[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this invention are used to explain the invention, but are not intended to limit the invention.

[0041] The term "comprising" and its variations as used herein signify open inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". The terms "first", "second", etc., may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0042] In the existing technology, because the antenna port of the 4G module is fixed, the antenna feed point is unique and corresponds to only one set of matching circuits. When the antenna bandwidth is limited, this matching can only be used for a certain frequency band. The use of this matching may make the already limited antenna bandwidth even narrower, affecting other frequency bands and thus reducing antenna performance.

[0043] To address the aforementioned problems, this embodiment provides an antenna module device, including:

[0044] A connecting line, which connects the antenna and the 4G module, is used to transmit the signal received by the antenna to the 4G module;

[0045] The processor is connected at one end to the 4G module and at the other end to multiple matching lines. The processor is used to receive signals transmitted by the 4G module and determine the connection of a certain matching line based on the signals transmitted by the 4G module.

[0046] Multiple matching lines are provided, each of which is connected at one end to the processor and at the other end to the antenna. The multiple matching lines are matched to multiple different frequency bands respectively. The multiple matching lines are used to connect according to the instructions of the processor to adjust the resonance of the antenna.

[0047] In this embodiment, the 4G module is equipped with an antenna port. One end of the connecting line is connected to the antenna, and the other end is connected to the antenna port of the 4G module. The antenna transmits the received signal to the 4G module through the connecting line. Generally, the antenna receives real-time information from the operator's base station.

[0048] The processor is typically a CPU, and the 4G module communicates with it via a USB interface. The 4G module transmits the received signal to the processor through the USB interface. The processor analyzes the signal to determine whether the antenna resonance needs adjustment, and if so, which matching line to use for adjustment. If the analysis determines the signal quality is good, no antenna resonance adjustment is needed. If the analysis determines the signal quality is poor, a corresponding instruction is generated to connect a specific matching line to adjust the antenna resonance.

[0049] This embodiment features multiple matching lines. The purpose is to match multiple different frequency bands, thereby adjusting the antenna resonance across these bands to improve antenna performance. The matching lines are connected to the processor via GPIO ports. These matching lines can be connected according to processor instructions. Each matching line in this embodiment may contain one or more matching circuits, and at any given time, only one matching circuit in one of the multiple matching lines is connected.

[0050] The antenna module device described in this embodiment can receive signals transmitted by the antenna in real time through connection lines, and the processor determines the signal quality. Based on the signal quality, it determines which matching line to connect to adjust the antenna resonance. Since any two matching lines correspond to different signal frequency bands, modifying any matching line in any frequency band will not affect other matching lines, thereby improving antenna performance.

[0051] In this embodiment, each of the plurality of matching lines includes: a first matching circuit, a first antenna switch, and a first feed point;

[0052] The first matching circuit is used to adjust the resonance of the antenna;

[0053] The control terminal of the first antenna switch is connected to the first matching circuit, the fixed terminal of the first antenna switch is connected to the first feed point, and the first antenna switch is connected to the processor via GPIO.

[0054] One end of the first feed point is connected to the fixed end of the first antenna switch, and the other end is connected to the antenna.

[0055] The first antenna switch is a single-pole single-throw switch or a single-pole multi-throw switch; wherein

[0056] If the first antenna switch is a single-pole single-throw switch, then the control terminal of the first antenna switch is connected to the first matching circuit, and the fixed terminal of the first antenna switch is connected to the first feed point.

[0057] If the first antenna switch is a single-pole multi-throw switch, then the multiple control terminals of the first antenna switch are respectively connected to multiple first matching circuits, and the fixed terminal of the first antenna switch is connected to the first feed point.

[0058] The first matching circuit is any one or more of the following: lumped parameter matching circuit, L-shaped matching circuit, T-shaped matching circuit, or π-shaped matching circuit.

[0059] Specifically, the first antenna switch has a GPIO port, and the processor also has a corresponding GPIO port. The first antenna switch and the processor are connected through their GPIO ports to allow the processor to send commands to the first antenna switch to connect / disconnect the corresponding first matching circuit. It should be noted that each first antenna switch may correspond to one first matching circuit (the first antenna switch is a single-pole single-throw switch) or multiple first matching circuits (the first antenna switch is a single-pole multi-throw switch). The first antenna switch can control the switching of different first matching circuits, where any two matching circuits match different frequency bands, allowing for adjustments to different antenna resonances to improve antenna performance.

[0060] Reference Figure 1 As shown, this includes multiple matching lines from matching line A to matching line N. However, this paper does not limit the number of matching lines to only AN. Figure 1 For example only, taking matching line A as an example, the first antenna switch A is a single-pole multi-throw switch that can connect the first matching circuit A1 to A2. n This paper does not limit the number of first matching circuits corresponding to a single-pole multi-throw switch to only 1-n; taking matching line N as an example, the first antenna switch N is a single-pole single-throw switch. Since for multiple matching lines, only one matching circuit of one matching line is connected at any given time, therefore... Figure 1 As shown, only the first matching circuit N in the matching line N is connected.

[0061] Reference Figure 2 , Figure 2 The first antenna switch A is a single-pole multi-throw switch. RF1 to RFN are multiple control terminals of the first antenna switch A. The multiple control terminals are connected to multiple first matching circuits respectively. COM is the fixed terminal of the first antenna switch A. The fixed terminal is connected to the first feed point. The first antenna switch A is connected to the processor through the GPIO port. Figure 2The state shown is when the RF1 terminal is connected. In this state, the first matching circuit connected to the RF1 terminal is turned on, thereby adjusting the antenna resonance.

[0062] In this embodiment, the connection line includes: a second matching circuit, a second antenna switch, and a second feed point;

[0063] One end of the second matching circuit is connected to the 4G module, and the other end is connected to the second antenna switch. The second matching circuit is used to adjust the impedance of the connection line.

[0064] One end of the second antenna switch is connected to the second matching circuit, and the other end is connected to the second feed point;

[0065] One end of the second feed point is connected to the second antenna switch, and the other end is connected to the antenna.

[0066] The second matching circuit is any one or more of the following: lumped parameter matching circuit, L-shaped matching circuit, T-shaped matching circuit, or π-shaped matching circuit.

[0067] In order to continuously receive signals from the antenna, the connection line is kept in a connected state, that is, the second antenna switch is kept in a closed state. The second antenna switch is equipped with a GPIO port, and the processor is also equipped with a corresponding GPIO port. The second antenna switch and the processor are connected through the GPIO port between them, so that the processor can control the connection line to be connected or disconnected.

[0068] It should be noted that the function of the second matching circuit is to adjust the impedance of the connection line. Specifically, there may be mismatches in the routing of the connection line, which will affect the signal transmission. In this case, it is necessary to adjust the impedance of the connection line through the second matching circuit to ensure that the impedance in the connection line is 50 ohms and improve the signal transmission efficiency.

[0069] Reference Figure 1 As shown, this embodiment includes only one connection line, in which the second antenna switch remains closed so that the 4G module can receive the signal transmitted by the antenna in real time.

[0070] In this embodiment, the second feed point is the main antenna feed point, and the first feed point is the ground feed point, such as... Figure 1 As shown, the first feed point A to the first feed point N are ground feed points.

[0071] Based on the above antenna module equipment, refer to Figure 3 This embodiment also provides an antenna tuning method, which is applied to a processor and includes:

[0072] S101: Receive the signal transmitted by the 4G module as the signal for the current time period;

[0073] S102: Compare the signal of the current time period with the signal of the previous time period to determine the adjustment frequency band corresponding to the antenna;

[0074] S103: Based on the adjusted frequency band, determine the matching line that matches the adjusted frequency band and generate an instruction;

[0075] S104: Send the instruction to the corresponding matching line.

[0076] Generally, 4G modules receive information from operator base stations in real time via antennas. Specifically, the 4G module sends network registration information (network type, frequency band, channel) and the corresponding cell's RSSI to the processor. The processor compares the received network registration information and RSSI with the previously received information and determines whether to perform an antenna switching operation to switch the matching line based on the network priority and the comparison of the RSSI values.

[0077] Based on the above antenna module equipment, refer to Figure 4 This embodiment also provides an antenna tuning method, which is applied to a matching line, including:

[0078] S201: Receive the instruction sent by the processor;

[0079] S202: Connect the corresponding circuit according to the instruction to adjust the resonance of the antenna.

[0080] Since any matching line may correspond to one or more first matching circuits, in S202, according to the instruction, only one of the first matching circuits in a matching line is connected to adjust the resonance of the antenna.
