[0025] The following is a detailed description of the rubber stick antenna provided in the embodiment of the present application through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0026] like Figure 1 to Figure 2 As shown, the embodiment of the present application discloses a rubber stick antenna, which is applied to 5G communication equipment. Optionally, the 5G communication equipment can be a wireless router, a camera, a radio, a smart home, etc., and the embodiment of the present application does not specifically limit this. The 5G communication equipment includes a 5G communication module.

[0027] The rubber stick antenna includes a housing 100, a substrate 200, a first radiation unit 300 and a second radiation unit 400. Optionally, the substrate 200 can be made of FR4 plate material, and of course, it can also be made of other types of plates. The embodiment of the present application does not impose specific restrictions on this. The housing 100 has a receiving cavity, and the substrate 200 is arranged in the receiving cavity of the housing 100. The first radiation unit 300 and the second radiation unit 400 are both arranged on the substrate 200, and are arranged at intervals along the length direction of the rubber stick antenna to ensure that there is a certain degree of isolation between the two to avoid mutual interference. The first radiation unit 300 and the second radiation unit 400 both include a radiator 310 and a grounding body 320 arranged at intervals. Optionally, the radiator 310 can be a copper foil structure, and of course, it can also be other metal structures. The embodiment of the present application does not impose specific restrictions on this. The radiator 310 is provided with a feeding port 311 for feeding an electrical signal, the feeding port 311 of the first radiating unit 300 is used to be electrically connected to the main antenna port or the diversity antenna port of the 5G communication module, and the feeding port 311 of the second radiating unit 400 is used to be electrically connected to the MIMO antenna port of the 5G communication module. Optionally, at least one of the first radiating unit 300 and the second radiating unit 400 is an omnidirectional antenna, which radiates electromagnetic waves 360° in both the horizontal plane and the vertical plane, and has a large coverage range.

[0028] In the embodiment of the present application, a first radiation unit 300 and a second radiation unit 400 are integrated in a housing 100 of a rubber stick antenna. When the rubber stick antenna is plugged into a 5G communication module of a 5G communication device, the first radiation unit 300 and the second radiation unit 400 are respectively plugged and matched with different antenna ports of the 5G communication module, so as to reduce the number of rubber stick antennas plugged into the 5G communication device on the basis of meeting the actual required working frequency band, thereby reducing the occupied space of the antenna in the 5G communication device. Therefore, the embodiment of the present application can solve the problem of large occupied space of the antenna in the current 5G communication device.

[0029] In addition, in the above embodiment, when the number of rubber stick antennas plugged into the 5G communication device is reduced, the utilization rate of a single rubber stick antenna can be greatly improved, and the aesthetics of the 5G communication device can be effectively improved.

[0030] Optionally, the radiator 310 and the grounding body 320 can be respectively arranged on different surfaces of the substrate 200, for example, two opposite surfaces of the substrate 200. In this case, in the direction perpendicular to the substrate 200, the orthographic projection of the radiator 310 and the orthographic projection of the grounding body 320 can be staggered; or, in other embodiments, the substrate 200 has a mounting surface 210, and the radiator 310 and the grounding body 320 are both arranged on the mounting surface 210, that is, the radiator 310 and the grounding body 320 are arranged on the same surface of the substrate 200. Since the radiator 310 and the grounding body 320 are arranged at intervals, there must be a gap between the radiator 310 and the grounding body 320. At this time, when the radiator 310 is fed with an electrical signal, the radiator 310 and the grounding body 320 can be coupled to each other through the gap, so that the grounding body 320 generates a coupling current, and accordingly the grounding body 320 will radiate electromagnetic waves to increase the bandwidth of the radiator 310. That is to say, this solution widens the bandwidth of the radiator 310 by arranging the radiator 310 and the grounding body 320 on the same surface of the substrate 200 , and can save the manufacturing materials of the rubber stick antenna to reduce the cost.

[0031] In an optional embodiment, the grounding body 320 may be a continuous integral structure; or, the grounding body 320 includes a first grounding portion 321 and a second grounding portion 322 spaced apart along the width direction of the substrate 200. Specifically, the grounding bodies 320 of the first radiation unit 300 and the second radiation unit 400 include a first grounding portion 321 and a second grounding portion 322 spaced apart. There is a gap between the radiator 310 and the first grounding portion 321 and the second grounding portion 322. When the radiator 310 is fed with an electrical signal, the first grounding portion 321 and the second grounding portion 322 are coupled to the radiator 310, so that coupling currents are generated inside the first grounding portion 321 and inside the second grounding portion 322. At this time, both of them radiate electromagnetic waves to their surroundings, thereby improving the uniformity of electromagnetic energy distribution around the radiator 310, and the distribution range of the electromagnetic waves is larger.

[0032] Optionally, the rubber stick antenna further includes a first feeder 500 and a second feeder 600, wherein the first end of the first feeder 500 is electrically connected to the feeding port 311 of the first radiation unit 300, that is, the first feeder 500 is used to transmit electrical signals to the first radiation unit 300, and a portion of the first feeder 500 (such as the second connecting section 520 of the first feeder 500 described later) is located between the first grounding portion 321 and the second grounding portion 322 of the first radiation unit 300, so as to facilitate the connection of the first end of the first feeder 500 with the first radiation unit 300, and And it facilitates the wiring of the first feeder 500; the first end of the second feeder 600 is electrically connected to the feeding port 311 of the second radiation unit 400, that is, the second feeder 600 is used to transmit electrical signals to the second radiation unit 400, and a portion of the second feeder 600 (such as the second connecting section 520 of the second feeder 600 described later) is located between the first grounding portion 321 and the second grounding portion 322 of the second radiation unit 400, so as to facilitate the connection of the first end of the second feeder 600 with the second radiation unit 400 and facilitate the wiring of the second feeder 600.

[0033] In an optional embodiment, the first radiating portion 312 may also be a rectangular structure, etc., which may be arranged on the side of the grounding body 320 of the first radiating unit 300 away from the second radiating unit 400; or, the radiating body 310 of the first radiating unit 300 includes a first radiating portion 312, and the first radiating portion 312 is a long strip structure, and the first radiating portion 312 extends along the length direction of the rubber stick antenna, and at least part of the first radiating portion 312 is arranged at intervals between the first grounding portion 321 and the second grounding portion 322 of the first radiating unit 300, and there is a gap between the first radiating portion 312 and the first grounding portion 321 and the second grounding portion 322 of the first radiating unit 300. In this solution, the space on both sides of the first radiating portion 312 of the long strip structure is relatively large, so the size of the first grounding portion 321 and the second grounding portion 322 can be increased, thereby widening the bandwidth of the radiator 310; and the gap between the first radiating portion 312 and the first grounding portion 321 and the second grounding portion 322 on both sides thereof is relatively long, which can improve the coupling performance, thereby improving the radiation performance of the grounding body 320 of the first radiating unit 300; in addition, adopting this setting method can improve the structural compactness of the radiator 310 and the grounding body 320 of the first radiating unit 300 to save space.

[0034] It should be noted that, in the above embodiment, the first radiating portion 312 is at least partially spaced between the first grounding portion 321 and the second grounding portion 322 of the first radiating unit 300, which is mainly used to broaden the bandwidth of the low-frequency band of the first radiating unit 300, where the low-frequency band is 703 to 960 MHz.

When a coupling current is generated inside the grounding body 320 of the first radiation unit 300, the first grounding portion 321 and the second grounding portion 322 of this structure can extend the current path inside it, so as to reduce the size of the grounding body 320 of the first radiation unit 300 without increasing the size of the substrate 200 and effectively widening the bandwidth of the first radiation unit 300. Of course, at least one of the first grounding portion 321 and the second grounding portion 322 of the first radiation unit 300 can also be a rectangular structure, etc.

Since the space on the side of the first radiating portion 312 away from the second radiating unit 400 is large, the size of the second radiating portion 313 can be increased according to actual needs, thereby widening the operating frequency of the first radiating unit 300 to generate frequency doubling, thereby forming a medium and high frequency band, that is, the second radiating portion 313 is used to radiate electromagnetic waves in the medium and high frequency bands, so as to further widen the bandwidth of the first radiating unit 300.

[0038] In an optional embodiment, an opening 313a is provided at one end of the second radiating portion 313 close to the first radiating portion 312 to extend the circuit path inside the second radiating portion 313, thereby widening the high-frequency bandwidth. Of course, the opening 313a may also be omitted.

[0039] Optionally, the opening 313a extends along the width direction of the substrate 200, that is, the width of the opening 313a extends along the length direction of the substrate 200. In this case, the width of the opening 313a can be flexibly selected according to actual needs without affecting the connection between the second radiating portion 313 and the first radiating portion 312, thereby widening the high-frequency bandwidth. Of course, the opening 313a can also be directed toward the grounding body 320, in which case the opening 313a extends along the length direction of the substrate 200.
