Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

In the related art, when the head and hand contact the antenna module, the impedance of the antenna module generates a frequency offset or most of energy radiated outwards is absorbed, such as "dead hold", so that the performance of the antenna module is reduced when the mobile phone is used. The conventional method generally adopts a mode of combining a middle frame antenna and a laser direct structuring (Laser Direct Structuring, LDS) antenna to reduce the influence of a head and a hand on an antenna module. However, adding an LDS antenna to a mobile terminal not only increases the LDS antenna material, resulting in an increase in design complexity and occupation area of an electronic device, but also causes mutual interference between different devices due to a high stacking degree of the devices.

Based on this, the embodiment of the disclosure provides an antenna module, which can improve the performance of the head and the hand without introducing additional devices. Fig. 1 is a schematic diagram illustrating a structure of an antenna module in a mobile terminal according to an exemplary embodiment. As shown in fig. 1, the antenna module includes:

a first conductive branch 101;

a second conductive branch 102 connected to the first conductive branch 101;

a feeding point 103 located on the first conductive branch 101;

when the antenna module transmits a wireless signal, the radiation current density of the first conductive branch 101 is smaller than that of the second conductive branch 102.

In the embodiment of the disclosure, the antenna module can be applied to a mobile terminal, and the antenna module is used for receiving and transmitting wireless signals so as to realize communication interaction between the mobile terminal and other devices. The mobile terminal comprises a smart phone, other devices comprise smart home devices (such as a smart sound box), and the smart phone can communicate with the smart sound box through the antenna module to control the smart sound box to output audio signals; or, the mobile terminal and other devices comprise smart phones, and the two smart phones perform voice call, video call or information transmission and the like through the antenna module.

The first conductive branch and the second conductive branch may be made of a metal material and/or an alloy material, which is not limited in the embodiments of the present disclosure.

In an embodiment of the disclosure, an included angle is formed between the first conductive branch and the second conductive branch, and the included angle is in a range of 0 degrees to 180 degrees. Illustratively, the included angle may be 90 degrees, i.e., the first conductive branch is perpendicular to the second conductive branch.

The shape of the first conductive branch and the shape of the second conductive branch can be strip-shaped. Here, the antenna module is applied to a mobile terminal. The first conductive branch and the second conductive branch can be used as a conductive frame of the mobile terminal and can be arranged on the inner side of the conductive frame of the mobile terminal, and the embodiment of the disclosure is not limited to this.

The length of the first conductive branch and the length of the second conductive branch can be set according to the frequency of the wireless signal transmitted and received by the antenna module. For example, the greater the frequency of the antenna module for receiving and transmitting the wireless signal, the smaller the lengths of the corresponding first conductive branch and the second conductive branch can be correspondingly set. In some embodiments, the second conductive branch is a bar-shaped conductive branch having a length in a range of 35 millimeters to 45 millimeters. In other embodiments, the first conductive branch may be configured to be greater than or equal to the second conductive branch.

In this disclosed embodiment, the first conductive branch is connected to the second conductive branch, and is used for receiving and transmitting wireless signals in the same frequency band, and the frequency of the receiving and transmitting wireless signals can be set according to actual requirements. In some embodiments, the frequency of the antenna module for receiving and transmitting wireless signals is in the range of 700MHz to 1280 MHz.

The feed point is located on the first conductive branch. The feed point can transmit a first electrical signal to the first conductive branch to excite the first conductive branch and the second conductive branch to transmit and receive wireless signals; the feeding point can also transmit a second electric signal obtained based on the conversion of the first conductive branch and the second conductive branch, and transmit the second electric signal to the radio frequency module.

Wherein, the radio frequency module includes: a first amplifier, an antenna switch, a filter, a diplexer and a second amplifier. The first amplifier is used for amplifying the first electric signal in the signal output channel. The antenna switch is used for realizing the switching between the receiving of the second electric signal and the transmitting of the first electric signal and the switching between different frequency bands of the antenna. The filter is used for filtering signals outside the specific frequency band through the signals of the specific frequency band. The duplexer is used for isolating the transmitted first electric signal and the received second electric signal, so that the antenna module can work normally when receiving and transmitting wireless signals simultaneously. The second amplifier is used for amplifying a second electric signal of the signal receiving channel. Therefore, the radio frequency module can be used for receiving the second electric signal and transmitting the first electric signal, so that the antenna module can be used for receiving and transmitting the wireless signal better.

In the embodiment of the disclosure, when the antenna module transmits a wireless signal, radiation current is formed on the first conductive branch and the second conductive branch, and the radiation current density of the first conductive branch is smaller than that of the second conductive branch. That is, the antenna radiation energy of the antenna module is concentrated at the second conductive branch. So, can reduce antenna module and receive the interference of head and hand under the condition that first electrically conductive minor matters were sheltered from by head and hand, and then can reduce antenna module's first electrically conductive minor matters and be sheltered from the sensitivity, can improve antenna module's radiant efficiency for the user can obtain better communication experience. In addition, according to the embodiment of the disclosure, through changing the radiation current density distribution condition of the antenna module, additional metal components are not required to be introduced, the stacking of the components can be reduced, the circuit structure is simplified, the occupied space of the antenna module can be reduced, and the space utilization rate is improved.

Fig. 2 is a schematic diagram illustrating radiation current simulation of an existing antenna module when the phase of an ac signal is 0 degrees according to an exemplary embodiment; fig. 3 is a schematic diagram illustrating radiation current simulation of a conventional antenna module when the phase of an ac signal is 90 degrees according to an exemplary embodiment. As shown in fig. 2 and fig. 3, the junction between the first conductive branch 101 and the second conductive branch 102 in the existing antenna module and the radiation current density of the first conductive branch 101 are large, so that the antenna radiation energy of the existing antenna module is mainly concentrated on the first conductive branch 101, and the antenna radiation energy is radiated through the break seam beside the first conductive branch 101, so that the radiation efficiency of the antenna module is reduced when the first conductive branch 101 is blocked.

In contrast, fig. 4 is a schematic diagram illustrating radiation current simulation of the antenna module of the present disclosure when the phase of the ac signal is 0 degrees according to an exemplary embodiment; fig. 5 is a schematic diagram illustrating radiation current simulation of the antenna module of the present disclosure when the ac signal phase is 90 degrees according to an exemplary embodiment. As shown in fig. 4 and 5, the radiation current density of the first conductive branch 101 is smaller than that of the second conductive branch 102 in the antenna module of the present disclosure, so that the antenna radiation energy of the embodiment of the present disclosure is mainly concentrated at the second conductive branch 102. Therefore, the antenna module of the present disclosure can reduce interference of the antenna module from the head and the hand when the first conductive branch 101 is blocked, relative to the existing antenna module.

In some embodiments, as shown in fig. 1, the antenna module includes:

a first impedance component 104 connecting the first conductive branch 101 and ground;

the second conductive branch 102 is connected to a first position a of the first conductive branch 101, and the first impedance component 104 is connected to a second position B of the first conductive branch 101;

the feeding point 103 is located between the first position a and the second position B.

That is, in the embodiment of the present disclosure, the first impedance component of the ground return is disposed on the first conductive branch where the feeding point is located, and the T antenna 1/4 mode that originally plays a dominant role in radiating energy of the first conductive branch can be configured to be an Inverted-F antenna (IFA) 1/4 mode that plays a dominant role in the second conductive branch through the first impedance component of the ground return.

Under the condition that the antenna module works in the IFA 1/4-like mode, the radiation current density of the second conductive branch is larger than that of the first conductive branch, so that the antenna radiation energy of the first conductive branch can be transferred to the second conductive branch, and the interference of the antenna module on the head and the hand can be reduced under the condition that the first conductive branch is shielded.

In the embodiment of the present disclosure, the first impedance component may be formed by at least one capacitive element, at least one resistive element, and/or at least one first inductive element in cascade, which is not limited by the embodiment of the present disclosure.

It should be noted that the first conductive branch may be a conductive strip, and the first position may be one end of the first conductive branch. The second location may be between the feed point and the other end of the first conductive branch. Preferably, the feeding point and the second position may both be located between the intermediate position and the first position of the first conductive branch.

In the embodiment of the disclosure, the feeding point is located between the first position and the second position, that is, the first impedance component to be grounded is disposed on the first conductive branch where the feeding point is located, and can be similar to the 1/4 mode of the IFA antenna, so that the mode of constructing the antenna module can be reconfigured by setting the feeding point between the first position and the second position, and the mode is constructed as the mode similar to IFA1/4 in which the second conductive branch plays a leading role.

Here, the operation mode of the antenna module of the present disclosure is not a large T mode any more, but an IFA-like mode. Illustratively, the radiation efficiency degradation of the existing antenna module and the antenna module of the present disclosure is actually measured in different modes, and the actually measured verification table is shown below.

Mode	B28	B5	B8
				Large T mode of existing antenna module	-4.6dB	-6.4dB	-6.9dB
IFA-like mode of antenna module of the present disclosure	-4dB	-5.2dB	-5.6dB

From the practical measurement verification table of different modes, it can be seen that the radiation efficiency of the antenna module of the present disclosure is better than the radiation efficiency of the existing antenna module at the three frequency bands of B28, B5 and B8. Wherein, B5 can correspond to the 824MHz to 894MHz frequency band; b8 can correspond to the 880MHz to 960MHz frequency band; b28 may correspond to the 703MHz to 803MHz band.

In some embodiments, as shown in fig. 1, the distance between the second location B and the feeding point 103 is in the range of 5 mm to 8 mm.

In the embodiment of the disclosure, the distance between the second position and the feeding point is set in the range of 5 mm to 8 mm, so that the antenna module can be better realized to construct the IFA 1/4-like mode, the sensitivity of the first conductive branch of the antenna module to be shielded is reduced, and the radiation efficiency of the antenna module can be improved.

In the embodiment of the disclosure, the inductance value of the first inductance element may be set according to the length of the second conductive branch. Here, in the case where the second conductive branch is longer, the inductance value of the first inductance element can be correspondingly reduced. Illustratively, in the case where the length of the second conductive branch is 35 millimeters, the inductance value of the corresponding first inductance element may be set to 8 nanohenries; in the case where the length of the second conductive branch is 45 mm, the inductance value corresponding to the first inductance element may be set to 4 nanohenries.

In the embodiment of the disclosure, the inductance value of the first inductance element is set to be in the range of 4-8 nanohenry, so that the excitation antenna module can be better constructed into the IFA 1/4-like mode, the sensitivity of the first conductive branch of the antenna module to shielding can be reduced, and the radiation efficiency of the antenna module can be improved. And, for setting up a plurality of components and parts cascade formation first impedance component, the first impedance component of this disclosed embodiment includes first inductance element, promptly returns ground through first inductance element, can reduce the occupation space of antenna module.

In the embodiment of the disclosure, the antenna module can receive and transmit wireless signals in different frequency bands by controlling the switch state of the tuning switch. Here, the tuning switch can be controlled to be in an off state, so that the antenna module receives and transmits wireless signals of the B5 frequency band; the tuning switch can be controlled to be in a closed state, so that the antenna module can receive and transmit wireless signals of the B8 frequency band and the B20 frequency band.

Illustratively, the tuning switch may be constituted by a mechanical switch or a switch chip, to which the disclosed embodiments are not limited.

In the embodiment of the disclosure, the impedance of the antenna module can be tuned by setting the tuning switch and the second impedance component so as to improve the receiving-transmitting conversion efficiency of the antenna.

In the embodiment of the disclosure, the inductance value of the second inductance element is set to be greater than or equal to 51 nanohenries, so that the inductance value can be equivalent to open circuit when the antenna module receives and transmits wireless signals, and better receiving and transmitting of wireless signals by the antenna module can be realized. And, for setting up a plurality of components and parts cascade formation second impedance subassembly, the second impedance subassembly of this disclosed embodiment includes the second inductance element, promptly through the tuning of second inductance element, can reduce the occupation space of antenna module.
