In this embodiment, a multimode antenna applied to the mobile terminal is provided, and fig. 2 is a schematic structural diagram of a multimode antenna according to an embodiment of the present invention, as shown in fig. 2, the multimode antenna includes: an antenna, a printed circuit board and an antenna support (i.e. a dielectric substrate). And the antenna bracket is electrically connected with the printed circuit board. The antenna is arranged on the antenna bracket. In an alternative embodiment, the antenna is laser etched on the antenna support. The antenna is provided with a plurality of feeding points, and the working frequency bands of the antenna array corresponding to each feeding point in the plurality of feeding points are different.
Alternatively, as shown in fig. 2, the antenna is an inverted F antenna (i.e., IFA) and the first end of the antenna is electrically connected to the printed circuit board.
Alternatively, as shown in fig. 2, the plurality of feeding points include: a first feeding point a, a second feeding point B and a third feeding point C. The distance between the first feeding point and the second end of the antenna is a first distance, the distance between the second feeding point and the second end is a second distance, and the distance between the third feeding point and the second end is a third distance. The first distance is greater than the second distance and the second distance is greater than the third distance. In addition, the fourth distance in fig. 2 is the distance between the first feeding point a and the antenna ground point. That is, the electrical connection of the antenna bracket to the printed circuit board corresponds to the grounding of the first end of the antenna.
Optionally, the bandwidth covered by the operating frequency band of the antenna element corresponding to the first feeding point is 2.496-2.69 GHz. The bandwidth covered by the working frequency band of the antenna array corresponding to the second feeding point is 3.3-3.8 GHz. The bandwidth covered by the working frequency band of the antenna array corresponding to the third feeding point is 4.4-5.0 GHz.
Specifically, the working frequency band of the antenna array corresponding to the first feeding point A is n41, the covered bandwidth is 2.496-2.69GHz, and the return loss S11< -10 dB. The working frequency band of the antenna array corresponding to the second feeding point B is n78, the covered bandwidth is 3.3-3.8GHz, and the return loss S11< -10 dB. The working frequency band of the antenna array corresponding to the third feeding point C is n79, the covered bandwidth is 4.4-5.0GHz, and the return loss S11< -10 dB. Therefore, the intelligent switching of the antenna frequency band can be realized by dynamically changing the position of the antenna feeding point on the antenna array.
It should be noted that, considering that the multi-mode antenna is mainly applied to the fifth generation mobile communication technology (5G) mobile terminal, the above-mentioned multiple feeding points including the first feeding point a, the second feeding point B and the third feeding point C are only one optional example of the present invention, and do not constitute a limitation to the present invention. The plurality of feeding points may further include bandwidths covered by operating bands of other antenna elements. For example: the plurality of feeding points may further include an antenna element corresponding to a fourth feeding point D (not shown in the figure), and the operating frequency band of the antenna element is n77, and the covered bandwidth is 3.3-4.2 GHz.
In this embodiment, a communication method of a multimode antenna operating in the mobile terminal is provided, and fig. 3 is a flowchart of a communication method of a multimode antenna according to an embodiment of the present invention, as shown in fig. 3, the multimode antenna includes: the antenna comprises an antenna, a printed circuit board and an antenna bracket, wherein the antenna is arranged on the antenna bracket, and the method comprises the following steps:
step S32, receiving a radio frequency signal from a base station through an antenna, wherein the antenna is provided with a plurality of feeding points, and the working frequency bands of antenna elements corresponding to each feeding point in the plurality of feeding points are different;
step S34, determining a feeding point to be used from a plurality of feeding points based on the transmission frequency of the radio frequency signal;
and step S36, performing communication interaction with the base station by using the feeder point to be used.
In the related art, if different types of radio frequency signals need to be received and processed through multiple feeding points on a mobile terminal, multiple antennas need to be configured for each feeding point, and intercommunication cannot be achieved among the multiple feeding points, so that excessive terminal space is occupied, terminal clear space is small, and dynamic switching cannot be performed among the multiple feeding points. Through the steps, the mode that the antenna receives the radio frequency signal from the base station, the antenna is provided with a plurality of feeding points, and the working frequency range of the antenna array corresponding to each feeding point in the plurality of feeding points is different, the feeding point to be used is determined from a plurality of feeding points through the transmitting frequency of the radio frequency signal, and the feeding point to be used is utilized to carry out communication interaction with the base station, so that the purpose that the array of the terminal antenna corresponding to different feeding ends works in different frequency bands is achieved, thereby realizing the technical effects of effectively improving the terminal clear space and intelligently switching among a plurality of feed points (namely a plurality of antenna frequency bands), and further, the technical problems that the terminal clear space is small and dynamic switching among a plurality of feeding points cannot be performed due to the fact that the communication antenna design mode provided in the related technology occupies too much terminal space are solved.
In an alternative embodiment, the plurality of feeding points include: a first feeding point a, a second feeding point B and a third feeding point C. The distance between the first feeding point and the second end of the antenna is a first distance, the distance between the second feeding point and the second end is a second distance, and the distance between the third feeding point and the second end is a third distance. The first distance is greater than the second distance and the second distance is greater than the third distance.
According to the antenna principle, the longer the radiator of the antenna, the lower the radiation frequency. When a radio frequency signal enters the antenna end from the first feeding point A, the working frequency band of the antenna array corresponding to the first feeding point A is n41, the covered bandwidth is 2.496-2.69GHz, and the return loss S11< -10 dB. When a radio-frequency signal enters the antenna end from the second feeding point B, the working frequency band of the antenna array corresponding to the second feeding point B is n78, the covered bandwidth is 3.3-3.8GHz, and the return loss S11< -10 dB. When a radio-frequency signal enters the antenna end from the third feeding point C, the working frequency band of the antenna array corresponding to the third feeding point C is n79, the covered bandwidth is 4.4-5.0GHz, and the return loss S11< -10 dB. Therefore, the intelligent switching of the antenna frequency band can be realized by dynamically changing the position of the antenna feeding point on the antenna array.
The operating frequency band n41 is a shared frequency band of 5G radio frequency signals and fourth generation mobile communication technology (4G) radio frequency signals. The working frequency band n78 and the working frequency band n79 are the exclusive frequency bands of 5G radio frequency signals.
Alternatively, the step of determining a feeding point to be used from a plurality of feeding points based on the transmission frequency S34 may include performing the steps of:
step S341, obtaining a frequency band suitable for the transmitting frequency;
step S342, selecting a working frequency band adapted to the frequency band suitable for the transmitting frequency according to the working frequency band of the antenna array corresponding to each feeding point in the plurality of feeding points;
and S343, determining a feeding point to be used according to the selected working frequency band.
In a practical application scenario, a mobile terminal may receive a 5G radio frequency signal, a 4G radio frequency signal and a third generation mobile communication technology (3G) radio frequency signal sent by different base stations. The processing priorities of different types of radio frequency signals can be preset in the mobile terminal. For example: preferentially receiving and processing 5G radio frequency signals, secondly receiving and processing 4G radio frequency signals, and then receiving and processing 3G radio frequency signals, even second generation mobile communication technology (2G) radio frequency signals. In addition, different types of radio frequency signals can be selected in a targeted manner under different application scenes. For example: under the application scene of the Internet, the 5G radio frequency signals can be preferentially received and processed; and in a conversation application scene, the 3G radio frequency signal can be preferentially received and processed.
If the mobile terminal receives a radio-frequency signal from the base station through the antenna, the frequency band suitable for the transmitting frequency of the radio-frequency signal needs to be acquired firstly, then the working frequency band adaptive to the frequency band suitable for the transmitting frequency is selected according to the working frequency band of the antenna array corresponding to each feeding point in the plurality of feeding points, and finally the feeding point to be used is determined according to the selected working frequency band.
For example: if the transmitting frequency of the radio frequency signal received by the mobile terminal through the antenna is 3.6GHz, the bandwidth 3.3-3.8GHz covered by the working frequency band n78 of the antenna array corresponding to the second feeding point B is the working frequency band adapted to the frequency band to which the transmitting frequency is applicable. Therefore, the second feeding point B can be selected from the first feeding point A, the second feeding point B and the third feeding point C as a feeding point to be used for communication interaction between the mobile terminal and the base station. However, if the transmission frequency of the radio frequency signal subsequently received by the mobile terminal through the antenna is 4.5GHz, the bandwidth 4.4-5.0GHz covered by the operating frequency band n79 of the antenna array corresponding to the third feeding point C is an operating frequency band adapted to the frequency band to which the transmission frequency is applied. Therefore, the third feeding point C can be selected from the first feeding point A, the second feeding point B and the third feeding point C as a feeding point to be used for communication interaction between the mobile terminal and the base station. Considering that the feeding point currently used by the mobile terminal is the second feeding point B, it is necessary to switch from the second feeding point B to the third feeding point C. Thereby enabling intelligent switching between multiple feed points (i.e. multiple antenna bands).
For another example: if the transmission frequency of the radio frequency signal received by the mobile terminal through the antenna is 2.6GHz, the bandwidth 2.496-2.69GHz covered by the working frequency band n41 of the antenna array corresponding to the first feeding point a is the working frequency band adapted to the frequency band to which the transmission frequency is applicable. Therefore, the first feeding point A can be selected from the first feeding point A, the second feeding point B and the third feeding point C as a feeding point to be used for communication interaction of the mobile terminal and the base station. However, if the transmission frequency of the radio frequency signal subsequently received by the mobile terminal through the antenna is 4.5GHz, the bandwidth 4.4-5.0GHz covered by the operating frequency band n79 of the antenna array corresponding to the third feeding point C is an operating frequency band adapted to the frequency band to which the transmission frequency is applied. Therefore, the third feeding point C can be selected from the first feeding point A, the second feeding point B and the third feeding point C as a feeding point to be used for communication interaction between the mobile terminal and the base station. Considering that the feeding point currently used by the mobile terminal is the first feeding point a, it is necessary to switch from the first feeding point a to the third feeding point C. Thereby enabling intelligent switching between multiple feed points (i.e. multiple antenna bands).
