310 and the second dipole antenna structure 320 in the high-frequency range. Specifically, in the high-frequency band range of 1400 - 5000 MHz, the maximum radiation direction elevation angle of the antenna pattern is less than 10°. Thus, by limiting the length of the first distance to not exceed 110 mm, the lobing of the antenna pattern in the high-frequency band range of 1400 - 5000 MHz can be effectively avoided, thereby limiting the elevation angle of the antenna within 10°.

[0047] In another embodiment, the first distance is from 68 mm to 85 mm.

[0048] In one embodiment, the second distance is less than or equal to 110 mm. In this embodiment, the second distance is the maximum side length of the first dipole antenna structure 310 and the second dipole antenna structure 320, that is, the second distance is the maximum side spacing between the first dipole antenna structure 310 and the second dipole antenna structure 320, or the second distance is the maximum lateral length of the first dipole antenna structure 310 and the second dipole antenna structure 320. The second distance is used to reflect the maximum width of the first dipole antenna structure 310 and the second dipole antenna structure 320. By restricting the second distance, a low level of circularity of the antenna pattern in the high-frequency band range of 1400 - 5000 MHz is ensured.

[0049] In another embodiment, the second distance is from 45 mm to 63 mm.

[0050] In one embodiment, please refer to Figure 1, at least one of the first dipole antenna structure 310 and the second dipole antenna structure 320 is provided with a broken-edge slot 302, and the opening of the broken-edge slot 302 is used to break the edge of the corresponding antenna structure. In this embodiment, the broken-edge slot 302 is provided on at least one of the first dipole antenna structure 310 and the second dipole antenna structure 320. The broken-edge slot 302 corresponds to the edge in the first dipole antenna structure 310 and the second dipole antenna structure 320. The opening of the broken-edge slot 302 is opposite to the corresponding edge in the first dipole antenna structure 310 and the second dipole antenna structure 320. Specifically, the opening of the broken-edge slot 302 breaks the corresponding edge in the first dipole antenna structure 310 and the second dipole antenna structure 320. For high frequencies, the first dipole antenna structure 310 and the second dipole antenna structure 320 have a large metal surface on the bottom plate 100, and the 3D pattern is prone to pits in the direction perpendicular to the bottom plate 100. By adding the broken-edge slot 302, high-frequency electromagnetic waves can pass through the bottom plate 100 to eliminate the pits. Moreover, since most of the current moves along the edges of the first dipole antenna structure 310 and the second dipole antenna structure 320, by setting the broken-edge slot 302 that breaks at the edge, the high-frequency non-circularity performance of the antenna can be improved, that is, the high-frequency non-circularity of the antenna can be reduced.

[0051] In another embodiment, the broken-edge slot 302 is provided on the side of the first dipole antenna structure 310.

[0052] In another embodiment, the broken-edge slot 302 is provided on the side of the second dipole antenna structure 320.

[0053] In another embodiment, the side of the first dipole antenna structure 310 and the side of the first dipole antenna structure 310 are both provided with the broken-edge slot 302.

[0054] In another embodiment, the distance between the broken-edge slot 302 and the feeding point is 6 mm to 38 mm.

[0055] In another embodiment, the distance between the broken-edge slot 302 and the feeding point is 25 mm.

[0056] In another embodiment, the length of the broken-edge slot 302 is 15 mm to 55 mm. The length of the broken-edge slot 302 is related to the low-frequency resonance frequency. Since the broken-edge slot 302 is used to break the edge of the dipole antenna structure, and most of the current moves along the edge of the dipole antenna structure, by controlling the length of the broken-edge slot 302, it is convenient to adjust the length of the low-frequency current path, thereby adjusting the low-frequency resonance frequency. Moreover, the length of the broken-edge slot 302 is also used to improve the non-circularity of the high-frequency H-plane and the low-frequency standing wave of the antenna.

[0057] In another embodiment, the length of the edge-breaking groove 302 is 35 mm.

[0058] In one embodiment, refer to Figure 1 , the dipole antenna assembly 300 further includes at least one first stub 330, the first stub 330 is electrically connected to at least one of the first dipole antenna structure 310 and the second dipole antenna structure 320, and the first stub 330 is perpendicular to the bottom plate 100. In this embodiment, the first stub 330 is disposed on the first dipole antenna structure 310 and / or the second dipole antenna structure 320, and the first stub 330 is also perpendicular to the bottom plate 100, so that the first stub 330 is perpendicular to both the first dipole antenna structure 310 and the second dipole antenna structure 320 laid flat on the bottom plate 100, so that the first stub 330 radiates signals in a direction perpendicular to the bottom plate 100. Since the first dipole antenna structure 310 and the second dipole antenna structure 320 have a large metal surface in the plane of the bottom plate 100, the 3D radiation pattern in the high-frequency band of this antenna is likely to have a depression in the direction perpendicular to the bottom plate 100. By introducing the first stub 330 in this direction, the gain in the high-frequency band in this direction can be increased, thereby reducing the high-frequency non-circularity. The corresponding antenna S11 gain is as Figure 2 shown.

[0059] In another embodiment, one first stub 330 is respectively disposed on the first dipole antenna structure 310 and the second dipole antenna structure 320 to further reduce the high-frequency non-circularity.

[0060] In one embodiment, refer to Figure 3 , the dipole antenna assembly 300 further includes at least one second stub 340, the second stub 340 is electrically connected to at least one of the first dipole antenna structure 310 and the second dipole antenna structure 320, and the second stub 340 is parallel to the metal capacitor plate 200. In this embodiment, the second stub 340 is disposed on the first dipole antenna structure 310 and / or the second dipole antenna structure 320, and the second stub 340 is also parallel to the bottom plate 100, that is, the second stub 340 is also laid flat on the bottom plate 100, so that the second stub 340, the first dipole antenna structure 310 and the second dipole antenna structure 320 on the bottom plate 100 are all laid flat on the bottom plate 100, so that the second stub 340 radiates signals in a direction parallel to the bottom plate 100, which is convenient for the second stub 340 to optimize the non-circularity of the H-plane pattern and also has the effect of adjusting the standing wave of this shaped antenna.

[0061] In another embodiment, the second stub 340 is parallel to the metal capacitor plate 200.

[0062] In another embodiment, the broken-edge groove 302, the first stub 330, and the second stub 340 together improve the non-circularity of the H-plane radiation pattern of the antenna over the entire frequency band, that is, they have low non-circularity, and avoid lobes in the E-plane radiation pattern of the antenna over the entire frequency band, thereby improving the antenna standing wave. For details, see the appendix Figures 4 to 17 。

[0063] In one of the embodiments, please refer to Figure 18 , the dipole antenna assembly 300 further includes at least one third stub 350, the third stub 350 is electrically connected to at least one of the first dipole antenna structure 310 and the second dipole antenna structure 320, the third stub 350 is parallel to the bottom plate 100, and the third stub 350 corresponds to the feed point. In this embodiment, the third stub 350 is disposed on the first dipole antenna structure 310 and / or the second dipole antenna structure 320, and the third stub 350 is also parallel to the bottom plate 100, that is, the third stub 350 is also laid flat on the bottom plate 100, so that the third stub 350, the first dipole antenna structure 310 on the bottom plate 100, and the second dipole antenna structure 320 are all laid flat on the bottom plate 100, so that the third stub 350 radiates signals in a direction parallel to the bottom plate 100. Moreover, the third stub 350 corresponds to the feed point, and the third stub 350 serves as a feed improvement stub between the first dipole antenna structure 310 and the second dipole antenna structure 320, so that the stubs near the feed point play a role in optimizing the antenna standing wave.

[0064] In another embodiment, the first dipole antenna structure 310 and the second dipole antenna structure 320 are both provided with a third stub 350, and the third stub 350 on the first dipole antenna structure 310 corresponds to the feed groove of the second dipole antenna structure 320, that is, at least a part of the third stub 350 on the first dipole antenna structure 310 is located in the feed groove of the second dipole antenna structure 320, where the feed groove is a groove formed between two third stubs 350 of the second dipole antenna structure 320 to improve the effect of the feed point in optimizing the antenna standing wave.

[0065] In another embodiment, one third stub 350 is disposed on each side of the second dipole antenna structure 320.

[0066] In another embodiment, one side of the first dipole antenna structure 310 close to the feeding point is arc-shaped, and a plurality of third branches 350 are evenly distributed on the first dipole antenna structure 310 and close to the feeding point.

[0067] In one embodiment, a 5G omnidirectional antenna includes the 5G full-band omnidirectional antenna device described in any of the above embodiments. In this embodiment, the 5G full-band omnidirectional antenna device includes a bottom plate, a dipole antenna assembly, and two metal capacitor plates; the two metal capacitor plates are arranged in parallel with each other, and the two metal capacitor plates are respectively connected to both ends of the bottom plate, and the metal capacitor plates are used for receiving and transmitting antenna signals; the dipole antenna assembly includes a first dipole antenna structure and a second dipole antenna structure, the first dipole antenna structure and the second dipole antenna structure are both arranged on the bottom plate, the first dipole antenna structure and the second dipole antenna structure are arranged opposite to each other, so that a feeding point is formed at the relative position between the first dipole antenna structure and the second dipole antenna structure, and the first dipole antenna structure and the second dipole antenna structure are respectively electrically connected to one of the metal capacitor plates; in the direction perpendicular to the two metal capacitor plates, the total length between the first dipole antenna structure and the second dipole antenna structure is a first distance; in the direction parallel to the two metal capacitor plates, the maximum length of the first dipole antenna structure and the second dipole antenna structure is a second distance; in the direction perpendicular to the bottom plate, the maximum height of the first dipole antenna structure and the second dipole antenna structure is a third distance; wherein, the sum of the first distance, the second distance, and the third distance is greater than or equal to 150 mm.
