[0034] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.

Moreover, a first feature being "on", "above" or "above" a second feature includes that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0037] It should be understood that the terms "length", "width", "upper", "inner", "axial" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] Reference below Figure 1-Figure 11 The specific structure of the antenna according to the embodiment of the present invention is described.

[0039] like Figure 1-Figure 11 As shown, Figure 1 Disclosed is an antenna, which includes a substrate 1, a first dipole portion 2, and a second dipole portion 3. The first dipole portion 2 is provided on the substrate 1, and the first dipole portion 2 includes a first low-frequency dipole arm 21, a first intermediate-frequency dipole arm 22, and a first high-frequency dipole arm 23 extending along the length direction of the substrate 1, and the first low-frequency dipole arm 21, the first intermediate-frequency dipole arm 22, and the first high-frequency dipole arm 23 are spaced apart and connected to each other along the width direction of the substrate 1. The second diffraction portion 3 and the first diffraction arm are arranged on the same side of the substrate 1. The second diffraction portion 3 includes a second low-frequency diffraction arm 31, a second intermediate-frequency diffraction arm 32 and a second high-frequency diffraction arm 33 extending along the length direction of the substrate 1. The second low-frequency diffraction arm 31, the second intermediate-frequency diffraction arm 32 and the second high-frequency diffraction arm 33 are spaced apart and connected to each other along the width direction of the substrate 1. The extension direction of the first low-frequency diffraction arm 21, the first intermediate-frequency diffraction arm 22 and the first high-frequency diffraction arm 23 is opposite to the extension direction of the second low-frequency diffraction arm 31, the second intermediate-frequency diffraction arm 32 and the second high-frequency diffraction arm 33. The second diffraction portion 3 is electrically connected to the first diffraction portion 2.

[0040] It can be understood that a solution of different frequency bands can be formed by combining one of the first low-frequency dipole arm 21, the first intermediate-frequency dipole arm 22 and the first high-frequency dipole arm 23 with one of the second low-frequency dipole arm 31, the second intermediate-frequency dipole arm 32 and the second high-frequency dipole arm 33. Figure 8As shown, the combination of the first low-frequency dipole arm 21 and the second low-frequency dipole arm 31 can realize the antenna working in the frequency band of 850MHz to 970MHz, the combination of the first intermediate frequency dipole arm 22 and the second intermediate frequency dipole arm 32 can realize the antenna working in the frequency band of 2.38GHz to 2.48GHz, and the combination of the first high-frequency dipole arm 23 and the second high-frequency dipole arm 33 can realize the antenna working in the frequency band of 4.85GHz to 6.0GHz, thereby meeting the front gain requirements of the remote control device for the three frequency bands of 900MHz, 2.4GHz and 5.8GHz. More specifically, as Fig. 9 As shown, when the first low-frequency dipole arm 21 is combined with the second low-frequency dipole arm 31, the antenna can achieve omnidirectional coverage at 900 MHz. Fig.10 As shown, when the first intermediate frequency dipole arm 22 and the second intermediate frequency dipole arm 32 are combined, the antenna can achieve directional coverage at 2.4 GHz, such as Fig.11 As shown, when the first high-frequency dipole arm 23 and the second high-frequency dipole arm 33 are combined, the antenna can achieve directional coverage at 5.8 GHz.

[0041] In this embodiment, if Figure 3 As shown, the antenna further includes a coaxial feed line 4 , which has an inner conductor 41 and an outer conductor 42 . The outer conductor 42 is sleeved on the inner conductor 41 . The inner conductor 41 is electrically connected to the second dipole portion 3 , and the outer conductor 42 is electrically connected to the first dipole portion 2 .

[0042] It can be understood that the coaxial feed line 4 can feed the first dipole portion 2 and the second dipole portion 3 at the same time, thereby eliminating the need to provide an additional electrical connection structure between the first dipole portion 2 and the second dipole portion 3, which is beneficial for increasing the area requirement when the first dipole portion 2 and the second dipole portion 3 are installed on the substrate 1, thereby significantly simplifying the feeding structure of the antenna and optimizing the radiation structure of the antenna.

[0043] In this embodiment, if Figure 4 and Figure 5 As shown, the first low-frequency dipole arm 21 includes a first horizontal section 211, a first serpentine section 212 and a first grid section 213, and the first horizontal section 211 is connected to the first grid section 213 through the first serpentine section 212. The second low-frequency dipole arm 31 includes a second horizontal section 311, a second serpentine section 312 and a second grid section 313, and the second horizontal section 311 is connected to the second grid section 313 through the second serpentine section 312.

[0044] It is understandable that the first grid segment 213 and the first serpentine segment 212 can both be arranged with a relatively long line segment in a limited space, thereby reducing the energy transmission loss during the operation of the first low-frequency dipole arm 21 and the second low-frequency dipole arm 31. In addition, during the later debugging of the signal, the openings at different positions of the first serpentine segment 212 and the second serpentine segment 312 can be short-circuited or the different squares of the first grid segment 213 and the second grid segment 313 can be disconnected to complete signal debugging under different conditions, which greatly improves the convenience and efficiency of signal debugging.

[0045] In this embodiment, if Figure 4 and Figure 5 As shown, the first grid segment 213 has first grid openings 2131 spaced apart along the length direction of the substrate 1, and the second grid segment 313 has second grid openings 3131 spaced apart along the length direction of the substrate 1; the first grid opening 2131 at one end of the first grid segment 213 away from the first serpentine segment 212 is open, or the second grid opening 3131 at one end of the second grid segment 313 away from the second serpentine segment 312 is open.

[0046] It is understandable that the first grille opening 2131 at the tail of the first grille segment 213 or the second grille opening 3131 at the tail of the second grille segment 313 is open, which can facilitate the adjustment of the resonance length and improve the adjustability of the first low-frequency dipole arm 21 and the second low-frequency dipole arm 31. Specifically, in this embodiment, the first grille opening 2131 at the tail of the first grille segment 213 is open.

[0047] Of course, in other embodiments of the present invention, such as Figure 6 As shown, the first low-frequency dipole arm 21 and the second low-frequency dipole arm 31 may also adopt a common L-shaped microstrip line structure, and the antenna may also operate in the frequency band of 850 MHz to 970 MHz. The specific structures of the first low-frequency dipole arm 21 and the second low-frequency dipole arm 31 may be determined according to actual needs.

[0048] In this embodiment, if Figure 4 and Figure 5 As shown, the first high-frequency dipole arm 23 includes a first connecting section 231 and a first extending section 232. The first connecting section 231 is extended along the width direction of the substrate 1 and connected to the first low-frequency dipole arm 21 and the first intermediate-frequency dipole arm 22. The first extending section 232 is extended along the length direction of the substrate 1 and connected to the first connecting section 231. The second high-frequency dipole arm 33 includes a second connecting section 331 and a second extending section 332. The second connecting section 331 is extended along the width direction of the substrate 1 and connected to the second low-frequency dipole arm 31 and the second intermediate-frequency dipole arm 32. The second extending section 332 is extended along the length direction of the substrate 1 and connected to the second connecting section 331.

[0049] It can be understood that the first connecting section 231 can facilitate the connection of the first high-frequency dipole arm 23, the first low-frequency dipole arm 21 and the first intermediate-frequency dipole arm 22, so that the coaxial feed line 4 can be electrically connected to only one area of ​​the first dipole part 2 to feed the first high-frequency dipole arm 23, the first intermediate-frequency dipole arm 22 or the first low-frequency dipole arm 21. The second connecting section 331 can facilitate the connection of the second high-frequency dipole arm 33, the second low-frequency dipole arm 31 and the second intermediate-frequency dipole arm 32, so that the coaxial feed line 4 can be electrically connected to only one area of ​​the second dipole part 3 to feed the second high-frequency dipole arm 33, the second intermediate-frequency dipole arm 32 or the second low-frequency dipole arm 31. In addition, the first connecting section 231 and the first extension section 232 can form the first high-frequency dipole arm 23 into an L-shaped dipole structure, and the second connecting section 331 and the second extension section 332 can form the second high-frequency dipole arm 33 into an L-shaped dipole structure.

[0050] In this embodiment, the length of the first low-frequency dipole arm 21 and the length of the second low-frequency dipole arm 31 are both 1 / 8-3 / 4 of the low-frequency resonance wavelength; the length of the first intermediate-frequency dipole arm 22 and the length of the second intermediate-frequency dipole arm 32 are both 1 / 8-3 / 4 of the intermediate-frequency resonance wavelength; the length of the first high-frequency dipole arm 23 and the length of the second high-frequency dipole arm 33 are both 1 / 8-3 / 4 of the high-frequency resonance wavelength.

[0051] Specifically, in this embodiment, the first low-frequency dipole arm 21 further includes a third connecting section 214, which is connected to the first horizontal section 211, and the second low-frequency dipole arm 31 further includes a fourth connecting section 314, which is connected to the second horizontal section 311. The length of the first low-frequency dipole arm 21 is the sum of the lengths of the third connecting section 214, the first horizontal section 211, the first serpentine section 212, and the first grille section 213, and the length of the second low-frequency dipole arm 31 is the sum of the lengths of the fourth connecting section 314, the second horizontal section 311, the second serpentine section 312, and the second grille section 313. The length of the first high-frequency dipole arm 23 is the sum of the lengths of the first connecting section 231 and the first extension section 232, and the length of the second high-frequency dipole arm 33 is the sum of the lengths of the second connecting section 331 and the second extension section 332.

[0052] It can be understood that by adjusting the lengths of the first low-frequency dipole arm 21, the second low-frequency dipole arm 31, the first intermediate-frequency dipole arm 22, the second intermediate-frequency dipole arm 32, the first high-frequency dipole arm 23 and the second high-frequency dipole arm 33, the radiation frequency band range of the antenna during actual use can be adjusted, for example, Figure 8-Figure 11As shown, in this embodiment, the above settings can enable the antenna to operate in three frequency bands: 850MHz to 970MHz, 2.38GHz to 2.48GHz, and 4.85GHz to 6.0GHz, thereby ensuring that the antenna can cover the three frequency bands of 900MHz, 2.4GHz, and 5.8GHz.

[0053] In this embodiment, if Figure 1 and Figure 2 As shown, the antenna also includes a reflector 5, which is arranged on the substrate 1. The arm length of the reflector 5 is smaller than the arm length of the first low-frequency dipole arm 21 and the second low-frequency dipole arm 31, and is larger than the arm length of the first intermediate frequency dipole arm 22, the first high frequency dipole arm 23, the second intermediate frequency dipole arm 32 and the second high frequency dipole arm 33.

[0054] It can be understood that when the length of the reflector 5 is greater than the arm length of the first intermediate frequency dipole arm 22, the first high frequency dipole arm 23, the second intermediate frequency dipole arm 32 and the second high frequency dipole arm 33, it can play a unilateral strengthening role on the high frequency signal, thereby realizing the direction of the high frequency signal and the intermediate frequency signal; and at the same time, the length of the reflector 5 is less than the arm length of the first low frequency dipole arm 21 and the second low frequency dipole arm 31, it can play a strengthening role on the low frequency signal in the same direction, and still can achieve a certain omnidirectionality.

[0055] In this embodiment, a reflector 5 is provided on at least one of the two side surfaces of the substrate 1. Regardless of which side surface of the substrate 1 the first vibrator portion 2 and the second vibrator portion 3 are provided, the reflector 5 can be provided on the front surface, the back surface or both surfaces of the substrate 1 according to actual needs.

[0056] In this embodiment, the reflector 5 is a microstrip line structure, such as Figure 1 and Figure 6 As shown, the reflector 5 can be formed into a microstrip line structure or split into two microstrip line structures, and its specific structure can be determined according to actual needs.

[0057] In this embodiment, if Figure 2 As shown, the antenna further includes a director 6 , which is disposed on the substrate 1 .

[0058] It is understandable that the director 6 can enhance the signal strength in a single direction without suppressing the signal in the non-working direction, thereby also playing the role of enhancing the signal in a single direction.

[0059] The director 6 can be arranged on the same surface of the substrate 1 with the first oscillator part 2 and the second oscillator part 3, or on the other surface of the substrate 1, or on the same surface as the reflector 5. Its specific arrangement can be determined according to actual needs.

[0060] In this embodiment, the first vibrator part 2 and the second vibrator part 3 are provided on at least one of the two sides of the substrate 1 .

[0061] It is understandable that when the first dipole portion 2 and the second dipole portion 3 are provided on both sides of the substrate 1, the antenna can enhance the signal reception and transmission effects, thereby improving the stability of signal transmission, thereby improving the reliability of the antenna.

[0062] like Figure 7 As shown, the present invention also discloses a remote control device, comprising a main body 7, a shell 8 and the above-mentioned antenna. The shell 8 is rotatably connected to the main body 7. The antenna is arranged in the shell 8.

[0063] The remote control device according to the embodiment of the present invention has the antenna described above, which can achieve strong directionality in medium and high frequencies and weak directionality in low frequencies, meeting the remote control device's requirements for front gain in the 900 MHz, 2.4 GHz and 5.8 GHz frequency bands.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
