The adjacent two first connecting vibrator arms 21 are electrically connected by the connecting member 3.
It is understood that the connection member 3 can transmit the electricity of the feeding device or the feeding network to the plurality of first pendulum parts 2 of the pendulum group, so that the plurality of first pendulum parts 2 can collectively function as a radiation structure to enhance the radiation performance of the antenna. During feeding, the antenna can generate resonance of a high radiation frequency band and resonance of a low radiation frequency band, so that the antenna can simultaneously realize the functions of high-frequency strong orientation and low-frequency weak orientation.

The antenna of the embodiment can meet the coverage of commonly used 2.4GHz and 5.8GHz frequency bands, and has better directionality. Further, the first low-frequency oscillator arm 23 and the first high-frequency oscillator arm 22 are both connected to the first connecting oscillator arm 21, and the antenna size can be reduced.
Specifically, in the present embodiment, the vibrator group includes two first vibrator parts 2 arranged at intervals, and when only one vibrator group is arranged on the surface of the substrate 1, the vibrator group can be arranged on any surface of the substrate 1 according to actual requirements without being particularly limited.
In some specific embodiments, as shown in fig. 4, the distance between the two first low-frequency vibrator arms 23 on the first connecting vibrator arm 21 is smaller than the distance between the two first high-frequency vibrator arms 22, and the first high-frequency vibrator arm 22 includes a first extension, a second extension and a third extension, the width of the first extension is smaller than that of the third extension, and the width of the second extension is gradually larger in a direction away from the first extension.
In some embodiments, as shown in fig. 3 to 6, the vibrator group further includes a plurality of second vibrator portions 4 distributed along the length direction of the substrate 1; the second oscillator part 4 comprises a second connecting oscillator arm 41, a second high-frequency oscillator arm 42 and a second low-frequency oscillator arm 43, the second connecting oscillator arm 41 extends along the width direction of the substrate 1, two ends of the second connecting oscillator arm 41 are respectively connected with one second low-frequency oscillator arm 43 and one second high-frequency oscillator arm 42, the second low-frequency oscillator arm 43 and the second high-frequency oscillator arm 42 extend from the second connecting oscillator arm 41 to the same direction in the length direction of the substrate 1, and two adjacent second connecting oscillator arms 41 are electrically connected through the connecting piece 3; the first pendulum part 2 and the second pendulum part 4 are respectively provided on both sides of the substrate 1, and the first high-frequency pendulum arm 22 and the first low-frequency pendulum arm 23 are oriented in opposite directions to the second high-frequency pendulum arm 42 and the second low-frequency pendulum arm 43.
It can be understood that, by providing the plurality of first transducer parts 2 and the plurality of second transducer parts 4 on the two sides of the substrate 1, the receiving and transmitting effects of the antenna on the signal can be enhanced, and the stability of signal transmission can be improved, so that the reliability of the antenna can be improved.
In some embodiments, as shown in fig. 3 to 6, the projections of the first and second connection vibrator arms 21 and 41 on the substrate 1 coincide, and the first and second vibrator parts 2 and 4 are symmetrically disposed about the first connection vibrator arm 21.
It can be understood that, with the above-described arrangement, the first vibrator part 2 can be prevented from being affected by the second vibrator part 4 during operation, so that mutual interference between the first vibrator part 2 and the second vibrator part 4 during operation is avoided, and stability of receiving and transmitting signals by the antenna is improved.
In some embodiments, as shown in fig. 1 and fig. 2, the antenna further includes a coaxial line 5, the coaxial line 5 has an inner core and an outer conductor 51 sleeved on the inner core, an end of the coaxial line 5 is inserted into the substrate 1, and the inner core and the outer conductor 51 are electrically connected to one of the transducer groups, respectively.
It will be appreciated that since the sets of oscillators are provided on both oppositely disposed sides of the substrate 1, the connector 3 needs to feed both sets of oscillators simultaneously. The coaxial line 5 penetrating the substrate 1 includes an outer conductor 51 of an inner core, so that the outer conductor 51 can be electrically connected with the vibrator group on one side of the substrate 1, and the inner core can penetrate the substrate 1 and is electrically connected with the vibrator group on the other side of the substrate 1, thereby remarkably simplifying the feed structure of the antenna, optimizing the radiation structure of the antenna, better realizing single-feed dual-frequency radiation of the antenna, and enabling the antenna directional pattern of low frequency to have better performance and standing wave bandwidth.
Specifically, in the present embodiment, as shown in fig. 2, the outer conductor 51 is electrically connected to the microstrip line through a pad 52 that is fitted over the outer conductor 51.

It can be understood that, after the limiting part 7 is arranged, the vertical distance between the coaxial line 5 and the base material can be increased, the problem of contact interference between the coaxial line 5 and the first vibrator part 2 is prevented, the limiting effect can be achieved on the coaxial line 5 in the axial direction and the direction perpendicular to the side surface of the substrate 1, the coaxial line 5 is fixed relative to the substrate 1, the influence of signals on harmonic waves during transmission can be effectively improved, and the stability of the signals is further improved.
Specifically, the stopper 7 can be made of an insulating material such as foam or plastic.
In some embodiments, the oscillator frequencies of the first connected oscillator arm 21 and the first high frequency oscillator arm 22 are the same, and the frequencies of the second connected oscillator arm 41 and the second high frequency oscillator arm 42 are the same. It can be understood that, with the above arrangement, the first connecting vibrator arm 21 can be made to function also as the first high-frequency vibrator arm 22, improving the utilization rate of the first connecting vibrator arm 21.
In some embodiments, the lengths of the first connecting vibrator arm 21 and the first low frequency vibrator arm 23 and 1/4-3/4 being the low frequency resonance wavelength; the lengths of the first connecting vibrator arm 21 and the first high- frequency vibrator arm 22 and 1/4-3/4 which is the high-frequency resonance wavelength; the lengths of the second connecting vibrator arm 41 and the second low- frequency vibrator arm 43 and 1/4-3/4 which are low-frequency resonance wavelengths; the lengths of the second connecting vibrator arm 41 and the second high- frequency vibrator arm 42 and 1/4-3/4 which is the high-frequency resonance wavelength.
It can be understood that, by adjusting the lengths of the first connecting vibrator arm 21 and the first low-frequency vibrator arm 23, the lengths of the first connecting vibrator arm 21 and the first high-frequency vibrator arm 22, and the lengths of the second connecting vibrator arm 41 and the second low-frequency vibrator arm 43, and the lengths of the second connecting vibrator arm 41 and the second high-frequency vibrator arm 42, the radiation frequency band range of the antenna in the actual use process can be adjusted, for example, as shown in fig. 7-10, in the present embodiment, the antenna can be operated in the low-frequency signal range of 2.39GHz to 2.65GHz and the high-frequency signal range of 5.53GHz to 6GHz by the above arrangement, so as to ensure that the antenna can realize the coverage of 2.4GHz and 5.8GHz bands.
In some embodiments, as shown in fig. 1, 3 and 4, the connecting part 3 includes a microstrip line, and both ends of the microstrip line are electrically connected to two adjacent first connecting vibrator arms 21, respectively.
It can be understood that, after the microstrip line is provided, the microstrip line is only electrically connected to the feeding device, so that the feeding to the two first oscillator parts 2 and the feeding to the two second oscillator parts 4 can be realized simultaneously, thereby further optimizing the feeding structure of the antenna.
In some specific embodiments, as shown in fig. 1, 3 and 4, in the width direction of the substrate 1, the microstrip line is located between two adjacent first low-frequency oscillator arms 23 and between two adjacent second low-frequency oscillator arms 43, so that the radiation structure of the first low-frequency oscillator arm 23 and the first high-frequency oscillator arm 22 connected to the first connecting oscillator arm 21 and the radiation structure of the second low-frequency oscillator arm 43 and the second high-frequency oscillator arm 42 connected to the second connecting oscillator arm 41 can be formed, and the impedance of the dual-frequency antenna can be conveniently adjusted to increase and adjust the impedance of the dual-frequency antenna, so as to increase the bandwidth of the radiation frequency band of the first oscillator part 2 and the second oscillator part 4, and make the performance of the antenna more stable.
In some embodiments, as shown in fig. 1, 3 and 4, the antenna further includes a plurality of reflectors 6, each reflector 6 being disposed corresponding to one of the first pendulum parts 2, the reflectors 6 being used to reinforce the signal of the first pendulum part 2.
It is understood that the reflector 6 can strengthen the signal strength in the predetermined direction while weakening the signal strength in the opposite direction, and thus, after the reflector 6 is disposed, it can strengthen the first low frequency dipole arm 23 and the first high frequency dipole arm 22 of the first dipole part 2, thereby improving the omni-directionality of the antenna.
In some embodiments, as shown in fig. 4, the reflector 6 extends along the length direction of the substrate 1, and the length of the reflector 6 is greater than the arm length of the first high-frequency vibrator arm 22 and less than the arm length of the first low-frequency vibrator arm 23.
It can be understood that, when the length of the reflector 6 is greater than the arm length of the first high-frequency oscillator arm 22, the single-side strengthening effect on the high-frequency oscillator signal can be achieved, so as to realize the direction of the high-frequency signal; meanwhile, the length of the reflector 6 is smaller than the arm length of the first low-frequency oscillator arm 23, so that the same direction of low-frequency signals can be strengthened, and certain omni-directionality can still be realized.
In some specific embodiments, at least one of the two oppositely disposed side surfaces of the substrate 1 is provided with the reflector 6, that is, no matter which side surface of the substrate 1 is provided with the vibrator set, the reflector 6 can be disposed on the substrate 1 according to actual requirements, so as to achieve the effect of improving the omni-directionality of the antenna.

The mounting member 9 is rotatably connected to the body 8. The antenna is arranged in the mounting part 9, and the connecting part 3 of the antenna is connected with the body 8.
