The implementations described in the following exemplary examples do not represent all implementations consistent with the invention. Rather, they are merely examples of apparatus and methods consistent with aspects of the invention as detailed in the accompanying claims.
Fig. 1 is a schematic diagram of an antenna module according to an exemplary embodiment. As shown in fig. 1, the antenna module includes:
A radiator;
A feeding point 101 located on the radiator;
a grounding point 102, which is located at a different position on the radiator from the feeding point 101;
wherein the radiator comprises: a first radiation path 103 having the feeding point 101 and the ground point 102 and a second radiation path 104 having the feeding point 101 and the ground point 102, the first radiation path 103 being different from the second radiation path 104;
The frequency band radiated by the first radiation path 103 is at least one same as the frequency band radiated by the second radiation path 104.
The antenna module is applied to terminal equipment and can be applied to wireless communication scenes such as Bluetooth (BT), wireless fidelity (WIRELESS FIDELITY, wiFi), a universal mobile communication system (Universal Mobile Telecommunications System, UMTS), long-term evolution (Long Term Evolution, LTE) and the like. The terminal device may be a wearable electronic device or a mobile terminal. The mobile terminal comprises a mobile phone, a notebook or a tablet computer; the wearable electronic device includes a smart watch or a smart bracelet, and embodiments of the present disclosure are not limited.
The radiator may be formed of an electrically conductive material. The embodiment of the disclosure can print the conductive material to form the radiator on the inner side of the shell of the terminal equipment, can attach the conductive material to the substrate of the flexible circuit board to form the radiator, and can multiplex the conductive shell of the terminal equipment into the radiator, and is not limited.
Wherein the conductive material includes, but is not limited to, a metal, an alloy, or a conductive plastic.
The radiator can be connected with the radio frequency front end module and is used for receiving a first electric signal generated by the radio frequency front end module and radiating a wireless signal under the excitation of the first electric signal; the radiator can also be used for converting the received wireless signal into a second electric signal and transmitting the second electric signal to the radio frequency front-end module to realize the receiving of the wireless signal.
Wherein, radio frequency front end module includes: a first amplifier, an antenna switch, a filter, a diplexer and a second amplifier. The first amplifier is used for amplifying the electric signal in the signal output channel. The antenna switch is used for realizing the switching between the receiving of the electric signal and the transmitting of the 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 diplexer is used for isolating the transmitted electrical signals and the received electrical signals, so that the antenna can work normally when receiving and transmitting wireless signals simultaneously. The second amplifier is used for amplifying the electric signal of the signal receiving channel. Therefore, the radio frequency front end module can be used for receiving and transmitting the electric signals, so that the radiator can be used for receiving and transmitting the wireless signals better.
The feeding point is used for transmitting an electric signal. The feed point can transmit the received first electric signal to the radiator, so that the radiator radiates a wireless signal under the excitation of the first electric signal; the antenna module can also receive a second electric signal obtained by converting the wireless signal by the radiator, and transmit the second electric signal to the radio frequency front end component of the antenna module to finish the receiving of the wireless signal in the antenna module.
The grounding point and the feeding point are respectively located at different positions of the radiator, and the method comprises the following steps: the ground point is spaced apart from the feed point between the two ends of the radiator. For example, the ground point is disposed at 3/4 of the radiator, and the feeding point is disposed at 1/2 of the radiator; as another example, the ground point is disposed at 2/5 of the radiator and the feed point is disposed at 3/5 of the radiator, and embodiments of the present disclosure are not limited.
In the embodiment of the disclosure, the grounding point can be connected to a grounding layer of a printed circuit board in the terminal equipment to realize an electric loop.
The radiator includes: a first radiation path having the feed point and the ground point and a second radiation path having the feed point and the ground point. That is, the first radiation path and the second radiation path share the same feeding point and ground point. Therefore, the space occupied by the antenna module in the terminal equipment can be reduced by sharing the same feed point and the same grounding point, and the space utilization rate of the terminal equipment is improved.
In an embodiment of the present disclosure, the first radiation path is different from the second radiation path. The first radiation path may include: a radiating portion and a first radiating portion between the feeding point and the ground point; the second radiation path may include: a radiating portion between the feeding point and the ground point and a second radiating portion. Wherein the first radiating portion and the second radiating portion are different radiating portions.
It should be noted that the first radiating portion and the second radiating portion may not coincide at all, for example, the first radiating portion may be a portion between the feeding point and the first end of the radiator, and the second radiating portion may be a portion between the ground point and the second end of the radiator, wherein the first end and the second end are located at different ends of the radiator.
The first radiating portion and the second radiating portion may also partially coincide. For example, the first radiating portion and the second radiating portion are located on the same side of the radiator, and the radiating length of the first radiating portion is greater than the radiating length of the second radiating portion.
In the embodiment of the disclosure, the first radiation path and the second radiation path may be used to transmit and receive wireless signals in a frequency range from 300MHz to 6GHz, and the embodiment of the disclosure is not limited.
The frequency band radiated by the first radiation path is at least one same as the frequency band radiated by the second radiation path. That is, the first radiation path and the second radiation path have the same radiation frequency band, and the same radiation frequency band may be one frequency band and multiple frequency bands, where the multiple frequency bands may include a frequency band corresponding to B1, a frequency band corresponding to B3, or a frequency band corresponding to B39, which is not limited in the embodiments of the disclosure.
Illustratively, as shown in fig. 2, the existing IFA antenna has a feeding point 202 and a ground point 201, and the IFA antenna transmits and receives wireless signals through one radiating arm. Under the condition that the antenna environment is bad or the antenna signal is weak in the antenna environment, the performance of the IFA antenna is rapidly reduced, the communication requirement cannot be met, and the user experience is poor.
Based on this, the embodiment of the present disclosure proposes that the radiator of the antenna module includes: a first radiation path having the feed point and the ground point and a second radiation path having the feed point and the ground point, the first radiation path being different from the second radiation path; the frequency band radiated by the first radiation path is at least one same as the frequency band radiated by the second radiation path. That is, in the embodiment of the disclosure, the first radiation path and the second radiation path can radiate the same frequency band, and when receiving and transmitting wireless signals, the receiving and transmitting efficiency can be overlapped in the same frequency band, so that the antenna performance of the antenna module can be improved. And the first radiation path and the second radiation path share the same feeding point and grounding point, so that the space occupied by the antenna module in the terminal equipment can be reduced by sharing the same feeding point and grounding point, and the space utilization rate of the terminal equipment is improved.

Wherein a portion between the feeding point 101, the ground point 102, and the first break 105 forms the first radiation path 103;
The portion between the feeding point 101, the ground point 102, and the second break 106 forms the second radiation path 104.
The radiator has a first break and a second break on different sides. When the radiator is in a strip shape, the first fracture and the second fracture can be respectively arranged at two opposite ends of the radiator; when the radiator is L-shaped, U-shaped or V-shaped, the first and second breaks may be provided at both ends of the radiator.
In the embodiment of the disclosure, the first break and the second break may be formed by providing a break point on the radiator. The shape and the size of the first fracture and the second fracture can be set according to actual needs. For example, the first and second breaks may be provided in the shape of an elongated strip or a circle. For another example, the length of the first break and the length of the second break may be between 10 millimeters and 70 millimeters, and the width of the first break and the width of the second break may be between 1 millimeter and 10 millimeters.

The portion between the feeding point, the ground point and the second break forms a second radiation path. That is, the second radiation path includes: a portion between the ground point and the feeding point and a portion between the feeding point and the second break.

In some embodiments, a distance between the feed point in the first radiation path and the first break is equal to a distance between the ground point in the second radiation path and the second break.
In the embodiment of the disclosure, the radiation distance of the antenna is inversely related to the frequency of the wireless signal transmitted and received by the antenna module. The longer the radiation distance of the antenna is, the smaller the frequency of the wireless signal transmitted and received by the antenna module is. The distance between the feeding point in the first radiation path and the first break is equal to the distance between the grounding point in the second radiation path and the second break, which can indicate that the first radiation path can radiate the same A frequency band as the second radiation path. Therefore, the receiving and transmitting efficiency of the antenna module can be overlapped in the A frequency band, and the antenna performance of the antenna module can be improved.
Illustratively, the a frequency band may be one sub-band of the 2G, 3G, 4G or sub6G frequency bands, which is not limited by the embodiments of the present disclosure.
In some embodiments, a distance between the ground point in the first radiation path and the first break is equal to a distance between the feed point in the second radiation path and the second break.

The longer the radiation distance of the antenna is, the smaller the frequency of the wireless signal transmitted and received by the antenna module is. The distance between the grounding point in the first radiation path and the first break is equal to the distance between the feeding point in the second radiation path and the second break, which can indicate that the first radiation path can radiate the same B frequency band as the second radiation path. Therefore, the receiving and transmitting efficiency of the antenna module can be overlapped in the B frequency band, and the antenna performance of the antenna module can be improved.
Illustratively, the a frequency band and the B frequency band are different frequency bands, and the B frequency band may be one sub-frequency band of 2G, 3G, 4G, or sub-6G frequency bands, which is not limited in the embodiments of the present disclosure.

To facilitate an understanding of the above disclosed embodiments, the present application is exemplified as follows:
The first radiation path in the antenna module can excite two quarter-wavelength modes, namely a mode from the feed point to the quarter-wavelength mode of the first fracture and a mode from the ground point to the quarter-wavelength mode of the first fracture.
The second radiation path in the antenna module may also excite two quarter-wavelength modes, namely a mode from the feed point to the quarter-wavelength mode of the second break and a mode from the ground point to the quarter-wavelength mode of the second break.
The distance between the feed point in the first radiation path and the first break is equal to the distance between the grounding point in the second radiation path and the second break, so that the first radiation path and the second radiation path can both transmit and receive wireless signals of the A frequency band;
The distance between the grounding point in the first radiation path and the first break is equal to the distance between the feeding point in the second radiation path and the second break, so that the first radiation path and the second radiation path can both transmit and receive wireless signals of the B frequency band.
Therefore, the frequency bands of the first radiation path for receiving and transmitting the wireless signals and the frequency bands of the second radiation path for receiving and transmitting the wireless signals in the antenna module are the same, namely the A frequency band and the B frequency band, so that the receiving and transmitting efficiency of the antenna module can be overlapped in the A frequency band and the B frequency band, and the receiving and transmitting performance of the antenna module can be improved.
As shown in FIG. 5 and FIG. 6, the antenna module has two current paths distributed on 0.86G and 0.96G, which can excite two quarter-wavelength modes respectively. As shown in fig. 7, the transceiving efficiency of the stacked antenna module may be improved by 2dB compared to the transceiving efficiency of the antenna module before stacking.
