本申请要求在2020年09月07日提交中国专利局、申请号为202010929217.6、申请名称为“一种控制天线极化方向的方法和天线***”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
本申请涉及通信技术领域,尤其涉及一种控制天线极化方向的方法和天线***。
在高速运动的航天器上,一般采用圆极化天线,使得航天器可在任意状态下接收到信号而在飞行设备上,圆极化天线不但可减小信号的漏失、衰减,而且能消除电离层由法拉第旋转导致的极化畸变影响,移动通信中利用极化分集方式降低多径衰落。而在地面的通信***中,则多采用线极化的形式,如基站采用+/-45°线极化天线。
随着星地融合通信的发展,单一终端与星载设备、地面基站等均存在通信需求,因此单一终端的天线支持任意极化的功能成为迫切需求。
发明内容
本申请提供一种控制天线极化方向的方法和天线***,用以实现单个终端的天线支持任意极化的功能。
第一方面,提供一种天线***,包括至少一个处理器、第一馈源阵列、第二馈源阵列以及第三平面阵列,第一馈源阵列的极化方向与第二馈源阵列的极化方向正交,第三平面阵列用于反射或透射来自第一馈源阵列和第二馈源阵列的波束;至少一个处理器可以用于:控制第一馈源阵列的波束的相位中心在第一位置、波束宽度为第一宽度,控制第二馈源阵列的波束的相位中心在第二位置、波束宽度为第二宽度,控制第一馈源阵列的波束与第二馈源阵列的波束的相位差为第一相位差,在这种情况下,第三平面阵列用于对第一馈源阵列的波束和第二馈源阵列的波束进行反射或透射后,形成第一极化方向的波束;至少一个处理器还可以还用于:对第一馈源阵列和/或第二馈源阵列的波束的相位中心、第一馈源阵列和/或第二馈源阵列的波束的波束宽度、第一馈源阵列的波束与第二馈源阵列的波束的相位差中的一项或多项进行调整,在这种情况下,第三平面阵列对第一馈源阵列调整后的波束和第二馈源阵列调整后的波束进行反射或透射后,可以形成第二极化方向的波束;其中,第一极化方向与第二极化方向不同。
本申请实施例提供的天线***通过调节双馈源阵列(即第一馈源阵列、第二馈源阵列)的波束宽度、相位中心或相位差等,可以调整第三平面阵列的波束的极化方向,进而发射任意极化方向的波束,能真正地支持任意极化切换。相比于现有技术,无需机械旋转馈源或重构反射阵单元极化,实现方式简单、成本低,更便于投入实际中使用。
一种可能的实施方式中,双馈源阵列可以采用双线极化馈源阵列,例如第一馈源阵列 的极化方向为水平极化方向,第二馈源阵列的极化方向为垂直极化方向;双馈源阵列也可以采用双圆极化馈源阵列,例如第一馈源阵列的极化方向为左旋圆极化方向,第二馈源阵列的极化方向为右旋圆极化方向。
应理解,以上两种实现方式仅为举例而非限定,实际应用中不排除其他实现方式的可能性。
一种可能的实施方式中,第一极化方向为线极化、圆极化或椭圆极化中的任意一种,第二极化方向为线极化、圆极化或椭圆极化中的任意一种。
应理解,第一极化方向与第二极化方向的极化类型可以相同也可以不同,本申请不做限制。例如,第一极化方向是线极化,第二极化方向是圆极化或椭圆极化,则第一极化方向与第二极化方向的极化类型相同;或者,例如,第一极化方向是水平极化,第二极化方向是垂直极化,则第一极化方向与第二极化方向的极化类型不同。
一种可能的实施方式中,至少一个处理器在对第一馈源阵列和/或第二馈源阵列的波束的相位中心进行调整时,具体可以通过波束扫描实现。例如,控制第一馈源阵列执行波束扫描,使第一馈源阵列的波束的相位中心偏转;和/或,控制第二馈源阵列执行波束扫描,使第二馈源阵列的波束的相位中心偏转。
而波束扫描,可以通过电控的方式实现。
如此,便可以通过电控方式控制双馈源阵列的相位中心发生偏转,进而控制双馈源阵列波束的增益,进而得到任意极化所需要的幅度值,使得天线***支持任意极化方向。
一种可能的实施方式中,至少一个处理器在对第一馈源阵列和/或第二馈源阵列的波束的波束宽度进行调整时,具体可以通过打开或关闭阵列单元实现。例如,控制第一馈源阵列关闭或打开至少一个单元;和/或,控制第二馈源阵列关闭或打开至少一个单元。其中,第一馈源阵列和/或第二馈源阵列打开的单元的数量越多,波束越窄,反之,第一馈源阵列和/或第二馈源阵列关闭的单元的数量越多,波束越宽。
而阵列单元的打开或关闭,可以通过电控的方式实现。
如此,便可以通过电控方式控制双馈源阵列的波束宽度发生变化,进而控制双馈源阵列波束的增益,进而得到任意极化所需要的幅度值,使得天线***支持任意极化方向。
一种可能的实施方式中,第三平面阵列的每个单元的第一方向上加载有可调相位器件;至少一个处理器在对第一馈源阵列的波束与第二馈源阵列的波束的相位差进行调整时,具体可以是调整每个单元的可调相位器件的电参数(如电流、电压、电容等),电参数用于控制第三平面阵列的单元的形状和/或大小(如电长度)。
当电参数改变时,阵列单元的形状和/或大小会发生改变。而波束经过不同形状和/或大小的阵列单元出射后,相位发生不同程度的改变,因而调节可调相位器件的电参数可以实现对第一馈源阵列和/或第二馈源阵列的相位的补偿,进而达到调整第一馈源阵列与第二馈源阵列的相位差的效果,进而实现形成任意椭圆极化。
一种可能的实施方式中,至少一个处理器还可以用于:在对第一馈源阵列和/或第二馈源阵列的波束的相位中心、第一馈源阵列和/或第二馈源阵列的波束的波束宽度、第一馈源阵列的波束与第二馈源阵列的波束的相位差中的一项或多项进行调整之前,检测第一馈源阵列的波束的幅度和相位、第二馈源阵列的波束的幅度和相位,确定第一馈源阵列和/或第二馈源阵列的波束的相位中心的调整系数,或者确定第一馈源阵列和/或第二馈源阵列的波束的波束宽度的调整系数,或者确定第一馈源阵列的波束与第二馈源阵列的波束的相位差 的调整系数。
这样,处理器在对相位中心、波束宽度、相位差等参数调整时,就可以根据对应的调整系数进行精准调控。
第二方面,本申请实施例提供一种天线***,包括至少一个处理器、第一馈源阵列、第二馈源阵列以及第三平面阵列,第一馈源阵列的极化方向与第二馈源阵列的极化方向正交,第三平面阵列用于反射或透射来自第一馈源阵列和第二馈源阵列的波束;至少一个处理器可以用于:当第三平面阵列接收第一极化方向的波束时,控制第一馈源阵列的波束的相位中心在第一位置、波束宽度为第一宽度,控制第二馈源阵列的波束的相位中心在第二位置、波束宽度为第二宽度,控制第一馈源阵列的波束与第二馈源阵列的波束的相位差为第一相位差,在这种情况下,第三平面阵列对第一极化方向的波束进行反射或透射后,可以形成第一波束和第二波束,并分别由第一馈源阵列和第二馈源阵列接收;至少一个处理器还可以用于:当第三平面阵列接收第二极化方向的波束时,对第一馈源阵列和/或第二馈源阵列的波束的相位中心、第一馈源阵列和/或第二馈源阵列的波束的波束宽度、第一馈源阵列的波束与第二馈源阵列的波束的相位差中的一项或多项进行调整,在这种情况下,第三平面阵列对第二极化方向的波束进行反射或透射后,可以形成第三波束和第四波束,并分别由第一馈源阵列和第二馈源阵列接收;其中,第一极化方向与第二极化方向不同。
本申请实施例提供的天线***通过调节双馈源阵列(即第一馈源阵列、第二馈源阵列)的波束宽度、相位中心或相位差等,可以调整第三平面阵列的波束的极化方向,进而接收任意极化方向的波束。相比于现有技术,无需机械旋转馈源或重构反射阵单元极化,实现方式简单、成本低,更便于投入实际中使用。
一种可能的实施方式中,双馈源阵列可以采用双线极化馈源阵列,例如第一馈源阵列的极化方向为水平极化方向,第二馈源阵列的极化方向为垂直极化方向;双馈源阵列也可以采用双圆极化馈源阵列,例如第一馈源阵列的极化方向为左旋圆极化方向,第二馈源阵列的极化方向为右旋圆极化方向。
应理解,以上两种实现方式仅为举例而非限定,实际应用中不排除其他实现方式的可能性。
一种可能的实施方式中,第一极化方向为线极化、圆极化或椭圆极化中的任意一种,第二极化方向为线极化、圆极化或椭圆极化中的任意一种。
应理解,第一极化方向与第二极化方向的极化类型可以相同也可以不同,本申请不做限制。例如,第一极化方向是线极化,第二极化方向是圆极化或椭圆极化,则第一极化方向与第二极化方向的极化类型相同;或者,例如,第一极化方向是水平极化,第二极化方向是垂直极化,则第一极化方向与第二极化方向的极化类型不同。
一种可能的实施方式中,至少一个处理器在对第一馈源阵列和/或第二馈源阵列的波束的相位中心进行调整时,具体可以通过波束扫描实现。例如,控制第一馈源阵列执行波束扫描,使第一馈源阵列的波束的相位中心偏转;和/或,控制第二馈源阵列执行波束扫描,使第二馈源阵列的波束的相位中心偏转。
而波束扫描,可以通过电控的方式实现。
如此,便可以通过电控方式控制双馈源阵列的相位中心发生偏转,进而控制双馈源阵列波束的增益,进而得到任意极化所需要的幅度值,使得天线***支持任意极化方向。
一种可能的实施方式中,至少一个处理器在对第一馈源阵列和/或第二馈源阵列的波束 的波束宽度进行调整时,具体可以通过打开或关闭阵列单元实现。例如,控制第一馈源阵列关闭或打开至少一个单元;和/或,控制第二馈源阵列关闭或打开至少一个单元。其中,第一馈源阵列和/或第二馈源阵列打开的单元的数量越多,波束越窄,反之,第一馈源阵列和/或第二馈源阵列关闭的单元的数量越多,波束越宽。
而阵列单元的打开或关闭,可以通过电控的方式实现。
如此,便可以通过电控方式控制双馈源阵列的波束宽度发生变化,进而控制双馈源阵列波束的增益,进而得到任意极化所需要的幅度值,使得天线***支持任意极化方向。
一种可能的实施方式中,第三平面阵列的每个单元的第一方向上加载有可调相位器件;至少一个处理器在对第一馈源阵列的波束与第二馈源阵列的波束的相位差进行调整时,具体可以是调整每个单元的可调相位器件的电参数(如电流、电压、电容等),电参数用于控制第三平面阵列的单元的形状和/或大小(如电长度)。
当电参数改变时,阵列单元的形状和/或大小会发生改变。而波束经过不同形状和/或大小的阵列单元出射后,相位发生不同程度的改变,因而调节可调相位器件的电参数可以实现对第一馈源阵列和/或第二馈源阵列的相位的补偿,进而达到调整第一馈源阵列与第二馈源阵列的相位差的效果,进而实现形成任意椭圆极化。
一种可能的实施方式中,至少一个处理器还可以用于:在对第一馈源阵列和/或第二馈源阵列的波束的相位中心、第一馈源阵列和/或第二馈源阵列的波束的波束宽度、第一馈源阵列的波束与第二馈源阵列的波束的相位差中的一项或多项进行调整之前,检测第一馈源阵列的波束的幅度和相位、第二馈源阵列的波束的幅度和相位,确定第一馈源阵列和/或第二馈源阵列的波束的相位中心的调整系数,或者确定第一馈源阵列和/或第二馈源阵列的波束的波束宽度的调整系数,或者确定第一馈源阵列的波束与第二馈源阵列的波束的相位差的调整系数。

反射阵天线(或透射阵天线)是由馈源+平面阵列组成是一种新型的高增益天线,结合 了经典反射面天线(或透射面天线)和直接辐射阵列天线的优点,可以通过合理设计阵列平面上各个独立单元(即可重构孔径)的反射相位来实现特定形状或指向的远场波束。反射阵天线(或透射阵天线)因其功耗低、重量轻、增益高、成本低、易集成等优势在近些年得到了快速发展,发展出了多种多样的天线形式,具有广阔的应用前景。如图1A所示,为一种可能的反射阵天线的示意图;如图1B所示,为一种可能的透射阵天线的示意图。
在地面的通信***中,设备的天线多采用线极化的形式,如基站采用+/-45°线极化。但在复杂的气候和电磁环境下,这种单一线极化的天线则无法满足如卫星通信、太空侦测和雷达对目标的跟踪定位要求。
为了提高发射、接收天线间的极化效率,避免极化不匹配,具有多极化变换功能的反射阵天线的应用价值就突显出来。例如,在高速运动的航天器上,采用圆极化天线,航天器可在任意状态下接收到信号,而在飞行设备上,圆极化天线不但可减小信号的漏失、衰减,而且能消除电离层由法拉第旋转导致的极化畸变影响。
随着未来星地融合通信的发展,单一终端与星载设备、地面基站等均存在通信需求,单一终端的天线支持任意极化的功能成为迫切需求。
1、机械旋转馈源技术:全极化反射阵中的单元如果是完全对称单元,且馈源全部是线极化入射时,通过调整馈源的角度可以调整馈源的波束的极化方向,进而实现任意极化的天线***。如图2A所示,馈源的角度旋转至0°、45°、90°、135°时,可分别实现水平极化、左旋圆极化、垂直极化和右旋圆极化。
但是,这种方法是通过机械旋转馈源实现线极化和圆极化天线切换,在实际使用中不方便,尤其当天线设计完成的时候,***旋转结构复杂且笨重,实现难度大。
2、重构反射阵单元极化技术:调整反射阵天线中的反射阵面的单元极化特性,可以实现圆极化和线极化的切换。如图2B所示,通过在反射阵单元结构中加多个开关实现反射阵单元极化特性切换,可分别实现线极化和圆极化的天线***,可避免馈源旋转的***复杂性。
但是,重构反射阵单元极化技术目前还没有任意线极化和任意椭圆极化的具体实现方法。并且实际应用中反射阵中的反射阵元数量成百上千,且每个开关均需要控制,这种方法在实际应用中极为不方便,实现难度大。另外,该方法中,如果不改变馈源,则只能是水平极化和垂直极化相互切换,或者是左旋圆极化和右旋圆极化相互切换,存在局限性,并不能真正地支持任意极化切换。
由此可见,虽然机械旋转馈源技术或重构反射阵单元极化技术,可以实现圆极化和线极化可重构,但是机械旋转馈源技术实现任意极化的方式在实际使用中并不方便,而重构反射阵单元极化技术则需要大量的开关和控制线,实现起来也非常复杂。
基于此,本申请实施例提供一种控制天线极化方向的方法和天线***,采用电控的方式调节双线极化或者双圆极化馈源阵列的波束宽度和/或相位中心,从而改变通过周期性可调平面阵列的反射波增益(反射阵)或透射波增益(透射阵),进而可以形成任意线极化或任意圆极化的反射阵或透射阵。进一步的,还可以在可调反(透)射阵面的单元结构上加载可调相位器件(如变容二极管或可调电容等),对双线极化或者双圆极化馈源阵列发出的波束的相位进行补偿,达到调节双线极化或者双圆极化馈源阵列的相位差的效果,进而形成任意椭圆极化。
应理解,本申请实施例可以应用于各种设备,例如可以应用于未来星地融合通信中所 需任意极化的终端、基站或星载设备等。
例如,参见图3A,为本申请实施例的一种可能的应用场景,支持任意极化的天线***用于车载或家庭终端。其中,基站的天线***是线极化,卫星的天线***是圆极化,而车载终端、家庭终端的天线***则支持任意极化,使得车载终端、家庭终端等既可以以线极化的方式与基站通信,又可以以圆极化的方式与卫星通信。
例如,参见图3B,为本申请实施例的另一种可能的应用场景,支持任意极化的天线***用于基站和卫星。其中,基站、卫星的天线***支持任意极化方式,使得基站、卫星能够与任一极化方式的设备通信,例如以线极化方式与基站通信,以圆极化或线极化的方式与家庭终端通信等。
当然,图3A和图3B仅仅是对本申请应用场景的两种示例而非限定,在实际应用中不排除还有其它应用场景的可能性。
为了使本申请实施例的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施例的技术方案作进一步地详细描述。
本申请实施例中的术语“***”和“网络”可被互换使用。“至少一个”是指一个或者多个,“多个”是指两个或两个以上。“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B的情况,其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合,例如a、b或c中的至少一项(个),可以表示:a,或b,或c,或a和b,或b和c,或a和c,或a和b和c。
以及,除非有相反的说明,本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分,不用于限定多个对象的顺序、时序、优先级或者重要程度。例如,第一优先级准则和第二优先级准则,只是为了区分不同的准则,而并不是表示这两种准则的内容、优先级或者重要程度等的不同。
此外,本申请实施例和权利要求书及附图中的术语“包括”和“具有”不是排他的。例如,包括了一系列步骤或模块的过程、方法、***、产品或设备,不限定于已列出的步骤或模块,还可以包括没有列出的步骤或模块。
如图4所示,为本申请实施例提供的一种天线***的结构示意图。该天线***包括至少一个处理器41(图4以一个处理器41为例)、双馈源阵列42以及第三平面阵列43。双馈源阵列42进一步包括第一馈源阵列421、第二馈源阵列422,且第一馈源阵列421的极化方向与第二馈源阵列422的极化方向正交。
一种可能的设计中,双馈源阵列42为双圆极化阵列。第一馈源阵列421的极化方向为左旋圆极化方向、第二馈源阵列422的极化方向为右旋圆极化方向;或者,第二馈源阵列421的极化方向为左旋圆极化方向、第一馈源阵列421的极化方向为右旋圆极化方向。
另一种可能的设计中,双馈源阵列42为双线极化阵列。第一馈源阵列421的极化方向为水平极化方向、第二馈源阵列422的极化方向为垂直极化方向;或者,第一馈源阵列421的极化方向为垂直极化方向、第二馈源阵列422的极化方向为水平极化方向。
当然,以上两种仅是对第一馈源阵列421的极化方向与第二馈源阵列422的极化方向的举例而非限定,在实际应用中不排除其他实现方式的可能性。
一种可能的设计中,第三平面阵列43是透射阵列。在天线***发射波束时,来自第 一馈源阵列421的波束a和第二馈源阵列422的波束b经由第三平面阵列43透射后形成波束c向外发送;在天线***接收波束时,来自外界的波c束经由第三平面阵列43透射后形成波束a、b,分别由第一馈源阵列421和第二馈源阵列422接收。
另一种可能的设计中,第三平面阵列43是反射阵列。在天线***发射波束时,来自第一馈源阵列421的波束a和第二馈源阵列422的波束b经由第三平面阵列43反射后形成波束c向外发送;在天线***接收波束时,来自外界的波c束经由第三平面阵列43反射后形成波束a、b,分别由第一馈源阵列421和第二馈源阵列422接收。
为了便于描述,在下文中,主要以第三平面阵列43是反射阵列为例。如图4所示,第三平面阵列43对波束a、b进行反射后形成合成波束c。
继续参见图4,处理器41与第一馈源阵列421和第二馈源阵列422分别电连接,进而处理器41可以向第一馈源阵列421和第二馈源阵列422发送控制指令,进而控制第一馈源阵列421的波束和第二馈源阵列422的波束的相位中心、波束宽度。
可选的,处理器41还可以控制第一馈源阵列421的波束和第二馈源阵列422的波束的初始相位差(即调整波束a、b在双馈源阵列42射出时的相位差)。
可选的,处理器41还可以与第三平面阵列43电连接,进而可以控制第三平面阵列中各阵列单元(本文中又将“阵列单元”简称为“单元”)对入射波束(即入射到各单元的波束)的相位调制参数,进一步对第一馈源阵列421的波束和/或第二馈源阵列422的波束的相位进行补偿,调整波束a、b从双馈源阵列42射出后在第三平面阵列43处的相位差。
处理器41通过控制双馈源阵列42的相位中心、波束宽度或相位差中的一项或多项,使得天线***可以向外界发射任意极化方向的波束或者从外界接收任意极化方向的波束。
下面介绍双馈源阵列42为双线极化时实现任意极化原理。
对于正交放置的两个线极化波以Z方向为传播方向,极化方向分别为X方向和Y方向合成电场可以符合下述公式:
有以下几种情况:
所以,两个正交放置的线极化波可以通过幅度和相位控制得到任意线极化波,圆极化波和椭圆极化波。
请参见图5A,为两个正交的线极化波实现任意线极化波的原理图。请参见图5B,为双线极化合成任意极化实现框图。表1是图5B所示实现框图中几种控制方式下的合成极化示例。
表1
下面介绍双馈源阵列42为双圆极化时实现任意极化原理。
对于重叠放置的两个圆极化波以Z方向为传播方向,极化方向分别为X方向和Y方向合成电场可以符合公式:
所以,两个重叠放置的圆极化波能够通过幅度控制得到任意线极化波,椭圆极化波和圆极化波。
请参见图6,为双圆极化合成任意极化实现框图。表2是图6所示实现框图中几种控制方式下的合成极化示例。应理解,图6是以
(初始相位差)通过垂直极化通道上的移相控制2控制为例,实际还可以将
放在水平极化通道上控制,本申请对此不做限定。
表2
下面介绍天线(波束)的相位中心。
天线所辐射出的电磁波在离开天线一定的距离后,其等相位面会近似为一个球面,该球面的球心即为该天线的等效相位中心,波束指向不一致,相位中心会发生一定的变化。
对于反(透)射阵天线涉及到的相位中心是指馈源阵列同反射阵列之间的距离,如图7所示。表3给出了不同F/D的值对应的增益值。从表3可以看出,F/D等于0.5的反射阵天线,其增益为最大,当相位中心改变时,增益变化。
表3
F/D | 0.1 | 0.2 | 0.3 | 0.4 | 0.5 | 0.6 | 0.7 | 0.8 | 0.9 | 1 |
增益(dB) | 13.15 | 13.8 | 15.45 | 19.16 | 20.98 | 20.3 | 17.95 | 16.41 | 15.38 | 13 |
下面介绍天线***口径效率和相位中心、波束宽度之间的关系。
对同一个反射阵面,不同的口径效率(口径效率是指天线的有效口径和物理口径的比值)对应不同的天线增益,进而影响不同波束电场值,因此可以得到任意线极化或者椭圆极化所需要的幅度值。对于每个设计好的天线***来说,天线的口径效率同馈源阵列的相位中心和馈源的波束宽度有关。
参见图8A,为不同相位中心(theta)对应不同口径效率的示意图。可以看出,口径效率随着相位中心的变化而变化,相位中心在40°左右时,增益最大,口径效率在小于或大于40°的方向上递减。
参见图8B,为不同馈源波束宽度对应不同口径效率的示意图。可以看出,馈源1波束宽度>馈源2波束宽度>馈源3波束宽度,而馈源3口径效率>馈源2口径效率>馈源1口径效率。
通过上述(图5A~图5B、图6~图7、图8A~图8B所示实施例的)相关介绍可知,处理器41控制第一馈源阵列421和/或第二馈源阵列422的相位中心的改变,可以导致口径效率的变化,进而改变第三平面阵列43反(或透)射波的波束幅度,即改变相位中心可以改变任意极化所需的幅度变化。处理器41控制第一馈源阵列421和/或第二馈源阵列422的波束宽度改变,也可以导致口径效率变化,进而改变第三平面阵列43反(透)射波的波束幅度,即改变波束宽度改变任意极化所需的幅度变化。因此,本申请实施例中,处理器41通过控制双馈源阵列42的相位中心和/或波束宽度可以控制任意极化所需的幅度变化,进而实现任意线极化或圆极化。
对于第一馈源阵列421与第二馈源阵列422的相位差的控制,可以由第一馈源阵列421与第二馈源阵列422对应的射频通道上设置移相控制模块实现(如图5B、图6所示),进而实现形成任意椭圆极化。除此之外,还可以在第三平面阵的阵列单元上加载可调相位器件(如变容二极管或可调电容或其他可调电位等),通过控制可调相位器件的电参数(如电流、电压、电容等),进而控制第三平面阵列中各单元对波束(即入射到各单元的波束)的相位调制参数(例如单元的形状和/或大小),进而实现对第一馈源阵列421和/或第二馈源阵列422的相位的补偿,达到调整第一馈源阵列421与第二馈源阵列422的相位差的效果,进而实现形成任意椭圆极化。
如图9所示,为在第三平面阵列的阵列单元的x方向上加载可调电容的示意图。其中,馈源阵列42为双圆极化时,阵列单元的形状为矩形,馈源阵列42为双线极化时,阵列单元的形状为十字形(当然这里仅为举例,实际还可以是其它形状)。通过调整可调电容的 电容值,可以增大或减小阵列单元在x方向上的长度,进而改变阵列单元的尺寸,进而对入射到单元的波束的相位进行调整。
上面介绍了本申请实施例提供的天线***形成任意极化的原理,以下介绍本申请实施例提供的天线***向外界发射波束的方法。
如图10所示,为本申请实施例提供的一种控制天线极化方向的方法,可以应用于图4所示天线***,方法包括:
S1001、当第三平面阵列43需要发射第一极化方向的波束时,处理器41控制第一馈源阵列421发射波束的相位中心在第一位置、波束宽度为第一宽度,控制第二馈源阵列422发射波束的相位中心在第二位置、波束宽度为第二宽度,以及控制第一馈源阵列发射波束与第二馈源阵列发射波束的相位差为第一相位差,进而第一馈源阵列发射的波束a1和第二馈源阵列发射的波束b1经第三平面阵列43反射后,形成第一极化方向的波束c1。
应理解,本文中极化方向包括圆极化、线极化(包括水平极化、垂直极化以及其它方向的线极化)、椭圆极化等类型。这里的第一极化方向可以是圆极化、线极化或椭圆极化的中任意一种。
其中,第一极化方向与相位中心、波束宽度、相位差的对应关系可以根据上文相关介绍得到,此处不再赘述。
S1002、当第三平面阵列43需要发射第二极化方向的波束时,处理器41对双馈源阵列42的相位中心、双馈源阵列42的波束宽度、第一馈源阵列421和第二馈源阵列422的相位差中的一项或多项进行调整,进而第一馈源阵列发射的波束a2和第二馈源阵列b2发射的波束经第三平面阵列43反射后,形成第二极化方向的波束c2;其中,第一极化方向与第二极化方向不同。
应理解,由于第一馈源阵列421和第二馈源阵列422可以看成一个整体,即双馈源阵列42,所以处理器41调整第一馈源阵列421和第二馈源阵列422中任一馈源阵列的波束的相位中心或波束宽度,也可以认为是处理器41是调整双馈源阵列42(第一馈源阵列421和第二馈源阵列422)的波束的相位中心或波束宽度。换而言之,处理器41可以对第一馈源阵列421和/或第二馈源阵列422的波束的相位中心、第一馈源阵列和/或第二馈源阵列的波束的波束宽度、第一馈源阵列的波束与第二馈源阵列的波束的相位差中的任意一项或多项进行调整。
其中,第二极化方向与相位中心、波束宽度以及相位差的对应关系可以根据上文相关介绍得到,此处不再赘述。
应理解,第一极化方向与第二极化方向的极化类型可以相同也可以不同,这里不做限制。例如,第一极化方向是线极化,第二极化方向是圆极化或椭圆极化,极化类型相同。例如,第一极化方向是水平极化,第二极化方向是垂直极化,极化类型不同。
以下介绍本申请实施例提供的天线***从外界接收波束的方法。
天线***从外界接收波束是向外界发射波束的逆过程,其控制极化方向方式的原理类似。如图11所示,为本申请实施例提供的另一种控制天线极化方向的方法,可以应用于图4所示天线***,方法包括:
S1101、当第三平面阵列43需要接收第一极化方向的波束时,处理器41控制第一馈源阵列421接收波束的相位中心在第一位置、波束宽度为第一宽度,控制第二馈源阵列422接收波束的相位中心在第二位置、波束宽度为第二宽度,控制第一馈源阵列421接收波束 与第二馈源阵列422接收波束的相位差为第一相位差,使得第三平面阵列43对第一极化方向的波束c1进行反射或透射后所形成的第一波束a1和第二波束b1能够分别被第一馈源阵列和第二馈源阵列接收。
S1102、当第三平面阵列43需要接收第二极化方向的波束时,处理器41对第一馈源阵列421和/或第二馈源阵列422的接收波束的相位中心、第一馈源阵列和/或第二馈源阵列的接收波束的波束宽度、第一馈源阵列的接收波束与第二馈源阵列的接收波束的相位差中的一项或多项进行调整,使得第三平面阵列43对第二极化方向的波束c2进行反射或透射后所形成的第三波束a2和第四波束b2能够分别被第一馈源阵列421和第二馈源阵列422接收;其中,第一极化方向与第二极化方向不同。
应理解,在实际应用中,单个天线***(或单个设备)可以仅用于实现图10所示的发送方法或图11所示的接收方法,也可以既用于实现图10所示的发送方法又用于实现图11所示的接收方法,本申请不做限制。
可选的,在本申请实施例中,处理器41在对第一馈源阵列421和/或第二馈源阵列422的波束的相位中心进行调整时,具体可以是:控制第一馈源阵列421执行波束扫描,使第一馈源阵列421的波束的相位中心偏转;和/或,控制第二馈源阵列422执行波束扫描,使第二馈源阵列422的波束的相位中心偏转。
采用正交双线(或双圆)极化多波束的相控阵天线,通过波束扫描控制不同极化的波束指向,导致双馈源阵列42不同的相位中心,而反射阵天线设计完成后其馈源物理位置固定。因此不同的相位中心,在相同的物理位置上所形成口径效率是不一样的。即不同相位中心所对应的电场幅度不一样。正如上文所述,对于正交线极化波可以合成任意极化的线极化波,在此基础上,通过控制反射阵阵元上可调电容或者可调电路调节相位差,实现任意椭圆极化。
示例性的,图12为不同相位中心馈源阵列形成任意极化波束的示意图。应理解,图12分别示出了波束a、b对应的反射波束a’、b’,但实质上波束a’、b’可以是一个合成波束,即反射波束a’、b’指向同一位置时可以合成波束c,合成效果可以参考图4。
图13为馈源波束扫描时相位中心变化示意图,馈源波束扫描时相位中心发生变化,当馈源波束指向14°时,相位中心Z:34mm,馈源波束指向6°时,相位中心Z:21mm。
可选的,在本申请实施例中,处理器41在对第一馈源阵列421和/或第二馈源阵列422的波束的波束宽度进行调整时,具体可以是:控制第一馈源阵列421关闭或打开至少一个单元;和/或,控制第二馈源阵列422关闭或打开至少一个单元。
其中,第一馈源阵列421和/或第二馈源阵列422打开的单元的数量越多,波束越窄,反之,第一馈源阵列421和/或第二馈源阵列422关闭的单元的数量越多,波束越宽。
采用正交双线(或双圆)极化多波束的相控阵天线,如双馈源阵列42采用正交双线极化多波束相控阵天线,由任意角度线极化得到正交极化波束的增益,进而计算出不同的口径效率,不同的口径效率对应不同的波束增益,即不同的波束宽度的馈源。通过得到的不同馈源波束宽度,对馈源的端口的幅度进行加权,控制第一馈源阵列421和/或第二馈源阵列422打开的单元的数量。
如图14所示,为不同馈源波束宽度合成任意极化的示意图,馈源阵列421波束a的宽度大于馈源阵列422波束b的宽度,因此可得反射阵形成的增益大小不一样。应理解,图14分别示出了波束a、b对应的反射波束a’、b’,但实质上波束a’、b’可以是一个合成波束, 即反射波束a’、b’指向同一位置时可以合成波束c,合成效果可以参考图4。
可选的,处理器41在对第一馈源阵列421和/或第二馈源阵列422的波束的相位中心、第一馈源阵列421和/或第二馈源阵列422的波束的波束宽度、第一馈源阵列421的波束与第二馈源阵列422的波束的相位差等进行调整时,处理器41可以先检测第一馈源阵列421和第二馈源阵列422当前波束的幅度和相位,然后根据第一馈源阵列421和第二馈源阵列422当前波束的幅度和相位,以及第一馈源阵列421和第二馈源阵列422所需调整到的波束的幅度和相位(即调整要求),确定第一馈源阵列421和/或第二馈源阵列422的波束的相位中心或波束宽度或相位的调整系数,进而基于这些调整系数进行相应调整,进而提高调整的准确性。
进一步可选的,在每执行一次调整后,处理器41检测第一馈源阵列421和第二馈源阵列422调整后的波束的幅度和相位是否满足调整要求,若不满足,则继续调整,直至第一馈源阵列421和第二馈源阵列422的波束的幅度和相位满足调整要求为止,进而进一步提高调整的准确性。
进一步需要说明的是,图4仅为本申请实施例中天线***关键部件的示例,在实际应用中天线***还可以进一步包括其他部件。例如,参见图15所示,处理器41具体为基带处理器,处理器41与第一馈源阵列421的射频通道上还包括数/模(或模/数)转换器44a、变频器45a、功率放大器46a;处理器41与第二馈源阵列422的射频通道上还包括数/模(或模/数)转换器44b、变频器45b、功率放大器46b。
本申请实施例通过设置双线极化或双圆极化的双馈源阵列42,并采用电控的方式调节双线极化或者双圆极化馈源阵列42的波束宽度和/或相位中心,使得天线***可以形成任意线极化或任意圆极化的波束,进一步在第三平面阵列43的单元结构上加载可调相位器件,可以形成任意椭圆极化。不仅能够真正地支持任意极化切换,而且无需机械旋转馈源或重构反射阵单元极化,实现方式简单、成本低,更便于投入实际中使用。
以上各实施例可以相互结合以实现不同的技术效果。
