In a first aspect of the present embodiment, referring to fig. 1 and fig. 2, an intelligent television antenna 1000 is provided, where the antenna 1000 includes a PCB board 100, an antenna body 200, an external connector 300, and a fixing member 400. The PCB 100 includes a metal cover plate 110 and a substrate 120, the metal cover plate 110 covers a surface of the substrate 120, and the metal cover plate 110 includes a ground plane 111 and a radio frequency circuit 112. The antenna body 200 is disposed on the substrate 120, the antenna body 200 includes a feeding structure 210 and a grounding structure 220, the feeding structure 210 is connected to the rf circuit 112, and the grounding structure 220 is connected to the ground plane 111. The external connector 300 is connected to the antenna body 200. The fixing member 400 is used to fix the external connector 300 to the antenna body 200, and both the external connector 300 and the antenna body 200 are abutted against the fixing member 400. The external connector 300 includes a feeding pin 321 and a grounding pin 322, and both the feeding pin 321 and the grounding pin 322 are electrically connected to the antenna body 200, so that the external connector 300 and the antenna body 200 emit radiation of a predetermined frequency together.

Through the above technical solution, the feeding structure 210 in the antenna body 200 is connected to the feeding pin 321, the grounding structure 220 is connected to the grounding pin 322, the external connector 300 is used as a part of the radiation structure of the antenna body 200 to participate in the radiation of the signal, and the external connector 300 and the antenna body 200 jointly emit the radiation of the preset frequency. The smart tv is usually embedded with a large area of metal back plate 2000, or a reinforced concrete wall, which results in poor radiation effect of the antenna 1000. Under the condition that the radiation environment is not ideal, the technical scheme can overcome the interference of the external environment on the antenna 1000, realize the radiation of the antenna 1000 with high efficiency and wide frequency band, provide a good foundation for the signal receiving and covering of products, and simultaneously, the antenna body 200 occupies a very small area on the PCB 100, thereby being convenient for layout and saving cost.

It will be appreciated that the feed pin 321 is coupled to the feed structure 210, such that excitation signals from the rf circuitry 112 are transmitted through the feed structure 210 to the external connector 300, the length of the radiation structure of the entire antenna 1000 is increased with the area of the antenna body 200 on the PCB board 100 unchanged, meanwhile, the external connector 300 and the simultaneous ground pin 322 are connected to the ground plane 111 through the ground structure 220, the extension direction of the ground plane 111 is opposite to that of the external connector 300, a mirror current with the direction opposite to that of the radiation current on the external connector 300 is formed on the ground plane 111, so as to emit a mirror resonance with the direction opposite to that of the main resonance radiation around the ground plane 111, in the limited area of the antenna body 200 on the PCB 100, the length of the radiation structure of the antenna 1000 is effectively extended, the radiation emitted by the external connector 300 and the antenna body 200 together meets the requirement of the 5GHz frequency band of WIFI 802.11 ax.

Referring to fig. 3 and 4, in some embodiments, the grounding structure 220 has a first positioning hole 211, the feeding structure 210 has a second positioning hole 221, the feeding pin 321 has a first protrusion 3211 matching with the first positioning hole 211, and the grounding pin 322 has a second protrusion 3221 matching with the second positioning hole 221. The first positioning hole 211 is adapted to the first protrusion 3211, and the second positioning hole 221 is adapted to the second protrusion 3221, so that when the external connector 300 is mounted on the antenna body 200 in a matching manner, the external connector 300 and the antenna body 200 can be positioned more conveniently and more accurately. In some embodiments, the antenna body 200 and the external connector 300 are fixedly connected by welding, and compared with other connection methods such as glue connection, the electrical connection between the antenna body 200 and the external connector 300 is better.

In some embodiments, the grounding structure 220 is provided with a plurality of connecting elements 230 at a position close to the feeding structure 210, the plurality of connecting elements 230 are connected to the plurality of ground planes 111, and the connecting elements 230 on the grounding structure 220 can further reduce the influence of the current on the grounding structure 220 near the feeding structure 210. It is understood that in an alternative embodiment, the connecting member 230 is disposed at other positions around the grounding structure 220, and is not limited in this application.

In some embodiments, the connection 230 is in the form of a metalized via. The diameters of all the metalized through holes are 0.2-0.4 mm, the hole intervals of the metalized through holes are 0.5-1.0 mm, the diameters and the intervals of the metalized through holes are adjusted according to actual processing requirements, the diameters and the intervals of the metalized through holes are required to be controlled, the diameters of the through holes are too large, a plurality of metal cover plates 110 cannot be effectively connected, and the through holes are too small, so that the processing difficulty is caused. Similarly, the upper layer and the lower layer cannot be effectively connected due to too large space between the through holes, and the processing difficulty is caused due to too small space. The optimal size and spacing range of the metalized via holes is given through optimal design and repeated experiments. In a specific embodiment, the metallized holes have a diameter of 0.3 mm and a pitch of 0.7 mm, which ensures that a plurality of ground planes 111 can be effectively connected.

Referring to fig. 4, in some embodiments, the external connector 300 includes a first portion 310 and a second portion 320, the first portion 310 is parallel to the PCB board 100, the second portion 320 is perpendicular to the first portion 310, the second portion 320 extends from one side of the first portion 310 in a direction toward the PCB board 100, and the feeding pin 321 and the grounding pin 322 are disposed on the second portion 320.

It can be understood that when the included angle between the first portion 310 and the PCB 100 is an acute angle, the distance between the first portion 310 and the metal cover plate 110 is smaller than that when the first portion 310 is parallel to the PCB 100, so that the radiation on the first portion 310 is more affected by the metal cover plate 110, which is inconvenient for the radiation of the antenna 1000; when the included angle between the first portion 310 and the PCB 100 is an obtuse angle, the distance between the first portion 310 and the metal cover plate 110 is greater than the distance between the first portion 310 and the metal cover plate 110 when the first portion 310 is parallel to the PCB 100, which results in an excessively large occupied space of the external connector 300 and affects the internal layout of the smart television. The height of the distance between the first portion 310 and the PCB 100 is selected to be 4 mm-5 mm, such as 4 mm, 4.5 mm or 5 mm, for widening the bandwidth of the antenna 1000 without occupying too much height space.

It will be appreciated that in an alternative embodiment, the length of feed pin 321 in the x-axis direction on second portion 320 is greater than the length of ground pin 322 in the x-axis direction to match the impedance of feed pin 321 on second portion 320.

Referring to fig. 4, the first portion 310 is provided with a first gap 311 along the length direction, the feeding pin 321 and the grounding pin 322 are arranged at intervals to form a second gap 323, and the first gap 311 is communicated with the second gap 323 through a communicating gap 330. It will be appreciated that the arrangement of the first gap 311, the second gap 323 and the communicating gap 330 allows the rf current to further increase the electrical length of the connector 300 without changing the area of the connector 300. Specifically, the distance of the communicating gap 330 along the x-axis direction is 0.9 mm to 1.1 mm, such as 0.9 mm, 1.0 mm, or 1.1 mm.

Referring to fig. 4, in an alternative embodiment, the distance of the second gap 323 along the x-axis direction is greater than the distance of the communicating gap 330 along the x-axis direction. Specifically, when the distance of the communication gap 330 along the x-axis direction satisfies a specific condition, the rf current may directly pass through the communication gap 330, and meanwhile, the rf current may also bypass the communication gap 330, so that the transmission path of the rf current on the external connection component 300 is increased, the electrical lengths of the various transmission paths are different, so that the radiation frequencies generated by the various transmission paths are different, and the various radiation frequencies are coupled with each other, so as to increase the bandwidth of the antenna 1000.

Specifically, in the antenna 1000 provided in the embodiment of the present application, the length direction of the first portion 310 is the x-axis direction shown in fig. 1 and 2, the width direction of the first portion 310 is the y-axis direction shown in fig. 1 and 2, and the height direction of the first portion 310 is the z-axis direction shown in fig. 1 and 2.

Referring to fig. 5, in some embodiments, the fixing member 400 includes a supporting portion 410 and two fixing portions 420, the fixing portions 420 are fixedly connected to the PCB board 100, and the supporting portion 410 abuts against the external connector 300. It can be understood that the external connector 300 is generally made of a metal plate bent due to the need of conducting electricity to emit radiation, and the metal plate is easily deformed by an external force or deformed by gravity, and the deformation of the external connector 300 can seriously affect the normal use of the antenna 1000, so that the external connector 300 needs to be fixed on the PCB 100 by the fixing member 400.

Specifically, the fixing member 400 is made of plastic, and the fixing member 400 made of plastic increases the average dielectric constant of the environment outside the antenna 1000 to some extent, so that the antenna 1000 can be further reduced in size in design. It should be understood that the supporting portion 410 and the two fixing portions 420 are integrally formed, and may also be fixedly connected by a connection method such as glue connection or screw connection, which is not limited in the present application.

Referring to fig. 5, in an alternative embodiment, the fixing portion 420 includes a cross bar 411 and two legs 412, the first portion 310 and the second portion 320 are both abutted against the cross bar 411, and the legs 412 are connected to the fixing portion 420. It can be understood that the two legs 412 and the cross bar 411 together form a receiving slot for receiving the first portion 310 to limit the displacement of the external connector 300 along the x-axis direction, while the abutting surfaces of the cross bar 411 and the second portion 320 limit the displacement of the external connector 300 along the y-axis direction, and the abutting surfaces of the cross bar 411 and the first portion 310 limit the displacement of the external connector 300 along the z-axis direction, so that the connecting member 230 maintains a fixed state in installation fixation and normal use. Specifically, the receiving groove further includes a guide surface to facilitate the insertion of the connector 230 into the receiving groove during installation and fixation.

Referring to fig. 2 and 5, in an alternative embodiment, the PCB 100 is provided with a first groove 130, the fixing portion 420 is provided with a second groove 421, and the first groove 130 and the second groove 421 are engaged with each other so that the fixing portion 420 is fixed on the PCB 100. Specifically, the first groove 130 is adapted to the second groove 421, that is, the distance of the first groove 130 along the x-axis direction is equal to the thickness of the fixing portion 420 along the x-axis direction, and the distance of the second groove 421 along the z-axis direction is equal to the thickness of the PCB 100, so that the first groove 130 and the second groove 421 are engaged with each other, the fixing member 400 is ensured to be fixed on the PCB 100, and the fixed connection relationship of the external connector 300 on the antenna body 200 is further ensured.

Referring to fig. 6a, the S-parameter of the antenna 1000 shows the broadband nature of the return loss of the antenna 1000. In the range of the frequency of the antenna 1000 provided by the application being 5.07GHz-5.96GHz, the values of S (1,1) parameters are all less than or equal to-10 db and can reach-20 db at the lowest, the return loss meets the requirement of a broadband, and the frequency of the antenna 1000 covers the frequency of the 5GHz broadband.

Referring to fig. 6b, an efficiency graph of the antenna 1000 shows the radiation efficiency capability of the antenna 1000 over its operating bandwidth. The efficiency value of the antenna 1000 provided by the application is greater than-0.5 db in the frequency range of 5.1GHz-5.8GHz, the efficiency value meets the requirement of a broadband, and the frequency of the antenna 1000 covers the frequency of the 5GHz broadband.

Through the S parameter in fig. 6a and the efficiency curve in fig. 6b, it can be understood that the antenna 1000 provided in the present application successfully overcomes the metal external environment with a large area and a short distance in the smart television, and the influence of the suppression radiation and the compressed bandwidth on the antenna 1000 is caused, thereby realizing the radiation of the antenna 1000 with high efficiency and a wide frequency band, providing a good foundation for the signal reception and the coverage of the product, and meanwhile, the antenna body 200 occupies a very small area on the PCB 100, and is convenient for layout and cost saving.

Referring to fig. 7 and 8, a second aspect of the embodiment of the present application provides a smart television, which includes a metal back plate 2000, a housing 3000, and a smart television antenna 1000. The housing 3000 and the metal back plate 2000 together form an accommodation space, and the smart tv antenna 1000 is installed in the accommodation space.

The fixing member 400 is used to fix the external connector 300 to the antenna body 200, and both the external connector 300 and the antenna body 200 are abutted against the fixing member 400. The external connector 300 includes a feeding pin 321 and a grounding pin 322, and both the feeding pin 321 and the grounding pin 322 are electrically connected to the antenna body 200, so that the external connector 300 and the antenna body 200 emit radiation of a predetermined frequency together.

Through the above technical solution, the feeding structure 210 in the antenna body 200 is connected to the feeding pin 321, the grounding structure 220 is connected to the grounding pin 322, the external connector 300 is used as a part of the radiation structure of the antenna body 200 to participate in the radiation of the signal, and the external connector 300 and the antenna body 200 jointly emit the radiation of the preset frequency.
