The application relates to the technical field of antenna design, in particular to a carrier aggregation antenna structure and a mobile terminal.
Background
With the development of communication technology, the demand of users for Carrier Aggregation (CA) is increasing. The CA technology can aggregate 2-5 carriers together, realize the maximum transmission bandwidth of 100MHz, has raised the transmission rate of the up-and-down link effectively.
With the wide application of the CA technology in the mobile phone, the number of the antennas of the mobile phone is increasing, and the number of the antennas supporting the communication mode and the frequency band are wider and wider, which is a challenge to the antenna design of the mobile phone. The antenna design is an indispensable link in the successful chain of mobile phone design, and the performance of the antenna directly causes many problems.
Since the CA technology means that 2 or more carriers are simultaneously transmitted, when the 2 or more carriers belong to different frequency bands, a certain influence may be exerted on the antenna performance. For example, carriers belonging to a low-frequency band and a medium/high-frequency band are realized by using the same antenna, and due to the low frequency, a tuning matching circuit is needed to realize the performance of antennas in different low-frequency bands, and the low-frequency tuning matching circuit affects the medium-frequency performance, thereby causing the performance of the medium-frequency antenna to shift and decrease.
At present, in some models with poor antenna environment or in order to meet the performance of carrier aggregation antennas, antennas are sometimes designed in a split mode. For example, all frequency bands originally implemented by the same antenna are split into two antennas. However, due to the high integration level of the mobile phone, it is difficult to find an ideal environment and position after the antenna is detached to realize the performance of the additional antenna, which also causes the performance of the antenna to be degraded.

The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
Referring to fig. 1, a schematic architecture of an embodiment of a carrier aggregation antenna structure of the present application is shown. As shown in fig. 1, the carrier aggregation antenna structure includes: a first main set antenna 11, a second main set antenna 12 and a one-to-one diversity antenna 13.
The first main set antenna 11 is used for performing main set transmission/reception of first frequency band signals and performing main set transmission of second frequency band signals; wherein the first dominant set antenna 11 has a first priority in antenna environment selection. The second main set antenna 12 is used for main set reception of the second frequency band signals; wherein the second dominant set of antennas has a second priority in antenna environment selection. The diversity antenna 13 is configured to perform diversity reception of the first frequency band signal and perform diversity reception of the second frequency band signal; wherein the diversity antenna has a third priority in antenna environment selection. And wherein the first priority has a higher priority level than the second priority and the third priority.
In the conventional project design of mobile terminals such as mobile phones, the transmission of the main set (including the low-frequency main set and the medium/high-frequency main set) generally has only one path, and generally, each manufacturer and operator have higher requirements on the transmission of the main set, so that antennas for realizing the transmission of the main set are generally placed at positions with better antenna environments, such as the bottom position of the mobile terminal. I.e. the first dominant set of antennas 11 has the highest priority level in antenna environment selection.
The diversity antenna 13 for diversity reception and the second main set antenna 12 split to be used solely for main set reception require a smaller antenna bandwidth to be implemented and therefore have lower requirements on the antenna environment. Thus, the second priority and the third priority may be of the same priority level and both be less than the first priority.
In a further embodiment, the frequency interval of the first frequency band signal covers low frequency, and the frequency interval of the second frequency band signal covers medium/high frequency. Wherein, the low frequency can include a band5/band12 frequency band, and the frequency range is 600Mhz-900Mhz; the intermediate frequency can comprise a band2/band4/band66 frequency band, and the frequency range is 1710Mhz-2200Mhz; the high frequencies may include band7/band30 frequency bands, with frequencies ranging from 2300Mhz to 2700Mhz.
In a further embodiment, the carrier aggregation antenna structure further comprises a tuning matching circuit 14. The tuning matching circuit 14 is connected to the first main set antenna 11. Preferably, the tuning matching circuit 14 is a low frequency main set transceiver tuner (tuner). Due to the low frequency, the bandwidth of the low frequency antenna which can be realized is relatively narrow, so that tuning matching circuits are needed to realize the performance of antennas in different low frequency bands, namely, different antenna tuning devices are used during communication in different low frequency bands. For a specific implementation of the low frequency main set transceiver tuner, reference may be made to the prior art, and details thereof are not described herein.
Currently, the CAs required by an operator mostly refer to downlink CAs, that is, there are 2 carriers during reception; in terms of transmission, there are again only 1 carrier. In view of this, the independent splitting of the medium/high frequency major set reception by the independent major set antenna ensures that the low frequency antenna tuning does not affect the medium/high frequency reception; since the low frequency tuning is acceptable for the effect of mid/high frequency transmission, the mid/high frequency main set transmission can still be implemented with the same antenna as the low frequency main set, and the low frequency antenna tuning will not cause the performance of the mid frequency band antenna to shift and degrade.
In the prior art, the low-frequency main set transceiving and the medium/high-frequency main set transceiving are realized by using the same antenna, and the low-frequency antenna tuning can cause the performance of the medium-frequency band antenna to shift and reduce. For example, when CA 12A +4A, tuning match a is used, and when tuning match a is used, both B12 and B4 are the optimal performance; while CA 5A +4A, tuning match B is used, B5 is the optimal performance, but B4 performance is shifted and reduced; this is undesirable for the operator. The method and the device realize the receiving of the medium/high frequency main set by independently detaching the medium/high frequency main set through the independent main set antenna, the transmitting of the medium/high frequency main set can still be realized by the same antenna with the low frequency main set, and the problems of antenna performance deviation and reduction of the medium frequency band antenna performance caused by the tuning of the low frequency antenna are avoided. Compared with the method that the medium/high frequency main set is simultaneously transmitted/received, the method and the device have the advantages that the medium/high frequency main set is independently received by one antenna, the required antenna bandwidth is smaller, the requirement on the antenna environment is lower, and the proper position can be found on the mobile terminal more easily.
In a further embodiment, the carrier aggregation antenna structure further comprises a Transceiver (Transceiver) 19. The transceiver 19 is connected to the first main set antenna 11, the second main set antenna 12 and the diversity antenna 13, respectively. Further, the transceiver 19 is connected to the first main set antenna 11 through the tuning matching circuit 14. The transceiver 19 is used for transmitting signals to each antenna and receiving received signals fed back by each antenna respectively. The specific implementation of the transceiver 19 can refer to the prior art, and is not described herein.
The present application divides the antenna into three: a first main set antenna for low frequency main set transmission/reception + mid/high frequency main set reception, a second main set antenna for mid/high frequency main set reception, and a diversity antenna for low frequency diversity reception + mid/high frequency diversity reception. A first main set antenna for low frequency main set transmission/reception + mid/high frequency main set reception with an antenna tuning device (i.e., a low frequency main set transceiver tuner); the frequency band which needs to be realized is the widest and most important, and the priority is the highest, so that the antenna can be placed at the position with the best environment of the mobile terminal, such as the bottom position of the mobile terminal. Diversity antenna for low frequency diversity reception + medium/high frequency diversity reception without antenna tuning device; second, the priority may be placed, for example, on the top or on a side of the mobile terminal. A second main set antenna for medium/high frequency main set reception, also without an antenna tuning device; the priority can be the same as that of the diversity antenna, and a proper position can be searched and placed on the mobile terminal; for example, the first main set antenna may be disposed at the bottom of the mobile terminal at an interval, the diversity antenna may be disposed at the top or a side of the mobile terminal at an interval, or both the first main set antenna and the diversity antenna may be disposed at different positions.
The carrier aggregation antenna structure is realized by independently detaching the receiving of the medium/high frequency main set through the independent main set antenna, the transmitting of the medium/high frequency main set is still realized by the same antenna with the low frequency main set, and the problem that the performance of the medium frequency band antenna deviates and drops due to the fact that the antenna in the CA state is tuned by the low frequency antenna is avoided. The method and the device have the advantages that the medium/high frequency main set receiving is realized by independently detaching one antenna, the bandwidth of the antenna to be realized is smaller, the requirement on the antenna environment is lower, and the proper position on the mobile terminal can be found and placed more easily; and then the antenna of the important frequency band is guaranteed to utilize the best position of the mobile terminal to the maximum extent, and the optimal antenna efficiency is realized.
