Because of the B2 / 4 / 66 intermediate frequency ENDC requirement, such as B5-N2, B5-N4 and N5-N66 frequency bands are particularly important, because the diversity antenna intermediate frequency is also a transmitting power, the diversity antenna is placed above the lower flip cover mainboard and is located at the flip cover shaft position of the mobile phone. Because the corner environment of the lower flip cover is relatively poor, it is affected by the shaft and other devices. The user requires that the intermediate frequency transmitting frequency band should reach-4.5dB of efficiency, and the existing antenna intermediate frequency transmitting efficiency is only about-5dB, which cannot meet the user's demand.

[0022] The high-performance terminal antenna and mobile terminal proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the explanation of the embodiments of this utility model. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, different figures may emphasize different aspects and sometimes use different proportions.

[0023] Currently, modern 5G communication includes standalone (SA) and non-standalone (NSA) network communication. NSA communication involves simultaneous operation of 5G and 4G networks, employing dual connectivity of 4G LTE and 5G NR. This was one of the NSA network deployment methods used in the early stages of 5G network construction, leveraging the power / gain (i.e., high speed) of 5G while utilizing the core network of 4G / EPC to improve internet speed. Currently, curved-screen flip phones are popular due to their novel appearance. To satisfy both aesthetic requirements and achieve high internal performance, this invention provides a high-performance terminal antenna.

[0024] This high-performance terminal antenna can be used in various mobile terminals, such as mobile phones, tablets, or laptops. This invention does not limit the application scenario of the high-performance terminal antenna; it can be used with any mobile terminal device.

[0025] like Figure 1 As shown, specifically, the high-performance terminal antenna includes a first radiating antenna 10 and a second radiating antenna 7. The first radiating antenna 10 and the second radiating antenna 7 are coupled together to form a coupling gap 8. The first radiating antenna 10 includes a first antenna stub 6, a second antenna stub 3, a third antenna stub 4, and a feed point 1 connected in sequence. The feed point 1 is electrically connected to the first antenna stub 6. The second radiating antenna 7 includes a ground point 2 and a fourth antenna stub. The ground point 2 and the feed point 1 are respectively located on both sides of the coupling gap 8.

[0026] With this configuration, the high-performance terminal antenna of this invention can not only extend the main branches of the radiation area to couple with each other, but also effectively improve the overall radiation frequency and radiation efficiency of the antenna.

[0027] The diversity antenna used in flip phones has B2 / 4 / 66 intermediate frequency (IF) ENDC requirements, such as combinations of B5-N2, B5-N4, and B5-N66 bands. The IF is mainly in the 1700-2200MHz band, with the 1700-2000MHz transmission band being particularly important because the diversity antenna's IF also carries transmission power. The diversity antenna is placed above the lower flip motherboard, located at the flip hinge of the phone. Due to the poor environment in the corner of the lower flip, and the influence of the hinge and other components, the customer requires an IF transmission efficiency of -4.5dB. The alumni antenna's IF transmission efficiency is only around -5dB, which does not meet the customer's requirements.

[0028] This utility model's high-performance terminal antenna adopts an antenna form similar to a deformed dipole. The antenna is used in a flip phone, located at the hinge of the flip cover. The antenna routing can be adjusted synchronously according to the shape of the phone or mobile terminal device casing. Both feed point 1 and ground point 2 require large-area and long branches, and the branches of feed point 1 and ground point 2 are not connected; that is, a coupling gap 8 is provided between feed point 1 and ground point 2. The overall antenna uses a large-area coupling method between ground point 2 and feed point 1, with a large-area branch extending from the feed point, namely the second antenna stub 3. Ground point 2 also extends a long branch, namely the second radiating antenna 7, which couples with the first radiating antenna 10. Simultaneously, feed point 1 extends a small branch towards ground point 2, namely the first antenna stub 6. Thus, as... Figure 2The intermediate frequency band shown can achieve higher antenna efficiency, with the intermediate frequency transmission band efficiency reaching -3.6dB, which can meet the customer's efficiency requirement of -4.5dB.

[0029] Preferably, the first radiating antenna 10 and the second radiating antenna 7 are coupled together to form an F-shaped high-performance terminal antenna. The first radiating antenna 10 is F-shaped, and the first antenna segment 6 is perpendicularly arranged to the second antenna segment 3 and the third antenna segment 4. The first radiating antenna 10 also includes a connecting segment 5, which connects the second antenna segment 3 and the third antenna segment 4. The second antenna segment 3 controls a frequency band of 1700MHz-2200MHz, the third antenna segment 4 is configured to control a frequency band of 1750MHz-2250MHz, and the connecting segment 5 is configured to control a frequency band of 2500MHz-3500MHz. The distance between the feed point 1 and the ground point 2 ranges from 5mm to 8mm, and the gap of the coupling slot 8 ranges from 0.6mm to 1mm. The length of the second antenna segment 3 ranges from 20mm to 25mm, and the width ranges from 15mm to 20mm. The width of the connecting segment 5 ranges from 0.6mm to 1.2mm. The first antenna stub 6 extends from the feed point 1 towards the ground point 2, and the length of the first antenna stub 6 ranges from 8mm to 12mm, and the width ranges from 2.5mm to 4mm. The second radiating antenna 7 has a length range of 25mm to 30mm and a width range of 7mm to 9mm.

[0030] This invention provides a high-performance terminal antenna and mobile terminal device. The high-performance terminal antenna includes a first radiating antenna 10 and a second radiating antenna 7, which are coupled together to form a coupling gap 8. The first radiating antenna 10 includes a first antenna stub 6, a second antenna stub 3, a third antenna stub 4, and a feed point 1 connected in sequence. The feed point 1 is electrically connected to the first antenna stub 6. The second radiating antenna 7 includes a ground point 2 and a fourth antenna stub, with the ground point 2 and the feed point 1 located on opposite sides of the coupling gap 8. This high-performance terminal antenna not only extends the main branches of the radiating area and couples them together, but also effectively improves the overall radiation frequency and radiation efficiency of the antenna. In other words, the high-performance terminal antenna of this invention uses the feed point 1 and the ground point 2 to extend large-area main branches and couple them together, similar to a dipole antenna, achieving a very high intermediate frequency (IF) efficiency. The IF transmission efficiency can reach approximately -3.6 dB, fully meeting user requirements.
