Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The application scenario described in the embodiment of the present invention is for more clearly illustrating the technical solution of the embodiment of the present invention, and does not form a limitation on the technical solution provided in the embodiment of the present invention, and it can be known by a person skilled in the art that with the occurrence of a new application scenario, the technical solution provided in the embodiment of the present invention is also applicable to similar technical problems. In the description of the present invention, the term "plurality" means two or more unless otherwise specified.
The 3G antenna or the 4G antenna of the current intelligent terminal comprises a main antenna and a diversity antenna, wherein the main antenna comprises a double-frequency transceiving function, the diversity antenna mainly assists the main antenna to carry out multipath reception, and the functions of the main antenna and the diversity antenna can be interchanged under special conditions. The frequency bands supported by the main antenna and the diversity antenna are many, and generally, one antenna includes a low frequency (below 1 GHz), an intermediate frequency (1-2 GHz) and a high frequency (2-2.5 GHz), so an antenna tuner is used in conventional antenna debugging. The antenna tuner changes the impedance value of a circuit connected with the antenna through a plurality of switches, so that the frequency band supported by the antenna is changed, the antenna cannot work at low frequency, medium frequency and high frequency simultaneously, and only works at a single frequency band at the same time. When the intelligent terminal is in a standby state, the intelligent terminal cannot stay in any frequency band, and the antenna tuner is powered off (in an open circuit state). When the antenna is switched to different frequency bands, the impedance value of the antenna slightly changes, but when the antenna is switched from an operating state to a non-operating state, the impedance value of the antenna greatly changes.
When the intelligent terminal antenna is designed, the main antenna and the diversity antenna use the antenna tuner, the GPS antenna and the WIFI antenna do not need to use the antenna tuner, in hardware design, the main antenna is usually arranged at the bottom of the intelligent terminal, other antennas do not exist around the main antenna, the diversity antenna is arranged at the top of the intelligent terminal, the GPS antenna and the WIFI antenna usually exist around the diversity antenna, the space distance between the two antennas is very short, as shown in figure 1, the antenna setting schematic diagram of the intelligent terminal with the metal frame is shown, in the scheme of the metal frame antenna, because the GPS antenna and the diversity antenna both use the upper frame, only 1.5mm of space exists in the middle, the isolation between the two antennas is very poor, and therefore a very strong parasitic effect is formed.
Assuming that the main antenna or the diversity antenna is an a antenna, there are usually additional B antennas and C antennas (such as GPS antennas and WIFI antennas) beside them, and when the a antenna operates in different frequency bands, the impedance state of the a antenna itself is different due to different matching values connected to the antenna tuner. In the prior art, when an antenna is debugged, an impedance state of an antenna A is usually fixed, and then the performance of an antenna B is debugged, so that the performance of the antenna A and the performance of the antenna B are optimal at the same time.
Therefore, when the diversity antenna is operated, the performance of other nearby antennas such as the GPS antenna is better, but when the smart terminal is in a standby state, the diversity antenna is not operated, and the performance of other nearby antennas such as the GPS antenna is seriously deteriorated.
In order to solve the above problems, in the prior art, a commonly adopted solution is to increase the distance between two antennas as much as possible, increase isolation, reduce coupling parasitic effect between the antennas, and weaken the influence of the working state change of the antennas on the performance of other antennas.
Based on the above problems, embodiments of the present application provide a mobile terminal device and a multi-antenna debugging method, where the mobile terminal device may be a mobile terminal device with built-in multi-antenna, such as a mobile phone, a tablet computer, a wearable device, and a notebook computer.

When the first antenna circuit is switched to a non-working state and all the second antenna circuits are in the non-working state of stopping receiving and sending signals, the power of the antenna tuner is controlled to be powered off through the main control chip, and therefore the power consumption of the mobile terminal device can be saved.
Mode two, the first antenna circuit is in a non-working state and the second antenna circuit is in a working state

step S302, if yes, adjusting an impedance value of the first antenna circuit by the antenna tuner, so that a performance index of the second antenna reaches a preset requirement.
And when the first antenna circuit is in a non-working state and all the second antennas are determined to be in a non-working state for stopping transmitting and receiving signals, controlling the antenna tuner to be powered down.

As a specific implementation manner, in the embodiment of the present application, the switching of the antenna tuner in different matching states is realized by three control signals (CTRL), which is mainly realized by switching a single-pole multi-throw switch to one or more of RF 1-RF 4. Fig. 4 is a schematic diagram showing the operation of the second antenna, the first antenna circuit and the corresponding antenna tuner.
As shown in table 1, for the configuration table of the antenna tuner:
TABLE 1
| CTRL1 | CTRL2 | CTRL3 | RFC | First antenna frequency band |
| 0 | 0 | 1 | All On | Free up |
| 0 | 1 | 1 | RF1&RF2 | B1/B5/B34 |
| 1 | 0 | 0 | RF3&RF4 | Free up |
| 0 | 0 | 0 | RF1 | B7/B38/B41 |
| 0 | 1 | 0 | RF2 | Free up |
| 1 | 0 | 0 | RF3 | B8 |
| 1 | 1 | 0 | RF4 | Second antenna |
| 1 | 1 | 1 | All Null | B20/B26 |
As shown in fig. 4 and table 1, when the first antenna circuit operates in one of the frequency bands B1/B5/B34, the antenna tuner is powered on (VDD is 1.8V), and its control signal logic is 011(CTRL1 is 0, CTRL2 is 1, CTRL3 is 1), at this time, the internal switches of the tuner are switched to RF1 and RF2 at the same time, that is, the corresponding matching circuits are a capacitor C1 and an inductor L1, and then the performance of the first antenna circuit is optimized by adjusting the values of the capacitor C1 and the inductor L1; when the diversity antenna operates in the B8 frequency band, the logic of the control signal of the antenna tuner is 100, and the inside of the antenna tuner is switched to RF3, and the corresponding matching circuit is C2.
