[0052] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0053] On the one hand, combined with Figure 1 As shown, this embodiment provides an antenna tuner, including: a package body 1; at least one adjustable element 11 is integrated in the package body 1, and the electrical characteristics of the at least one adjustable element 11 are adjustable; the package body 1 is provided with at least one input port 12 and at least one output port 13, and the at least one adjustable element 11 is electrically connected between the at least one input port 12 and the at least one output port 13. The electrical characteristics of the adjustable element 11 include but are not limited to capacitance, inductance and resistance.

[0054] The antenna tuner of the utility model has at least one adjustable element 11 with adjustable electrical characteristics integrated in the packaging body 1. The adjustable element 11 is electrically connected between the input port 12 and the output port 13. By adjusting the electrical characteristics of the adjustable element 11, the power-on state between the input port 12 and the output port 13 can be changed, so that the antenna tuner exhibits a variety of different tuning states, thereby increasing the number of tuning states of the antenna tuner, and the antenna tuner can meet more antenna usage scenarios.

[0055] In some embodiments, the adjustable element 11 includes at least one of an adjustable capacitor, an adjustable resistor, and an adjustable inductor. The adjustable capacitor includes a MOS capacitor and a pn junction capacitor that can be applied to an integrated circuit. The adjustable capacitor is an electronic component produced using multi-layer pressing and packaging technology, and has the characteristics of small size, light weight, low cost, and long life.

[0056] For example, the adjustable capacitor is composed of a metal-oxide-semiconductor (MOS) structure, and the capacitance function is realized by using the capacitance effect formed between the metal layer and the semiconductor substrate. By changing the voltage between the metal electrode and the semiconductor substrate in the MOS structure, the capacitance value formed can be adjusted, and the capacitance value can be adjusted by tens or hundreds of times.

[0057] In another exemplary embodiment, the adjustable resistor is a variable resistor component whose resistance value can be adjusted by an external control signal. There are two types of adjustable resistors: Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) structure and Bipolar Junction Transistor (BJT) structure. The MOSFET structure adjusts the channel resistance by changing the gate voltage; the BJT structure adjusts the collector-emitter resistance by changing the base current.

[0058] In another exemplary embodiment, the adjustable inductor has an inductance function, and its inductance value can be adjusted by an external control signal. A spiral or parallel strip coil structure is used, and the inductance effect of the coil itself is used to realize the inductance function. The inductance value is adjusted by changing the current intensity inside the coil or the coil structure parameters, such as switching part of the coil.

[0059] Combination Figure 2As shown, in some embodiments, the antenna tuner further includes a control module 2, the control module 2 is electrically connected to at least one adjustable element 11, and the control module 2 is used to control the adjustment of the electrical characteristics of the at least one adjustable element 11. By controlling the electrical characteristics of the adjustable element 11 by the control module 2, the power-on state between the input port 12 and the output port 13 can be achieved, thereby achieving tuning of the antenna tuner.

[0060] Combination Figure 3 As shown, in some embodiments, the control module 2 includes a register unit 21, and the register unit 21 is electrically connected to at least one adjustable element 11. A plurality of control instructions are stored in the register unit 21. When the register unit 21 receives a corresponding external signal, it outputs a corresponding control instruction to the adjustable element 11 according to a preset mapping relationship, and the adjustable element 11 adjusts its own capacitance value, inductance value or resistance value in response to the control instruction.

[0061] For example, the adjustable range of the electrical characteristics of the adjustable element 11 is 0-X, and it is controlled by the 8-bit register unit 21. The register unit 21 can store 2^8 (i.e., 256) control instructions, and the adjustment step of the adjustable element 11 is X / 258. That is, the input port 12 and the output port 13 have 256 power-on states, which can theoretically enable the antenna tuner to achieve 256 tuning states.

[0062] Combination Figure 4 As shown, in some embodiments, at least one first switching element 14 is integrated in the package body 1, and the package body 1 is also provided with at least one ground port 15; at least one first switching element 14 is electrically connected between at least one ground port 15 and at least one output port 13 electrically connected to at least one adjustable element 11.

[0063] Through the above arrangement, the ground port 15 can provide a reference level for the entire antenna tuner, ensuring that the levels of each functional module inside the package body 1 are measured and controlled relative to the same reference level. This helps to ensure stable operation between the functional modules inside the antenna tuner.

[0064] By using the first switch element 14 to ground the output port 13 connected to the adjustable element 11 in parallel, the parasitic effects generated when the adjustable element 11 is working can be reduced, and the adjustable element 11 and the capacitor and inductor in the circuit can be prevented from forming a resonant circuit, resulting in high-frequency oscillation and high-frequency noise, which will affect the stability and performance of the circuit.

[0065] In addition, the ground port 15 also helps to dissipate heat for the antenna tuner. The heat of the package body 1 is transferred to the PCB (Printed Circuit Board) through the ground port 15, and then the heat is dissipated into the surrounding air through the heat dissipation structure on the PCB. The ground port 15 can also be used to shield interference signals and lead external electromagnetic noise to the ground to reduce interference with the internal circuit of the package body 1. The ground port 15 can also provide electrostatic protection for the antenna tuner, release static electricity to the ground, and prevent static electricity from damaging the internal circuit of the package body 1.

[0066] Combination Figure 5 As shown, in some embodiments, at least one second switching element 16 is also integrated in the package body 1, and the number of output ports 13 is at least two; wherein at least one output port 13 is electrically connected to at least one input port 12 through at least one adjustable element 11; and at least one output port 13 is electrically connected to at least one input port 12 through at least one second switching element 16.

[0067] By arranging the second switch element 16 between other output ports 13 and input ports 12, the second switch element 16 can be used to control the on-off of the circuit between the corresponding output port 13 and input port 12, thereby realizing the switching of the tuning state of the antenna tuner.

[0068] Combination Figure 6 As shown, in some embodiments, the package body 1 is further provided with at least one control port 17, and the control port 17 is electrically connected to at least one adjustable element 11. The antenna tuner can use the control port 17 to connect to an external communication system or other control system to control the adjustable element 11, so that the antenna tuner switches to a tuning state that meets the communication requirements of the communication system.

Through the above arrangement, the package body 1 conforms to the conventional shape of the chip structure, and the positions of the input port 12 and the output port 13 conform to the circuit layout of the existing electronic system, which is conducive to improving the versatility and adaptability of the antenna tuner of this embodiment in the existing electronic system.

[0070] Exemplarily, the number of output ports 13 is four, and the four output ports 13 are symmetrically arranged in groups of two on the second edge 102 and the third edge 103. Figure 1 As shown, the package body 1 is further provided with an addressing port 18, which is used to implement addressing and identification of the antenna tuner by the antenna system, and the addressing port 18 is located on the second edge 102 or the third edge 103. For example, the addressing port 18 and the grounding port 15 are symmetrically arranged on the second edge 102 and the third edge 103, respectively.

[0071] In another exemplary embodiment, the number of the output ports 13 is five, wherein three output ports 13 are arranged on the second edge 102 , and two output ports 13 are arranged on the third edge 103 .

[0072] In some possible implementations, reference Figure 1 The control port 17 is located at the fourth edge 104 of the package body 1. The control port 17 includes a power pin 171 (vio), a data transmission pin 172 (data) and a clock pin 173 (clk). The power pin 171 is configured to provide I / O power, the data transmission pin 172 is configured to transmit data information, the data information is a converted digital signal, and can be transmitted in serial or parallel mode. The clock pin 173 is configured to provide a clock signal, which is a clock signal of digital-to-analog conversion and can be provided by an internal clock source or an external clock source.

[0073] On the other hand, combined Figure 7 As shown, this embodiment provides an antenna assembly, including the antenna tuner of the utility model, as well as the antenna 3 and the communication module 4; the communication module 4 is electrically connected to the antenna 3 and the input port 12 respectively. The terminal device of this embodiment adopts the antenna tuner of the utility model, and has all the beneficial technical effects of all the embodiments of this invention. The antenna assembly can increase the number of tuning states by using the adjustable element 11, and can meet the communication needs of more communication modules.
