Technical field

Background technique

At present, mobile terminals such as mobile phones have become an indispensable consumer electronics in daily life. With the rapid development of electronic communication technologies, mobile terminals have more and more functions, and more and more communication methods are being used. With the increasing communication demand, the current development trend of antenna technology is that the number of antennas is increasing, the data speed is getting faster and faster, and the response speed of mobile phones is getting faster and faster. For example, in order to improve the efficiency of signal transmission and reception, multiple input and multiple technologies ( Multiple-Input Multiple-Output (MIMO) technology has received more and more favor. MIMO technology uses multiple antennas to simultaneously transmit and receive signals, which can double the communication rate. At present, 4*4 MIMO technology has begun to take off globally. With the development of 4.5G technology, 4*4 MIMO is about to enter the commercial stage, and the future 5G communication is the demand of 8*8 MIMO.

However, since the frequency band of the antenna for transmitting and receiving signals corresponds to its electrical length, signals transmitting and receiving different frequency bands need to be provided with antennas of different electrical lengths, and each antenna needs to occupy a certain mobile phone space, which is limited by the size of the mobile phone, and the internal of the mobile phone The number of antennas that can be accommodated is limited. For example, the size of a normal mobile phone is about 15cm long and 7cm wide, and the length of a normal mobile phone antenna is comparable, for example, the frequency of LTE B8 (a radio frequency band). From 925Mhz to 960Mhz, the free-space wavelength λ is about 33cm, the antenna wavelength λ/4 is about 8cm, and the mobile phone has a dielectric constant of 1.7, and the antenna is made up of a minimum of 8cm in the mobile phone.

About 5cm, there are about 10 RF bands that need to be supported in mobile phones, and 10 antennas should be set accordingly. The implementation of MIMO technology requires more antennas in mobile phones. The compact mobile phone space presents even more serious challenges.

In summary, the related technology has the following technical problems: due to the limitation of mobile phone space, it is difficult to set more antennas in the mobile phone to meet the requirements of MIMO technology.

Detailed ways

In order to make those skilled in the art better understand the technical solutions in the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the drawings in the embodiments of the present disclosure. The embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope should fall within the scope of the disclosure.

In the embodiment of the present disclosure, the mobile terminal is a terminal device having a wireless communication function, including but not limited to a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a vehicle-mounted terminal, a wearable device, and the like. Be explained.

Considering that the antennas of multiple frequency bands set in a mobile terminal (for example, a mobile phone) usually do not work at the same time, in most cases, only one or a few antennas simultaneously transmit and receive signals at the same time. Other antennas are idle. If these idle antennas can be utilized and the MIMO system is formed with the working antenna, the limitation of the number of antennas in the mobile phone space can be removed, making it possible to implement the MIMO system with fewer antennas.

The present disclosure provides an antenna device and a mobile terminal, and an embodiment of the present disclosure will be described below with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of a first structure of an antenna device according to an embodiment of the present disclosure. As shown in FIG. 1 , the antenna device includes at least:

a first antenna 11, a second antenna 12, a first feed 31, a second feed 32, and a single pole double throw switch 21;

The first antenna 11 is connected to the first feed 31;

The second antenna 12 is selectively connectable to the second feed source 32 or to the first antenna 11 by the single-pole double-throw switch 21 described above. In a specific implementation, the movable end 211 of the single-pole double-throw switch 21 is connected to the second antenna 12, and the first fixed end 212 of the single-pole double-throw switch 21 is connected to the first antenna 11, and the single-pole The second fixed end 213 of the double throw switch 21 is connected to the second feed source 32;

When the single-pole double-throw switch 21 is turned off, the first feed source 31 transmits and receives a signal of a first frequency;

When the movable end 211 of the single-pole double-throw switch 21 is closed and the first fixed end 212 is closed, the first antenna 11 and the second antenna 12 are connected in series to form a third antenna, and the first feed 31 transmits and receives a signal of a third frequency. ;

When the movable end 211 and the second fixed end 213 of the single-pole double-throw switch 21 are closed, the first feed 31 transmits and receives a signal of a first frequency, and the second feed 32 transmits and receives a signal of a second frequency.

Since the frequency of the antenna transceiver signal is inversely related to the electrical length of the antenna itself, the embodiment of the present disclosure may be configured to set a single-pole double-throw switch 21 and the first low-frequency antenna for transmitting and receiving low-frequency signals in the mobile terminal. a second feed 32, the second fixed end 213 of the single-pole double-throw switch 21 is connected to the second feed 32, such that when the movable end 211 and the second fixed end 213 of the single-pole double-throw switch 21 are closed, The original low frequency antenna is divided into the first antenna 11 and the second antenna 12 which can work independently, and can switch the original low frequency antenna to an intermediate frequency antenna for transmitting and receiving an intermediate frequency signal, and/or for transmitting and receiving a high frequency signal. The high frequency antenna, that is, the original low frequency antenna can be switched to a high frequency antenna and/or an intermediate frequency antenna when it does not need to work.

Similarly, when the embodiment of the present disclosure is implemented, the first antenna 11 may be a high frequency antenna for transmitting and receiving high frequency signals in the mobile terminal, or an intermediate frequency antenna for transmitting and receiving an intermediate frequency signal, and the second antenna 12 is a high frequency antenna for transmitting and receiving a high frequency signal in the mobile terminal, or an intermediate frequency antenna for transmitting and receiving an intermediate frequency signal, by providing a single pole double throw switch between the first antenna 12 and the second antenna 12, the single pole double throw The movable end 211 of the switch 21 is connected to the second antenna 12, and the first fixed end 212 of the single-pole double-throw switch 21 is connected to the first antenna 11, so that when the movable end 211 of the single-pole double-throw switch 21 is When the fixed end 212 is closed, the first antenna 11 and the second antenna 12 can be connected in series to form a third antenna having a longer electrical length. Since the frequency of the antenna transceiving signal is inversely related to the electrical length of the antenna itself, The third antenna can be used for transmitting and receiving low frequency signals, thereby switching the original two intermediate frequency antennas or the high frequency antennas of the first antenna 11 and the second antenna 12 into low frequency antennas for transmitting and receiving low frequency signals, that is, this When the original high-frequency antenna and / or intermediate frequency antenna does not work, it can be switched to the low frequency antenna.

In the embodiment provided by the present disclosure, the signals of the first frequency, the second frequency, and the third frequency can be sent and received by using the two antennas of the first antenna 11 and the second antenna 12, which are separately configured according to related technologies. When three antennas transmit and receive signals of three frequencies of the first frequency, the second frequency, and the third frequency, by multiplexing the first antenna 11 and the second antenna 12, the number of antennas can be effectively reduced, and the overall occupation of the antenna device can be reduced. The space makes it possible to set more antennas in the limited space of the mobile phone and send and receive signals of more frequency bands, which is beneficial to the realization of the MIMO system.

For example, the first antenna 11 may be a high frequency antenna (the frequency range of the high frequency in the embodiment of the present disclosure may be 2.3-2.7 GHz), and the second antenna 12 may be an intermediate frequency antenna. (The frequency range of the intermediate frequency in the embodiment of the present disclosure may be 1.71. - 2.17 GHZ), the first antenna 11 and the second antenna 12 can be combined to form a low frequency antenna (the frequency range of the low frequency in the embodiment of the present disclosure may be 0.7-0.96 GHz), since the electrical length of the high frequency antenna is smaller than that of the intermediate frequency antenna. Length, and the electrical length of the intermediate frequency antenna is smaller than the electrical length of the low frequency antenna. Therefore, based on the present embodiment, two shorter high frequency antennas and intermediate frequency antennas can be utilized to realize signal transmission and reception in three frequency bands of high frequency, intermediate frequency and low frequency. Compared with the related art, the three antennas of the high frequency antenna, the intermediate frequency antenna and the low frequency antenna respectively transmit and receive signals of three frequency bands of high frequency, intermediate frequency and low frequency, which can save one longest low frequency antenna, and the whole antenna device can be Save about half of the occupied space, making it possible to transmit and receive signals in more frequency bands with fewer antennas in a limited space of the mobile phone, contributing to MIMO Construction of the system.

It is easy to understand that, because the frequency of the antenna transmitting and receiving signals is inversely related to the electrical length of the antenna itself, in the embodiment of the present disclosure, the electrical length of the third antenna is greater than the electrical length of the first antenna and greater than the electrical power of the second antenna. The length, the first frequency and the second frequency are both greater than the third frequency.

In a modified embodiment of the embodiment shown in FIG. 1, the electrical length of the first antenna 11 is equal to the electrical length of the second antenna 12;

When the movable end 211 and the second fixed end 213 of the single-pole double-throw switch 21 are closed, the first antenna 11 and the second antenna 12 form a multiple-input and multi-out antenna of the second frequency, that is, 2×2 MIMO constituting the second frequency signal. system.

For example, the first antenna 11 and the second antenna 12 may each be a high frequency antenna, and the electrical lengths of the two antennas may be equal. Thus, the first antenna 11 and the second antenna 12 may constitute a high frequency signal MIMO system, during operation, if The mobile terminal needs to send and receive a low frequency signal, and the movable end 211 of the single-pole double-throw switch 21 and the first fixed end 212 can be controlled to be closed. At this time, the first antenna 11 and the second antenna 12 are connected to form a third antenna for transmitting and receiving low-frequency signals. If the mobile phone needs to turn on the MIMO system of the high frequency signal, the movable end 211 and the second fixed end 213 of the single-pole double-throw switch 21 can be controlled to be closed. At this time, the first antenna 11 and the second antenna 12 respectively work independently. Both transmit and receive high-frequency signals, which can form a 2×2 MIMO system with high-frequency signals.

It is easy to understand that in the related art, more mobile phones start to use the diversity antenna technology, that is, the main set antenna and the diversity antenna are respectively set in the mobile phone, and both adopt the same antenna design, thereby forming a 2×2 MIMO system, and if the main Both the set antenna and the diversity antenna include the above embodiments, so that the 4×4 MIMO system for the second frequency signal can be realized, and the throughput and signal transceiving efficiency for the second frequency signal are further improved.

It is considered that the main antenna in the mobile phone is often designed with a multi-frequency antenna to receive signals of different frequency bands.

When the movable end 211 of the single-pole double-throw switch 21 is closed and the first fixed end 212 is closed, the first antenna 11 and the second antenna 12 form a third antenna, and the fourth antenna 14 and the third antenna form a second multi-frequency antenna;

When the movable end 211 and the second fixed end 213 of the single-pole double-throw switch 21 are closed, the fourth antenna 14 and the second antenna 12 form a multiple-input and multi-out antenna of the second frequency, that is, 2×2 MIMO constituting the second frequency signal. system.

Further, considering that the fourth antenna 14 and the first antenna 11 are connected to the same feed source, in order to prevent the fourth antenna 14 from working simultaneously with the first antenna 11, mutual interference occurs, and isolation between the two antennas is improved. Preferably, the electrical length of the fourth antenna 14 is not equal to the electrical length of the first antenna 11.

It can be seen that, in this embodiment, three antennas of the first antenna 11, the second antenna 12, and the fourth antenna 14 are used, which can constitute two multi-frequency antennas of the first multi-frequency antenna and the second multi-frequency antenna, and can also form a second frequency. The MIMO system of signals has high antenna utilization efficiency and flexibility of setting.

It is considered that in the related art, the main antenna often adopts a multi-frequency antenna design. For the sake of simple description, the embodiment of the present disclosure is summarized as a multi-frequency antenna including a high frequency antenna, an intermediate frequency antenna, and a low frequency antenna, wherein the low frequency antenna often does not The HF antenna and the IF antenna work at the same time. Therefore, in combination with the foregoing embodiments of the present disclosure, the low frequency antenna portion can be modified to implement multiplexing of the antenna.

The electrical length of the fourth antenna 14 is not equal to the electrical length of the first antenna 11, and the electrical power of the fourth antenna 14 is The length is equal to the electrical length of the second antenna 12, the electrical length of the fifth antenna 15 is greater than the electrical length of the second antenna 12, and the electrical length of the fifth antenna 15 is less than the sum of the electrical lengths of the second antenna 12 and the first antenna 11;

The movable end 211 of the single-pole double-throw switch 21 is connected to the second antenna 12, the first fixed end 212 of the single-pole double-throw switch 21 is connected to the first antenna 11, and the second fixed end 213 of the single-pole double-throw switch 21 is The two feeds 32 are connected.

An additional switch is provided in 31. When the MIMO system with high frequency signal or intermediate frequency signal is enabled, the switch is turned off to avoid isolation problem.
