Description
Technical Field
[0001] This invention relates to the field of communication technology, and more particularly to an antenna and a remote control. Background Technology
[0002] Antennas are typically used to transmit and receive resonant waves in different frequency bands. With the rapid development of wireless communication and the demand for various data services, antenna design is mainly moving towards miniaturization, multi-band, and wide bandwidth. Existing antennas are less able to meet the requirements for receiving and transmitting multi-band resonant waves.
[0003] Therefore, there is an urgent need for an antenna and remote controller that can cover the commonly used 2.4GHz and 5.8GHz frequency bands and has good directionality. Summary of the Invention
[0004] The first objective of this invention is to provide an antenna that can cover the commonly used 2.4GHz and 5.8GHz frequency bands and has good directivity.
[0005] The second objective of this invention is to provide a remote control that facilitates the control of other devices, reduces the negative impact of device operation on communication, and ensures reliable communication during device operation.
[0006] To achieve the above-mentioned technical effects, the technical solution of the present invention is as follows:
[0007] An antenna includes: a substrate; a vibrator group, wherein at least one of the oppositely disposed sides of the substrate is provided with the vibrator group, the vibrator group including a plurality of first vibrator portions distributed along the length direction of the substrate; each first vibrator portion includes a first connecting vibrator arm, a first high-frequency vibrator arm, and a first low-frequency vibrator arm, the first connecting vibrator arm extending along the width direction of the substrate, and each end of the first connecting vibrator arm being respectively connected to a first low-frequency vibrator arm and a first high-frequency vibrator arm, the first low-frequency vibrator arm and the first high-frequency vibrator arm extending in the same direction along the length direction of the substrate from the first connecting vibrator arm; and a connector, wherein two adjacent first connecting vibrator arms are electrically connected through the connector.
[0008] Furthermore, the oscillator assembly further includes a plurality of second oscillator portions distributed along the length direction of the substrate; the second oscillator portion includes a second connecting oscillator arm, a second high-frequency oscillator arm, and a second low-frequency oscillator arm, the second connecting oscillator arm extending along the width direction of the substrate, and a second low-frequency oscillator arm and a second high-frequency oscillator arm respectively connected to each end of the second connecting oscillator arm, the second low-frequency oscillator arm and the second high-frequency oscillator arm extending in the same direction along the length direction of the substrate by the second connecting oscillator arm, and two adjacent second connecting oscillator arms being electrically connected through the connector; the first oscillator portion and the second oscillator portion are respectively disposed on both sides of the substrate, and the first high-frequency oscillator arm and the first low-frequency oscillator arm are oriented in the opposite direction to the second high-frequency oscillator arm and the second low-frequency oscillator arm.
[0009] Furthermore, the projections of the first connecting oscillator arm and the second connecting oscillator arm on the substrate coincide, and the first oscillator portion and the second oscillator portion are symmetrically arranged about the first connecting oscillator arm.
[0010] Furthermore, the antenna also includes a coaxial line having an inner core and an outer conductor sleeved on the inner core, with the end of the coaxial line passing through the substrate, and the inner core and the outer conductor being electrically connected to one of the oscillator groups, respectively.
[0011] Furthermore, the first connecting vibrating arm and the first high-frequency vibrating arm have the same frequency, and the second connecting vibrating arm and the second high-frequency vibrating arm have the same frequency.
[0012] Furthermore, the sum of the lengths of the first connecting oscillator arm and the first low-frequency oscillator arm is 1 / 4 to 3 / 4 of the low-frequency resonant wavelength; the sum of the lengths of the first connecting oscillator arm and the first high-frequency oscillator arm is 1 / 4 to 3 / 4 of the high-frequency resonant wavelength; the sum of the lengths of the second connecting oscillator arm and the second low-frequency oscillator arm is 1 / 4 to 3 / 4 of the low-frequency resonant wavelength; and the sum of the lengths of the second connecting oscillator arm and the second high-frequency oscillator arm is 1 / 4 to 3 / 4 of the high-frequency resonant wavelength.
[0013] Furthermore, the connector includes a microstrip line, the two ends of which are electrically connected to two adjacent first connecting oscillator arms, respectively.
[0014] Furthermore, the antenna also includes a plurality of reflectors, each of which is configured corresponding to one of the first oscillator sections, and the reflectors are used to amplify the signal of the first oscillator section.
[0015] Furthermore, the reflector extends along the length of the substrate, and the length of the reflector is greater than the arm length of the first high-frequency oscillator arm and less than the arm length of the first low-frequency oscillator arm.
[0016] A remote controller includes: a body; a mounting component rotatably connected to the body; and an antenna as described above, the antenna being disposed within the mounting component, and the antenna's connector being connected to the body.
[0017] One beneficial effect of this invention is that the connector can deliver electricity from the feeding device or feeding network to multiple first vibrator sections of the vibrator group, allowing the multiple first vibrator sections to work together as a radiating structure to enhance the antenna's radiation performance. During feeding, the antenna can generate resonance in both the high-radiation frequency band and the low-radiation frequency band, thus enabling the antenna to simultaneously achieve strong high-frequency directional and weak low-frequency directional functions. Specifically, when the first high-frequency vibrator arm and the first connecting vibrator arm of the multiple first vibrator sections are both operational, and the first low-frequency vibrator arm is both deactivated, the vibrator group can receive and transmit high-frequency signals. In this embodiment, the antenna can operate in the high-frequency signal range of 5.53 GHz to 6 GHz. When at least one first high-frequency vibrator arm of a first vibrator section is deactivated, while the first connecting vibrator arm, the first low-frequency vibrator arm, and other first vibrator sections remain operational, the vibrator group can receive and transmit low-frequency signals. In this embodiment, the antenna can operate in the low-frequency signal range of 2.39 GHz to 2.65 GHz. This allows the antenna in this embodiment to cover the commonly used 2.4GHz and 5.8GHz frequency bands and has good directivity.
[0018] Another beneficial effect of the present invention is that, according to the embodiments of the present invention, the remote controller, having the antenna described above, can meet the coverage of the commonly used 2.4GHz and 5.8GHz frequency bands and has good directionality, thereby facilitating the control of other devices through the remote controller, reducing the negative impact of device operation on communication, and ensuring reliable communication during device operation.

In the description of the invention, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are only used for descriptive distinction and have no special meaning.
[0036] The following is for reference. Figures 1-10 The specific structure of the antenna in an embodiment of the present invention is described.
[0037] like Figures 1-6 As shown, Figure 1 An antenna is disclosed, comprising a substrate 1, a vibrator assembly, and a connector 3. At least one of the oppositely positioned sides of the substrate 1 is provided with a vibrator assembly, which includes a plurality of first vibrator portions 2 distributed along the length direction of the substrate 1. Each first vibrator portion 2 includes a first connecting vibrator arm 21, a first high-frequency vibrator arm 22, and a first low-frequency vibrator arm 23. The first connecting vibrator arm 21 extends along the width direction of the substrate 1, and each end of the first connecting vibrator arm 21 is connected to a first low-frequency vibrator arm 23 and a first high-frequency vibrator arm 22, respectively. The first low-frequency vibrator arm 23 and the first high-frequency vibrator arm 22 extend in the same direction along the length direction of the substrate 1 from the first connecting vibrator arm 21. Adjacent first connecting vibrator arms 21 are electrically connected via the connector 3.
[0038] Understandably, the connector 3 can deliver electricity from the feeding device or feeding network to multiple first vibrator sections 2 of the vibrator group, enabling the multiple first vibrator sections 2 to work together as a radiating structure to enhance the antenna's radiation performance. During feeding, the antenna can generate resonance in both the high-radiation frequency band and the low-radiation frequency band, thus enabling the antenna to simultaneously achieve strong high-frequency directional and weak low-frequency directional functions. Specifically, when the first high-frequency vibrating arms 22 and the first connecting vibrating arms 21 of the multiple first vibrating elements 2 are all working, and the first low-frequency vibrating arms 23 are all stopped working, the vibrating element group can receive and transmit high-frequency signals. In this embodiment, the antenna can operate in the high-frequency signal range of 5.53 GHz to 6 GHz. When at least one of the first high-frequency vibrating arms 22 of the first vibrating element 2 stops working, and the first connecting vibrating arms 21, the first low-frequency vibrating arms 23, and the other first vibrating elements 2 remain working, the vibrating element group can receive and transmit low-frequency signals. In this embodiment, the antenna can operate in the low-frequency signal range of 2.39 GHz to 2.65 GHz. This allows the antenna of this embodiment to meet the coverage of the commonly used 2.4 GHz and 5.8 GHz frequency bands and has good directivity. In addition, the first low-frequency vibrating arms 23 and the first high-frequency vibrating arms 22 are all connected to the first connecting vibrating arms 21, which can reduce the antenna size.
[0039] Specifically, in this embodiment, the oscillator group includes two first oscillator parts 2 that are spaced apart. When only one oscillator group is provided on the surface of the substrate 1, the oscillator group can be provided on any surface of the substrate 1 according to actual needs, without specific limitations.
[0040] In some specific embodiments, such as Figure 4 As shown, the distance between the two first low-frequency oscillator arms 23 on the first connecting oscillator arm 21 is less than the distance between the two first high-frequency oscillator arms 22. The first high-frequency oscillator arm 22 includes a first extension section, a second extension section and a third extension section. The width of the first extension section is less than the width of the third extension section, and the width of the second extension section gradually increases in the direction away from the first extension section.
[0041] In some embodiments, such as Figures 3-6As shown, the oscillator assembly also includes multiple second oscillator sections 4 distributed along the length direction of the substrate 1; the second oscillator section 4 includes 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. A second low-frequency oscillator arm 43 and a second high-frequency oscillator arm 42 are respectively connected to each end of the second connecting oscillator arm 41. The second low-frequency oscillator arm 43 and the second high-frequency oscillator arm 42 extend in the same direction along the length direction of the substrate 1 from the second connecting oscillator arm 41. Two adjacent second connecting oscillator arms 41 are electrically connected by a connector 3. The first oscillator section 2 and the second oscillator section 4 are respectively disposed on both sides of the substrate 1. The first high-frequency oscillator arm 22 and the first low-frequency oscillator arm 23 are oriented in the opposite direction to the second high-frequency oscillator arm 42 and the second low-frequency oscillator arm 43.
[0042] It is understandable that by setting multiple first oscillator sections 2 and multiple second oscillator sections 4 on both sides of the substrate 1, the antenna's signal reception and transmission effects can be enhanced, thereby improving the stability of signal transmission and thus improving the reliability of the antenna.
[0043] In some embodiments, such as Figures 3-6 As shown, the projections of the first connecting oscillator arm 21 and the second connecting oscillator arm 41 on the substrate 1 coincide, and the first oscillator part 2 and the second oscillator part 4 are symmetrically arranged about the first connecting oscillator arm 21.
[0044] It is understandable that the above structural design can prevent the first oscillator 2 from being affected by the second oscillator 4 when it is working, thereby avoiding mutual interference between the first oscillator 2 and the second oscillator 4 when they are working, and improving the stability of the antenna's signal reception and transmission.
[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the antenna also includes a coaxial line 5, which has an inner core and an outer conductor 51 sleeved on the inner core. The end of the coaxial line 5 passes through the substrate 1, and the inner core and the outer conductor 51 are electrically connected to a oscillator group respectively.
[0046] Understandably, since there are vibrator groups on both opposite sides of the substrate 1, the connector 3 needs to feed both vibrator groups simultaneously. The coaxial line 5 passing through the substrate 1 includes an inner core and an outer conductor 51, which allows the outer conductor 51 to be electrically connected to the vibrator group on one side of the substrate 1, while the inner core can pass through the substrate 1 and be electrically connected to the vibrator group on the other side of the substrate 1. This significantly simplifies the antenna feeding structure and optimizes the antenna radiation structure, better achieving single-feed dual-frequency radiation of the antenna, and resulting in better low-frequency antenna pattern performance and VSWR bandwidth.
[0047] Specifically, in this embodiment, such as Figure 2As shown, the outer conductor 51 is electrically connected to the microstrip line through solder joints 52 sleeved on the outer conductor 51.
[0048] In some specific embodiments, such as Figure 1 and Figure 2 As shown, the substrate 1 is also provided with a limiting member 7, and the coaxial line 5 passes through the limiting member 7 and is spaced apart from the surface of the substrate 1. The limiting member 7 is used to restrict the axial movement of the coaxial line 5.
[0049] It is understandable that by setting the limiting member 7, the vertical distance between the coaxial line 5 and the substrate can be increased to prevent contact interference between the coaxial line 5 and the first oscillator part 2. It can also limit the coaxial line 5 in the axial direction and in the direction perpendicular to the side of the substrate 1, so that the position of the coaxial line 5 relative to the substrate 1 can be fixed, thereby effectively improving the impact of the signal on harmonics during transmission and thus improving the stability of the signal.
[0050] Specifically, the limiting element 7 can be made of insulating materials such as foam or plastic.
[0051] In some embodiments, the first connecting oscillator arm 21 and the first high-frequency oscillator arm 22 have the same oscillator frequency, and the second connecting oscillator arm 41 and the second high-frequency oscillator arm 42 have the same frequency. It is understood that, through the above configuration, the first connecting oscillator arm 21 can also be used as the first high-frequency oscillator arm 22, improving the utilization rate of the first connecting oscillator arm 21.
[0052] In some embodiments, the sum of the lengths of the first connecting oscillator arm 21 and the first low-frequency oscillator arm 23 is 1 / 4 to 3 / 4 of the low-frequency resonant wavelength; the sum of the lengths of the first connecting oscillator arm 21 and the first high-frequency oscillator arm 22 is 1 / 4 to 3 / 4 of the high-frequency resonant wavelength; the sum of the lengths of the second connecting oscillator arm 41 and the second low-frequency oscillator arm 43 is 1 / 4 to 3 / 4 of the low-frequency resonant wavelength; and the sum of the lengths of the second connecting oscillator arm 41 and the second high-frequency oscillator arm 42 is 1 / 4 to 3 / 4 of the high-frequency resonant wavelength.
[0053] It is understandable that by adjusting the sum of the lengths of the first connecting arm 21 and the first low-frequency arm 23, the sum of the lengths of the first connecting arm 21 and the first high-frequency arm 22, and by adjusting the sum of the lengths of the second connecting arm 41 and the second low-frequency arm 43, and the sum of the lengths of the second connecting arm 41 and the second high-frequency arm 42, the radiation frequency range of the antenna during actual use can be adjusted. For example, Figures 7-10 As shown, in this embodiment, the above settings enable the antenna to operate in the low-frequency signal range of 2.39GHz to 2.65GHz and the high-frequency signal range of 5.53GHz to 6GHz, ensuring that the antenna can cover the 2.4GHz and 5.8GHz frequency bands.
[0054] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the connector 3 includes a microstrip line, and the two ends of the microstrip line are electrically connected to two adjacent first connecting oscillator arms 21, respectively.
[0055] Understandably, by setting up the microstrip line, it is only necessary to electrically connect the microstrip line to the feeding device to simultaneously feed the two first elements 2 and the two second elements 4, thereby further optimizing the antenna's feeding structure.
[0056] In some specific embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, in the width direction of the substrate 1, the microstrip line is located between two adjacent first low-frequency vibrator arms 23 and between two adjacent second low-frequency vibrator arms 43, thereby forming a radiating structure of the first low-frequency vibrator arm 23 and the first high-frequency vibrator arm 22 connected to the first connecting vibrator arm 21, and forming a radiating structure of the second low-frequency vibrator arm 43 and the second high-frequency vibrator arm 42 connected to the second connecting vibrator arm 41. This facilitates the adjustment of the antenna impedance to increase and allows for adjustment of the impedance of the dual-frequency antenna to increase the bandwidth of the radiation frequency band of the first vibrator part 2 and the second vibrator part 4, making the performance of the antenna more stable.
[0057] In some embodiments, such as Figure 1 , Figure 3 and Figure 4 As shown, the antenna also includes multiple reflectors 6, each reflector 6 corresponding to a first vibrator 2, and the reflectors 6 are used to enhance the signal of the first vibrator 2.
[0058] It is understandable that reflector 6 can strengthen the signal strength in the preset direction while weakening the signal strength in the opposite direction. Therefore, after setting reflector 6, 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 omnidirectionality of the antenna.
[0059] In some embodiments, such as Figure 4 As shown, the reflector 6 extends along the length of the substrate 1. The length of the reflector 6 is greater than the arm length of the first high-frequency oscillator arm 22 and less than the arm length of the first low-frequency oscillator arm 23.
[0060] It is understandable that when the length of reflector 6 is greater than the arm length of the first high-frequency oscillator arm 22, it can unilaterally amplify the high-frequency oscillator signal, thereby realizing the direction of the high-frequency signal; while at the same time, when the length of reflector 6 is less than the arm length of the first low-frequency oscillator arm 23, it can amplify the low-frequency signal in the same direction, and still achieve a certain degree of omnidirectionality.
[0061] In some specific embodiments, at least one of the two oppositely arranged sides of the substrate 1 is provided with a reflector 6. That is, regardless of which side of the substrate 1 is provided with the oscillator group, a reflector 6 can be provided on the substrate 1 according to actual needs to improve the omnidirectionality of the antenna.
[0062] like Figure 6 As shown, the present invention also discloses a remote controller, including a body 8, a mounting component 9, and the antenna described above. The mounting component 9 is rotatably connected to the body 8. The antenna is disposed within the mounting component 9, and the antenna connector 3 is connected to the body 8.
[0063] The remote controller according to embodiments of the present invention, having the antenna described above, can meet the coverage of commonly used 2.4GHz and 5.8GHz frequency bands, and has good directionality, thereby facilitating the control of other devices through the remote controller, reducing the negative impact of device operation on communication, and ensuring reliable communication during device operation.

[0067] The antenna includes a substrate 1, a vibrator assembly, a connector 3, a coaxial cable 5, a limiting component 7, and a reflector 6.
[0068] The oscillator assembly includes multiple first oscillator sections 2 distributed along the length direction of the substrate 1 and multiple second oscillator sections 4 distributed along the length direction of the substrate 1. The first oscillator sections 2 and 4 are located on both sides of the substrate 1. The first oscillator section 2 includes a first connecting oscillator arm 21, a first high-frequency oscillator arm 22, and a first low-frequency oscillator arm 23. The first connecting oscillator arm 21 extends along the width direction of the substrate 1. A first low-frequency oscillator arm 23 and a first high-frequency oscillator arm 22 are respectively connected to each end of the first connecting oscillator arm 21. The first low-frequency oscillator arm 23 and the first high-frequency oscillator arm 22 extend in the same direction along the length direction of the substrate 1 from the first connecting oscillator arm 21. The second oscillator section 4 includes 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. A second low-frequency oscillator arm 43 and a second high-frequency oscillator arm 42 are respectively connected to each end of the second connecting oscillator arm 41. The second low-frequency oscillator arm 43 and the second high-frequency oscillator arm 42 extend in the same direction along the length direction of the substrate 1 from the second connecting oscillator arm 41. Adjacent second connecting oscillator arms 41 are electrically connected via connectors 3. The first oscillator section 2 and the second oscillator section 4 are respectively located on both sides of the substrate 1. The first high-frequency oscillator arm 22 and the first low-frequency oscillator arm 23 are oriented opposite to the second high-frequency oscillator arm 42 and the second low-frequency oscillator arm 43. The projections of the first connecting oscillator arm 21 and the second connecting oscillator arm 41 on the substrate 1 coincide, and the first oscillator section 2 and the second oscillator section 4 are symmetrically arranged about the first connecting oscillator arm 21. The first connecting oscillator arm 21 and the first high-frequency oscillator arm 22 have the same frequency, and the second connecting oscillator arm 41 and the second high-frequency oscillator arm 42 have the same frequency. The sum of the lengths of the first connecting oscillator arm 21 and the first low-frequency oscillator arm 23 is 1 / 4 to 3 / 4 of the low-frequency resonant wavelength; the sum of the lengths of the first connecting oscillator arm 21 and the first high-frequency oscillator arm 22 is 1 / 4 to 3 / 4 of the high-frequency resonant wavelength; the sum of the lengths of the second connecting oscillator arm 41 and the second low-frequency oscillator arm 43 is 1 / 4 to 3 / 4 of the low-frequency resonant wavelength; the sum of the lengths of the second connecting oscillator arm 41 and the second high-frequency oscillator arm 42 is 1 / 4 to 3 / 4 of the high-frequency resonant wavelength.
[0069] Two adjacent first connecting oscillator arms 21 are electrically connected via a connector 3. The connector 3 includes a microstrip line. A coaxial line 5 has an inner core and an outer conductor 51 sleeved on the inner core. The ends of the coaxial line 5 pass through the substrate 1, and the inner core and outer conductor 51 are electrically connected to one oscillator assembly, respectively. A limiting member 7 is provided on the substrate 1, and the coaxial line 5 passes through the limiting member 7 and is spaced apart from the surface of the substrate 1. The limiting member 7 is used to restrict the axial movement of the coaxial line 5. The two ends of the microstrip line are electrically connected to two adjacent first connecting oscillator arms 21, respectively.
[0070] Each reflector 6 corresponds to a first oscillator section 2, and the reflector 6 is used to amplify the signal of the first oscillator section 2. 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 oscillator arm 22 and less than the arm length of the first low-frequency oscillator arm 23.
