Description

技术领域
本申请涉及移动通信技术领域，尤其涉及一种天线装置及终端设备。
 背景技术
由于毫米波频率高，信号传输衰减大，5G移动终端设备多采用阵列天线波束赋形提升信号强度，并且采用波束扫描技术扩大信号通信角度。波束赋形以及波束扫描原理是通过控制毫米波阵列天线模组中每一个发射和接受单元的相位和信号幅度，从而增强阵列天线辐射的强度和角度。
但是，目前市场上的部分5G毫米波移动通讯终端产品，天线阵列只采用数字移相器控制阵列天线中发射和接收单元的相位，没有控制输入单个单元信号的幅度，因此阵列天线工作在某些角度，尤其是边缘角度，会出现副瓣过大，影响信号接收和发射效率，并且有引入其他外界干扰信号的风险。

如图1所示，为本申请实施例一提供的天线装置的电路原理图，包括：一功分器80及多个天线单元。所述天线装置用于终端设备。本申请实施例一中所述的功分器80也叫作功率分配器（power divider），其是一种将一路输入信号能量分成两路或多路输出相等或不相等能量的器件，当然也可反过来将多路信号能量合成一路输出，此时可也称为合路器。
每一所述天线单元与所述功分器80电性连接，每一所述天线单元包括：一功率衰减器4及一辐射部1。
结合参阅图2，所述辐射部1位于第一介质基板10上。所述功率衰减器4位于第二介质基板30上。在所述第一介质基板10与所述第二介质基板30之间还设有一接地板20，所述接地板20上设有多个通孔2，所述通孔2的数量与天线单元的数量相同。
所述功率衰减器4与所述功分器80电性连接，所述功率衰减器4用于加载一算法对输入的信号功率做衰减。其中所述算法为道尔夫-切比雪夫算法与泰勒算法及其组合的其中一者。当天线装置中的天线单元超过4个时，一般最多将4个天线单元分为第一组天线阵列，多出的天线单元可分为第二组天线阵列，甚至更多的组天线阵列。相同组天线阵列中所有的所述功率衰减器4可以统一加载道尔夫-切比雪夫算法，或者可以统一加载泰勒算法，或者部分的功率衰减器4加载道尔夫-切比雪夫算法，其他部分的功率衰减器4加载泰勒算法。也就是说，在天线装置中道尔夫-切比雪夫算法与泰勒算法可以混用也可以在天线装置中仅加载其中一种算法。
需要说明的是，道尔夫-切比雪夫算法中电流分布可以将一部分副瓣的能量转移到主瓣上，从而降低副瓣电平水平，获得最窄的主瓣宽度或者在给定的主瓣宽度时，获得最低的副瓣电平。与道尔夫-切比雪夫算法保持相同的副瓣电平不同的是，泰勒分布可以使得在主瓣附近的几个副瓣电平相同，而其余的副瓣电平呈现依次递减的趋势。泰勒分布通过波瓣零点的位置来调节副瓣电平，已知离主瓣较远的副瓣电平都会依次降低。对于靠近主瓣的副瓣，将其波瓣零点的位置向主瓣方向移动，就可以使相应的副瓣电平降低。
所述多个天线单元呈一直线排布，但不限于此，在其他实施例中多个天线单元可以呈曲线排布。
每一所述天线单元输入的信号幅值相同，但每一所述天线单元输出的信号幅值不一定相同。具体是根据每一所述天线单元在天线阵列中所排布的位置决定该天线单元输出的幅值。例如天线阵列呈直线排布时，其中处于中间位置的天线单元输出幅值大于两边天线单元的输出幅值。
所述辐射部1用于将接收信号传送至所述功率衰减器4或从所述功率衰减器4接收发射信号。
所述天线装置还包括：一移相器3。
所述移相器3与所述功率衰减器4电性连接，所述移相器3用于改变信号主瓣的相位。
当天线装置发射一信号时，所述信号从所述终端设备内部对应的电路传送至所述功分器80，所述功分器80将信号分成多路（与所述多个天线单元的数量相同）等幅信号。每一所述多路等幅信号分别通过所述功率衰减器4，所述功率衰减器4加载道尔夫-切比雪夫算法或泰勒算法，对输入的等幅信号功率做相应的衰减。将衰减后的信号经过移相器3，调整信号的发射相位。最后从天线单元的辐射部1发射出去。其中所述辐射部1与所述移相器3不直接连接，所述信号通过接地板20上的通孔2耦合至辐射部1。
当天线装置从所述终端设备外部接收一信号时，所述信号由多个辐射部1输入多个天线单元。每一所述多个辐射部1将接收的信号通过通孔2耦合至移相器3上，通过移相器3调整信号的接收相位。将调整相位后的信号通过功率衰减器4，所述功率衰减4加载道尔夫-切比雪夫算法或泰勒算法，对接收的信号功率做相应的衰减。在将衰减后的多路信号发送至功分器80中，此时功分器80会将多路信号合并成一路信号。
本申请的优点在于，本申请通过在阵列天线的每一天线单元中增加一功率衰减器，所述功率衰减器用于加载道尔夫-切比雪夫算法和/或泰勒算法对输入的信号功率做衰减，能有效抑制阵列天线的副瓣增益，并且保持相同的主瓣增益和宽度。
如图3所示，为本申请实施例二提供的一种天线装置310的电路原理图，包括：一功分器80及多个天线单元。所述天线装置310用于终端设备。实施例二中所述的功分器80也叫作功率分配器（power divider），其是一种将一路输入信号能量分成两路或多路输出相等或不相等能量的器件，当然也可反过来将多路信号能量合成一路输出，此时可也称为合路器。
在实施例二中所述多个天线单元包括：一第一天线单元40、一第二天线单元50、一第三天线单元60及一第四天线单元70。所述第一天线单元40、所述第二天线单元50、所述第三天线单元60及所述第四天线单元70呈一直线排布。
四个天线单元40、50、60及70分别与所述功分器80电性连接，每一天线单元40、50、60及70包括：一功率衰减器4及一辐射部1。
结合参阅图2，所述辐射部1位于第一介质基板10上。所述功率衰减器4位于第二介质基板30上。在所述第一介质基板10与所述第二介质基板30之间还设有一接地板20，所述接地板20上设有四个通孔2，所述通孔2的数量与天线单元的数量相同。
所述功率衰减器4与所述功分器80电性连接，所述功率衰减器4用于加载一算法对输入的信号功率做衰减。其中所述算法为道尔夫-切比雪夫算法与泰勒算法及其组合的其中一者。在实施例二中将四个天线单元分为一组天线阵列，所述天线阵列中所述功率衰减器4加载道尔夫-切比雪夫算法或泰勒算法。因此，实施例二中的天线装置中道尔夫-切比雪夫算法与泰勒算法仅加载其中一种算法。
需要说明的是，道尔夫-切比雪夫算法中电流分布可以将一部分副瓣的能量转移到主瓣上，从而降低副瓣电平水平，获得最窄的主瓣宽度或者在给定的主瓣宽度时，获得最低的副瓣电平。与道尔夫-切比雪夫算法保持相同的副瓣电平不同的是，泰勒分布可以使得在主瓣附近的几个副瓣电平相同，而其余的副瓣电平呈现依次递减的趋势。泰勒分布通过波瓣零点的位置来调节副瓣电平，已知离主瓣较远的副瓣电平都会依次降低。对于靠近主瓣的副瓣，将其波瓣零点的位置向主瓣方向移动，就可以使相应的副瓣电平降低。
所述四个天线单元呈一直线排布，但不限于此，在其他实施例中四个天线单元可以呈曲线排布。
四个天线单元输入的信号幅值相同，但四个天线单元输出的信号幅值不一定相同。具体是根据四个天线单元在天线阵列中所排布的位置决定该天线单元输出的幅值。例如天线阵列呈直线排布时，其中处于中间位置的天线单元输出幅值大于两边天线单元的输出幅值。
所述辐射部1用于将接收信号传送至所述功率衰减器4或从所述功率衰减器4接收发射信号。
所述天线装置还包括：一移相器3。
所述移相器3与所述功率衰减器4电性连接，所述移相器3用于改变信号主瓣的相位。
当天线装置发射一信号时，所述信号从所述终端设备内部对应的电路传送至所述功分器80，所述功分器80将信号分成四路（与四个天线单元的数量相同）等幅信号。四路等幅信号分别通过所述功率衰减器4，所述功率衰减器4加载道尔夫-切比雪夫算法或泰勒算法，对输入的等幅信号功率做相应的衰减。将衰减后的信号经过移相器3，调整信号的发射相位。最后从天线单元的辐射部1发射出去。其中所述辐射部1与所述移相器3不直接连接，所述信号通过接地板20上的通孔2耦合至辐射部1。
当天线装置从所述终端设备外部接收一信号时，所述信号由多个辐射部1输入四个天线单元。四个辐射部1将接收的信号通过通孔2耦合至移相器3上，通过移相器3调整信号的接收相位。将调整相位后的信号通过功率衰减器4，所述功率衰减,4加载道尔夫-切比雪夫算法或泰勒算法，对接收的信号功率做相应的衰减。在将衰减后的多路信号发送至功分器80中，此时功分器80会将四路信号合并成一路信号。
本申请的优点在于，本申请通过在阵列天线的每一天线单元中增加一功率衰减器，所述功率衰减器用于加载道尔夫-切比雪夫算法和/或泰勒算法对输入的信号功率做衰减，能有效抑制阵列天线的副瓣增益，并且保持相同的主瓣增益和宽度。
