The microphone 1042 can receive sounds (audio data) via the microphone 1042 in operating modes such as a phone call mode, a recording mode, a voice recognition mode, etc., and can process such sounds into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in the case of the phone call mode and output. The microphone 1042 can implement various types of noise cancellation (or suppression) algorithms to cancel (or suppress) the noise or interference generated during the reception and transmission of audio signals.

Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect touch operations of the user on or near it (such as operations of the user using a finger, a stylus or any suitable object or accessory on or near the touch panel 1071), and drive the corresponding connection device according to a preset program. The touch panel 1071 can include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the touch position of the user, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 110, and can receive and execute the commands sent by the processor 110. In addition, the touch panel 1071 can be implemented in multiple types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072.

Subsequently, the processor 110 provides a corresponding visual output on the display panel 1061 according to the type of the touch event. Although in Figure 1 the touch panel 1071 and the display panel 1061 are implemented as two independent components to realize the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the mobile terminal, and specific details are not limited here.

[0068] The mobile terminal 100 can also include a power supply 111 (such as a battery) for supplying power to each component. Preferably, the power supply 111 can be logically connected to the processor 110 through a power management system, so as to realize functions such as management of charging, discharging, and power consumption management through the power management system.

[0070] To facilitate the understanding of the embodiments of the present application, the communication network system on which the mobile terminal of the present application is based will be described below.

[0071] Please refer to Figure 2 , Figure 2 which is an architecture diagram of a communication network system provided by an embodiment of the present application. The communication network system is an LTE system of the general mobile communication technology. The LTE system includes a UE (User Equipment) 201, an E-UTRAN (Evolved UMTS Terrestrial Radio Access Network) 202, an EPC (Evolved Packet Core) 203, and the operator's IP service 204 that are sequentially communicatively connected.

[0072] Optionally, the UE 201 may be the aforementioned terminal 100, which will not be elaborated here.

[0073] The E-UTRAN 202 includes an eNodeB 2021 and other eNodeBs 2022, etc. Optionally, the eNodeB 2021 may be connected to other eNodeBs 2022 through a backhaul (such as an X2 interface), the eNodeB 2021 is connected to the EPC 203, and the eNodeB 2021 may provide access for the UE 201 to the EPC 203.

[0075] The IP service 204 may include the Internet, an intranet, an IMS (IP Multimedia Subsystem), or other IP services, etc.

[0076] Although the above has been introduced by taking the LTE system as an example, those skilled in the art should be aware that the present application is not only applicable to the LTE system, but also applicable to other wireless communication systems, such as GSM, CDMA2000, WCDMA, TD-SCDMA, 5G, and future new network systems (such as 6G), etc., which are not limited here.

[0077] Based on the above mobile terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0078] The first embodiment

[0079] Figure 3 Schematic diagram of the antenna architecture according to an embodiment of the present application Figure 1 , as Figure 3 shown, in this embodiment, the antenna includes:

[0080] A first process radio frequency section 1 and a second process radio frequency section 2, the first process radio frequency section 1 and the second process radio frequency section 2 are connected through a preset feeding terminal 3 for radio frequency coupling, so as to be commonly connected to a grounding terminal 5 to achieve common grounding.

[0081] An antenna is a transducer that converts the guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or performs the reverse conversion. It is a component used to transmit or receive electromagnetic waves in a radio device. In engineering systems such as radio communication, broadcasting, television, radar, navigation, electronic countermeasures, remote sensing, and radio astronomy, all of which use electromagnetic waves to transmit information, rely on antennas to work. In addition, in terms of transmitting energy with electromagnetic waves, non-signal energy radiation also requires an antenna. Generally, an antenna has reversibility, that is, the same antenna can be used as both a transmitting antenna and a receiving antenna. The basic characteristic parameters of the same antenna as a transmitter or a receiver are the same. This is the reciprocity theorem of the antenna.

[0082] An antenna radiates electromagnetic waves with a radio frequency radiation wire. Different manufacturing processes of the radio frequency radiation wire result in different radiation parameters. Exemplarily, when the length L of the radio frequency radiation wire is much smaller than the wavelength λ, the radiation is very weak; when the length L of the radio frequency radiation wire increases to be comparable to the wavelength, the current on the radio frequency radiation wire will increase greatly, and thus a stronger radiation can be formed. Utilizing this characteristic, by setting multiple process radio frequency sections on an antenna, more radiation effects can be achieved through radio frequency coupling.

[0083] In this embodiment, the first process radio frequency section and the second process radio frequency section are connected through a preset feeding terminal for radio frequency coupling to achieve common grounding, which can increase the clearance area of the intelligent terminal without changing the overall size of the machine, the antenna area can be reused maximally, reduce the area required for the antenna, and improve the antenna radiation efficiency.

[0084] Optionally, the first process radio frequency section 1 is an in-mold nano-injection molded antenna section.

[0085] Nano-injection molding is a high-precision injection molding technology with an accuracy reaching the micron level. Its principle is to add nano-scale powder during the injection molding process, making the molecular structure of the plastic material compact, thereby enhancing the strength and hardness of the material. Nano-injection molding is usually used to produce high-precision components, such as optical lenses, micro-devices, etc. In-mold injection molding, also known as injection molding, is a technology that injects molten plastic into a mold for shaping. The characteristic of in-mold nano-injection molding is that during the injection molding process, the contact area between the plastic material and the mold is very small, so it can produce very complex components. In-mold nano-injection molding is usually applied to the production of large quantities of plastic products, such as plastic shells, components with complex structures, etc. The cost of in-mold nano-injection molding is relatively low.

[0086] Optionally, the second process radio frequency section 2 is a laser direct structuring antenna section.

[0087] Laser Direct Structuring (LDS) antenna technology is laser direct structuring technology. It uses a computer to control the movement of a laser according to the trajectory of a conductive pattern, projects the laser onto a three-dimensional plastic device formed by molding, and activates a circuit pattern within a few seconds. Simply put (for mobile phone antenna design and production), on a formed plastic bracket, a metal antenna section is directly formed by laser plating using laser technology. Through laser direct structuring technology, the antenna can be directly laser engraved on the mobile phone shell.

[0089] Please refer to Figure 4 , optionally, the antenna further includes:

[0090] The preset feeding end includes a first feeding end 31 and a second feeding end 32.

[0091] Exemplarily, by setting different feeding ends, the antenna frequency can be adjusted by matching.

[0092] Optionally, the first process radio frequency section includes a first side excitation section 11 and a second side excitation section 12.

[0093] Exemplarily, the first process radio frequency section can excite wireless signals of different frequency bands by setting different excitation sections.

[0094] Optionally, the second process radio frequency section includes a first direction excitation section 21 and a second direction excitation section 22 which are set in common ground.

[0095] Exemplarily, the second process radio frequency section can excite wireless signals of different frequency bands by setting different excitation sections. The common ground setting can maximize the reuse of the antenna area and improve the radiation efficiency.

[0096] Optionally, the first side excitation section 11 excites the low frequency band.

[0097] Exemplarily, LTE (Long Term Evolution) is the long-term evolution of the UMTS (Universal Mobile Telecommunications System) technical standard formulated by the 3GPP (The 3rd Generation Partnership Project). The specification of LTE is called EPS (Evolved Packet System). LTE defines at least three frequency bands: LB is the low (frequency) band, MB is the middle (frequency) band, and HB is the high (frequency) band. In this embodiment, in LTE communication, the first side excitation section 11 is used to excite the low frequency band of 600 - 960 MHz to implement the LB mode.

[0098] Optionally, the second side excitation section 12 excites a preset frequency point.

[0099] Exemplarily, the second side excitation section 12 can be used to excite the frequency bands required for the satellite positioning system modes, such as the GPS, Beidou satellite, Glonass system and other modes.

[0100] Optionally, the first direction excitation section 21 excites the middle frequency band.

[0101] Exemplarily, in LTE communication, the first direction excitation section 21 can be used to excite the middle frequency band of 1800 - 2200 MHz to implement the MB mode.

[0102] Optionally, the second direction excitation section 22 excites the high frequency band.

[0109] Figure 5 It is a schematic diagram of a mobile phone antenna architecture according to an embodiment of the present application.

[0110] Please refer to Figure 5 , exemplarily, according to the above size limitations, the realized antenna has a small area, only about 160 mm2. The small antenna area ensures the antenna isolation and will not be affected by the mutual interference caused by the too close distance between antennas, greatly improving the user's communication and Internet experience. By limiting the specific size of the antenna, two antennas are combined into an antenna with an integrated design of four functional modules, saving the manufacturing cost and assembly cost of part of the antenna; without changing the frequency band requirements, it can achieve or exceed the original antenna performance by using less antenna area.

[0111] Please continue to refer to Figure 4 , optionally, the antenna further includes a switching switch 4 and a ground spring piece 6.

[0112] Exemplarily, it can be achieved by using two - stage MDA (In - Mold Nano - Injection) metal frames + LDS (Laser - Direct Structuring) traces. It can cover multiple frequency bands including low - frequency, medium - high - frequency, and high - frequency, and can increase the antenna bandwidth by adding switch - overs. Exemplarily, by adding a connection switch in the LB - mode excitation section, the first - process RF section can be flexibly grounded to switch the LB mode so that it covers more frequency bands (B5, B28, B8, B71, B20).

[0113] Optionally, the ground spring piece 6 is connected in series to the first - process RF section 11 through the switching switch 4. Optionally, the distance between the series - set switching switch and the ground spring piece and the feeding end is 7.8 mm.

[0114] Exemplarily, adding a ground spring piece can flexibly adjust the antenna frequency. The ground spring feet are in series with a switch, increasing the isolation between two antennas.

[0115] In the technical solution of this embodiment, through the first - process RF section and the second - process RF section, the first - process RF section and the second - process RF section are connected through a preset feeding end for RF coupling to achieve common grounding. Without changing the size of the whole machine, it can increase the clearance area of the intelligent terminal and reduce the area required for the antenna.

[0116] Second Embodiment

[0117] This application also provides an intelligent terminal, including the antenna described in any of the above embodiments.

[0118] Please refer to Figure 4 , in one embodiment, in the antenna installed in the intelligent terminal, the first - process RF section and the second - process RF section are connected through a preset feeding end for RF coupling to achieve common grounding. Without changing the size of the whole machine, it can increase the clearance area of the intelligent terminal, the antenna area can be maximally reused, reduce the area required for the antenna, and improve the antenna radiation efficiency.

[0119] Optionally, the intelligent terminal further includes a main board, a main - board bracket, and a metal frame. Optionally, the main board of the intelligent terminal is installed on the metal frame and the main - board bracket. Optionally, the first - process RF section of the intelligent terminal is arranged on the metal frame. Optionally, the main board of the intelligent terminal is connected to the first - process RF section. Optionally, the second - process RF section of the intelligent terminal is arranged on the main - board bracket. Optionally, the main board of the intelligent terminal is connected to the second - process RF section.

[0120] Exemplarily, please continue to refer to Figure 4 and Figure 5, the smart terminal in this embodiment uses two - section MDA (In - Mold Nano - Injection) metal frames + LDS (Laser - Direct - Structuring) traces to achieve the antenna structure, which can cover multiple frequency bands including low - frequency, medium - high - frequency, and high - frequency, and can increase the antenna bandwidth by adding switch switching. The length of the MDA (In - Mold Nano - Injection) metal frame is determined by simulation in the early stage to preferably meet the key frequency bands, and the LDS (Laser - Direct - Structuring) traces meet the remaining frequency bands. After the LDS (Laser - Direct - Structuring) of the two antennas is connected to the common ground, the antenna area can be reused to the maximum extent, and the radiation efficiency is improved. In this way, the areas of both ANT1 and ANT2 antennas can be utilized simultaneously in the current smart - terminal environment, and the LDS (Laser - Direct - Structuring) can effectively couple with the MDA (In - Mold Nano - Injection) metal frame to improve the antenna efficiency. Secondly, because the dual - feed common - ground scheme reuses the LDS (Laser - Direct - Structuring), the required area is smaller than that required for the traditional separate design of two antennas. Adding a ground spring in the middle can not only adjust the antenna frequency (the ground spring feet can be connected in series with a switch), but also increase the isolation between the two antennas. Adding a ground spring can adjust the antenna frequency, the ground spring feet can be connected in series with a switch, and the isolation between the two antennas can be increased.

[0121] Exemplarily, in the antenna installation of the smart terminal, the MDA (In - Mold Nano - Injection) antenna is installed on the metal frame, and the motherboard is installed. The gold fingers on the side contact the metal frame to achieve the antenna radiation effect. The LDS (Laser - Direct - Structuring) antenna is located on the motherboard bracket. When the motherboard bracket is installed, the gold fingers on the motherboard contact the LDS (Laser - Direct - Structuring) on the bracket to achieve the antenna radiation effect. In actual use, the frequency deviation generated by antenna resonance can be optimized through LDS (Laser - Direct - Structuring) or circuit matching debugging.
