[0043] In order to illustrate the technical solutions described in the present invention, the following will be described in detail with reference to specific accompanying drawings and embodiments.

[0044] Please refer to Figures 1 to 3 , an embodiment of the present invention provides an antenna, including:

[0045] A container 100, the container 100 is provided with a receiving cavity 110 having an opening 111, and a first feeding part 120 is provided at the bottom of the receiving cavity 110. The container 100 can be, but is not limited to, a vase, a flower pot or other structures capable of inserting items;

[0046] At least one first radiation element 200, inserted into the receiving cavity 110 through the opening 111 and electrically connected to the first feeding part 120; and

[0047] A feeding element 400, disposed outside the container 100 and electrically connected to the first feeding part 120.

[0048] It can be understood that, as Figure 1As shown, in the antenna of this embodiment, only one first radiating element 200 is inserted into the receiving cavity 110 of the container 100. According to the actual situation, the user can adjust the number of the first radiating elements 200; in Figure 9 And Figure 10 In their respective corresponding embodiments, multiple first radiating elements 200 are inserted into the receiving cavity 110 of the container 100.

[0049] The antenna of the embodiment of the present invention includes a container 100, at least one first radiating element 200, and a feeding element 400. Among them, the container 100 is provided with a receiving cavity 110 having an opening 111, and a first feeding portion 120 is provided at the bottom of the receiving cavity 110; the first radiating element 200 is inserted into the receiving cavity 110 from the opening 111 and is electrically connected to the first feeding portion 120; the feeding element 400 is arranged outside the container 100 and is electrically connected to the first feeding portion 120. The customer can insert different first radiating elements 200 into the receiving cavity 110 or adjust the number of the first radiating elements 200 according to the requirements to adjust the radiation frequency covered by the antenna of the embodiment of the present invention, so as to meet the frequency band requirements of different customers for the antenna. Moreover, the above structure is simple, making the antenna of the embodiment of the present invention easy to produce and assemble, effectively improving the assembly efficiency, with low cost, and meeting the purchasing power of most consumers.

[0050] It should be noted that since the antenna of the embodiment of the present invention adjusts the radiation frequency covered by the antenna of the embodiment of the present invention by inserting different first radiating elements 200 or adjusting the number of the first radiating elements 200 in the receiving cavity 110, compared with the traditional antenna, the antenna of the embodiment of the present invention uses the first radiating element 200 alone to debug the effective radiation bandwidth, rather than using an external circuit board to complete the antenna design. Therefore, there is no need to additionally set a matching circuit or a filtering circuit to make the antenna meet the corresponding signal transmission parameter requirements, so that the circuit loss and the cost of materials such as the circuit board can be reduced.

[0051] Specifically, in an embodiment of the present invention, in combination with Figure 3 And Figure 7, the first radiator 200 includes a radiator body 210 and a decorative body 220 wrapped around the radiator body 210. One end of the radiator body 210 located inside the accommodation cavity 110 is electrically connected to the first feeding portion 120. Currently, the consumer market is saturated, and consumers' demands for products are not only limited to the functionality of the products. Therefore, if a product only has its function without other attributes, it is difficult to win the market. In the embodiment of the present invention, by providing a decorative body 220 outside the radiator body 210, the antenna of the embodiment of the present invention is made more beautiful, thereby increasing the product competitiveness of the antenna of the embodiment of the present invention. It should be noted that in the antenna of the embodiment of the present invention, the appearance of the decorative body 220 can be a fake flower, and according to the actual situation, the appearance of the decorative body 220 can also be other shapes, such as fake grass, etc.

[0052] Specifically, in an embodiment of the present invention, the radiator body 210 is in a rod shape. One end of the radiator body 210 located inside the accommodation cavity 110 is exposed outside the decorative body 220, that is, one end of the radiator body 210 located inside the accommodation cavity 110 is not wrapped by the decorative body 220, so as to be in direct contact with the first feeding portion 120, thereby realizing the electrical connection between the radiator body 210 and the first feeding portion 120.

[0053] Optionally, the radiator body 210 is made of a metal material, and specifically, metal materials such as copper (Cu), aluminum (Al), and silver (Ag) can be selected; the decorative body 220 is made of a non-metal material, and specifically, non-metal materials such as plastic and cloth can be selected.

[0054] Furthermore, since the radiator body 210 is made of a metal material, it is prone to oxidation and rusting, thereby affecting the service life of the first radiator 200 of the embodiment of the present invention. To solve the above problems, a protective layer (not shown) can be provided on the outer surface of the radiator body 210 to prevent the radiator body 210 from oxidizing and rusting.

[0055] Specifically, in an embodiment of the present invention, the length of the radiator body 210 is greater than the height of the container 100, so that the radiator body 210 can be exposed from the opening 111 of the accommodation cavity 110, and the decorative body 220 wrapped around the radiator body 210 can be exposed from the opening 111 of the accommodation cavity 110, which is more beautiful.

[0056] It can be understood that according to the actual situation, the length of the radiator body 210 can also be less than or equal to the height of the container 100. In this case, to ensure the ornamental property of the antenna of the embodiment of the present invention, the decorative body 220 wrapped around the radiator body 210 can also be exposed from the opening 111 of the accommodation cavity 110, and the present invention does not make any restrictions here.

[0057] Optionally, the length of the radiator 210 is 0.01 m (meter) to 1 m to cover the frequency band of 76 MHz to 6 GHz corresponding to TV signal reception. For example, the length of the radiator 210 can be at least one of 0.01 m, 0.1 m, 0.15 m, 0.2 m, 0.25 m, 0.3 m, 0.35 m, 0.4 m, 0.45 m, 0.5 m, 0.55 m, 0.6 m, 0.65 m, 0.7 m, 0.75 m, 0.8 m, 0.85 m, 0.9 m, 0.95 m, and 1 m. The manufacturer can set multiple lengths for users to choose by themselves. It should be noted that the antenna according to the embodiment of the present invention can adjust the frequency band covered by the antenna by setting radiators 210 with different lengths in the accommodation cavity 110.

[0058] As a preferred embodiment, in the antenna according to the embodiment of the present invention, the length of the radiator 210 is 0.1 m to 0.4 m to cover the frequency band of 450 MHz to 900 MHz corresponding to signal reception. The above frequency band is the frequency usage range required by ordinary household users. In this embodiment, the length of the part of the radiator 210 exposed from the opening 111 of the accommodation cavity 110 can be, but is not limited to, 0 m to 0.3 m.

[0059] Compared with traditional antenna products, the antenna according to the embodiment of the present invention has a wider bandwidth, can meet more connection requirements of users, and can implement more functions desired by users, such as signal transmission and reception of TV products, signal transmission and reception of WIFI products, and signal transmission and reception of mobile phone products.

[0060] Specifically, in an embodiment of the present invention, in order to enable the first feeding part 120 to be in effective contact with the radiator 210, a layer of metal powder can be laid on the first feeding part 120. When the first radiating element 200 is inserted into the accommodation cavity 110, one end of the radiator 210 located in the accommodation cavity 110 can be in full contact with the first feeding part 120. In this embodiment, the surface of the first feeding part 120 facing the radiator 210 can be set as a rough surface so that the metal powder can be in full contact with the first feeding part 120, and further enable the first feeding part 120 to be in effective contact with the radiator 210.

[0061] Specifically, in an embodiment of the present invention, the first feeding part 120 is a metal sheet provided at the bottom of the accommodation cavity 110, and metal materials such as copper, aluminum, and silver can be specifically selected. In this embodiment, the metal sheet serving as the first feeding part 120 is attached to the bottom of the accommodation cavity 110; or the metal sheet serving as the first feeding part 120 is integrally formed with the container 100, so as to arrange the metal sheet serving as the first feeding part 120 at the bottom of the accommodation cavity 110. Of course, according to actual situation selection, other methods can be adopted to arrange the metal sheet serving as the first feeding part 120 at the bottom of the accommodation cavity 110, and the present invention does not limit this here.

[0062] Specifically, in an embodiment of the present invention, the antenna further includes a plurality of second radiating elements 300 provided on the side wall of the accommodation cavity 110. The second radiating elements 300 are electrically connected to the first feeding portion 120, thereby improving the radiation coverage of the antenna in the embodiment of the present invention. In a preferred embodiment, the plurality of second radiating elements 300 are uniformly arranged on the side wall of the accommodation cavity 110 in the circumferential direction, so that the antenna in the embodiment of the present invention maintains omnidirectional radiation performance on the horizontal plane.

[0063] Optionally, the second radiating element 300 can be, but is not limited to, a metal sheet. Specifically, metal materials such as copper, aluminum, and silver can be selected. The length of the second radiating element 300 is 10 mm to 100 mm. For example, the second radiating element 300 can be a metal sheet with a length of 10 mm (millimeter), 35 mm, 70 mm, or 100 mm, etc., so as to radiate and cover the available frequency band of 800 MHz to 6 GHz of the user.

[0064] Specifically, in an embodiment of the present invention, the metal sheet serving as the second radiating element 300 is attached to the side wall of the accommodation cavity 110; or, the metal sheet serving as the second radiating element 300 is integrally formed with the container 100, so as to arrange the metal sheet serving as the second radiating element 300 on the side wall of the accommodation cavity 110. Of course, according to the selection of the actual situation, other methods can be adopted to arrange the metal sheet serving as the second radiating element 300 on the side wall of the accommodation cavity 110, and the present invention does not limit this here.

An accommodation cavity 110 is formed by enclosing between the bottom shell 130 and the body shell 140. The first feeding portion 120 is provided on the bottom shell 130. To avoid the body shell 140 causing loss to the radiation intensity of the first radiating element 200, it is advisable to use an insulating material to make the body shell 140, that is, a material that does not conduct electricity and does not conduct magnetism needs to be used to make the body shell 140, so as to reduce the signal loss of the antenna. As an alternative embodiment, the body shell 140 is one of a ceramic part, a glass part, and a plastic part. The above materials have less signal loss and can reduce the signal loss of the antenna.
