图 1为相关技术中用于 SVLTE架构的天线电路组成结构示意图， 如图 1所示， 用于 SVLTE架构的天线电路 100包括： 第一射频开关 11、 第二射 频开关 12、 第三射频开关 13、 第一天线 14、 第二天线 15、 第三天线 16; 其中， 第一射频开关 11包括公共端 110、 第一开关 111、 第二开关 112、 第 三开关 113。 1 is a schematic structural diagram of an antenna circuit for an SVLTE architecture in the related art. As shown in FIG. 1, an antenna circuit 100 for an SVLTE architecture includes: a first RF switch 11 and a second shot. The frequency switch 12, the third RF switch 13, the first antenna 14, the second antenna 15, and the third antenna 16; wherein the first RF switch 11 includes a common terminal 110, a first switch 111, a second switch 112, and a third switch 113.
其中， 第一天线 14连接到所述第一射频开关 11的公共端 110， 所述第 一射频开关 11的第一开关 111连接到 GSM收发支路上， 所述第一射频开 关 11的第二开关 112连接到 WCDMA收发支路上， 所述第一射频开关 11 的第三开关 113连接到 LTE收发支路上；  The first antenna 14 is connected to the common end 110 of the first RF switch 11, the first switch 111 of the first RF switch 11 is connected to the GSM transceiver branch, and the second switch of the first RF switch 11 is connected. 112 is connected to the WCDMA transceiver branch, and the third switch 113 of the first RF switch 11 is connected to the LTE transceiver branch;
第二天线 15连接到第二射频开关 12的一端， 第二射频开关 12的另一 端连接到 CDMA IX收发支路上； 第三天线 16连接到第三射频开关 13的 一端， 第三射频开关 13的另一端连接到 LTE分集接收支路上。  The second antenna 15 is connected to one end of the second RF switch 12, the other end of the second RF switch 12 is connected to the CDMA IX transceiver branch; the third antenna 16 is connected to one end of the third RF switch 13, and the third RF switch 13 is The other end is connected to the LTE diversity reception branch.
对于图 1所示的天线电路， 由于 GSM/ WCDMA/LTE收发支路上既传 输高频信号也传输低频信号， 所以， 第一天线 14为低频天线， 需要的空间 大； CDMA IX收发支路上只传输低频信号， 所以， 第二天线 15也为低频 天线， 需要的空间也大； 而 LTE分集接收支路上只传递高频信号， 所以， 第三天线 16为高频天线，需要的空间小。可以看出，图 1中所示用于 SVLTE 架构的天线电路 100 的三才艮天线中， 有两才 氏频天线和一 ^:艮高频天线， 相 应的， 用于 SVLTE架构的天线电路 100中较多的低频天线， 就会导致天线 所需要的空间大， 这样， 增大了天线设计的难度。 For the antenna circuit shown in FIG. 1, since the GSM/WCDMA/LTE transmission and reception branch transmits both the high frequency signal and the low frequency signal, the first antenna 14 is a low frequency antenna and requires a large space; the CDMA IX transceiver branch transmits only The low frequency signal, therefore, the second antenna 15 is also a low frequency antenna, and the required space is also large; and the LTE diversity receiving branch transmits only high frequency signals, so the third antenna 16 is a high frequency antenna, and the required space is small. It can be seen in FIG. 1 ternary Gen antenna for an antenna circuit 100 shown in SVLTE architecture, there are only two-frequency antenna and a ^ s: Gen high frequency antenna 100, a respective antenna circuit architecture for SVLTE More low-frequency antennas will result in a larger space required by the antenna, which increases the difficulty of antenna design.
举个例子来说， 如果运营商的 LTE频段是 Bl、 B3， 都是高频； CDMA IX频段是 BC0， 是低频； 漫游 GSM四频和 WCDMA四频， 高低频都有； 在实际应用时， LTE频段 Bl、 B3和漫游 GSM四频和 WCDMA四频使用 第一天线 14， CDMA IX频段 BC0使用第二天线 15， LTE分集接收使用第 三天线 16; 相应的， 第一天线 14为 ^频天线， 第二天线 15为 ^频天线， 第三天线 16为高频天线； 显然会需要较大空间， 增加天线设计难度。  For example, if the LTE frequency band of the operator is Bl and B3, both are high frequency; the CDMA IX frequency band is BC0, which is low frequency; the roaming GSM quad frequency and WCDMA quad frequency, both high and low frequency; In practical applications, the LTE frequency band Bl, B3 and roaming GSM quad-band and WCDMA quad-band use the first antenna 14, CDMA IX band BC0 uses the second antenna 15, LTE diversity receives the use of the third antenna 16; correspondingly, the first antenna 14 is the frequency antenna, the second antenna 15 is a frequency antenna, and the third antenna 16 is a high frequency antenna; obviously, a larger space is required, and the antenna design difficulty is increased.
发明人在实施本发明的过程中发现， 通过调整射频开关的连接关系， 使所有包括低频频段的收发支路通过射频开关集中使用一根天线， 以减少 低频天线的数量， 增加高频天线的数量， 进而使天线设计中所需要的空间 变小， 且能降低天线设计的难度。 In the process of implementing the present invention, the inventors have found that by adjusting the connection relationship of the radio frequency switch, Make all the transmitting and receiving branches including the low frequency band use one antenna through the RF switch to reduce the number of low frequency antennas, increase the number of high frequency antennas, and thus reduce the space required in the antenna design, and reduce the antenna design. Difficulty.
其中， 本发明实施例中， 对于 WCDMA/GSM/LTE 收发通过射频开关 共用一根天线的技术方案， 先将 LTE收发的相关频段剥离出来， 保留 GSM 和 WCDMA相关收发频段； 然后将 CDMA IX的相关收发频段和保留的 GSM/WCDMA相关收发频段均连接到同一个射频开关上， 共用一根天线； 并将剥离出来的 LTE相关收发频段使用一根天线， WCDMA/LTE分集接收 使用一根天线； 如此， WCDMA/GSM/CDMA 1X收发连接并使用低频天线， 而 WCDMA/LTE分集接收连接并使用高频天线， LTE收发连接并使用高频 天线。  In the embodiment of the present invention, for the technical solution that the WCDMA/GSM/LTE transceivers share an antenna through the RF switch, the relevant frequency bands of the LTE transceiver are first stripped out, and the GSM and WCDMA related transceiver bands are reserved; then the CDMA IX is related. The receiving and transmitting frequency bands and the reserved GSM/WCDMA related receiving and transmitting frequency bands are all connected to the same RF switch and share one antenna; and the stripped LTE related receiving and transmitting frequency band uses one antenna, and WCDMA/LTE diversity receives and uses one antenna; WCDMA/GSM/CDMA 1X transceivers use low frequency antennas, while WCDMA/LTE diversity receive connections and use high frequency antennas, LTE transceiver connections and use high frequency antennas.

The required space is large; only the high frequency signal is transmitted on the LTE transmitting and receiving branch, so the second antenna 22 is a high frequency antenna, and the required space is small; and the LTE diversity receiving branch also transmits only the high frequency signal, so the third antenna 16 For the high frequency antenna, the required space is small; it can be seen that there are two high frequency antennas and one low frequency antenna among the three antennas of the antenna circuit 200 for the SVLTE architecture shown in FIG. 2, compared with FIG. The high frequency antenna in the antenna circuit 200 of the SVLTE architecture can save space required by the antenna and can reduce the difficulty of the antenna design.

图 3 为本发明实施例的天线电路的实现方法流程示意图， 可以用于 SVLTE架构， 如图 3所示， 所述实现方法包括以下步骤：  FIG. 3 is a schematic flowchart of a method for implementing an antenna circuit according to an embodiment of the present invention, which may be used in an SVLTE architecture. As shown in FIG. 3, the implementation method includes the following steps:
步骤 301 : 将 CDMA IX收发支路通过第一射频开关与 GSM收发支路 和 WCDMA收发支路共同连接到第一天线上；  Step 301: Connect the CDMA IX transceiver branch to the first antenna through the first RF switch and the GSM transceiver branch and the WCDMA transceiver branch;
