Description

带有介电移相器的串行馈送相控阵天线
对于有关专利申请的交叉参考
本申请要求提出于1999年9月14日的美国临时专利申请No.60/153,859的权益。
发明领域
本发明一般涉及相控阵天线，更具体地说，涉及带有共面波导(CPW)电压调谐移相器的微波传输带补片(patch)天线。
相控天线是指带有发射相控信号以形成一个无线电束的大量辐射元件的天线。无线电信号能电子地由各个天线元件的相对相控的主动操纵控制。电子束控制概念适用于与发射机和接收机一起使用的天线。电子扫描相控阵天线与其机械对应物相比在速度、精度、和可靠性方面是优越的。用电子扫描天线中的电子移相器替换在机械扫描天线中的万向接头，通过更迅速和准确的目标识别增加了天线用在防御系统中的生命力。借助于相控阵天线系统也能迅速和准确地操纵复杂的跟踪练习。
移相器在相控阵天线的操作中起关键作用。电气控制移相器能利用可调谐铁电材料，其电容率(更普遍地叫做介电常数)能通过改变材料经受的电场强度而改变。即使这些材料工作在其高于居里温度的顺电相中，它们也便利地叫做“铁电的”，因为它们在低于居里温度的温度下呈现同时极化。包括钡-锶钛酸盐(BST)或BST合成物的可调谐铁电材料已经是几个专利的主题。
包括钡锶钛酸盐的介电材料公开在授予Sengupta等的、标题为“陶瓷铁电材料”的美国专利No.5,312,790；授予Sengupta等的、标题为“陶瓷铁电合成材料-BSTO-MgO”的美国专利No.5,427,988；授予Sengupta等的、标题为“陶瓷铁电合成材料-BSTO-ZrO2”的美国专利No.5,486,491；授予Sengupta等的、标题为“陶瓷铁电合成材料-BSTO镁基合成物”的美国专利No.5,635,434；授予Sengupta等的、标题为“多层铁电合成波导管”的美国专利No.5,830,591；授予Sengupta等的、标题为“薄膜铁电合成物及制造方法”的美国专利No.5,846,893；授予Sengupta等的、标题为“制造薄膜合成物的方法”的美国专利No.5,766,697；授予Sengupta等的、标题为“电子分级的多层铁电合成物”的美国专利No.5,693,429；及授予Sengupta的、标题为“陶瓷铁电合成材料-BSTO-ZnO”的美国专利No.5,635,433中。这些专利通过参考包括在这里。由Sengupta提出于2000年6月15日的、标题为“包括可调谐介电和金属硅酸盐相的电子可调谐陶瓷材料”的共同待决、共同授予美国专利申请公开了另外的可调谐介电材料，并且也通过参考包括。在这些专利中表示的材料，特别是BSTO-MgO合成物表现出低介电损失和高可调谐性。把可调谐性定义为介电常数随施加电压的相对变化。
使用铁电材料的可调谐移相器公开在美国专利No.5,307,033、5,032,805、及5,561,407中。这些移相器包括铁电基片作为相位调制元件。铁电基片的电容率能通过改变施加到基片上的电场强度而改变。当RF信号通过移相器时，基片的电容率调谐导致相位移动。公开在这些专利中的铁电移相器具有高导体损失、高模式、直流偏压、及在K(18至27GHz)和Ka(27至40GHz)频带下的阻抗匹配问题的缺点。
一种已知类型的移相器是微波带状线路移相器。利用可调谐介电材料的微波带状线路移相器表示在美国专利No.5,212,463；5,451,567及5,479,139中。这些专利公开了载有一种电压可调谐铁电材料的微波带状线路，以改变引导的电磁波的传播速度。美国专利No.5,561,407公开了一种由松散陶瓷制造的微波传输带调谐移相器。松散微波传输带移相器具有需要较高偏电压、复杂制造处理及高成本的缺点。
共面波导管也能用作移相器。美国专利No.5,472,935和6,078,827公开了其中高温超导材料的导体安装在一种可调谐介电材料上的共面波导管。这种器件的使用需要冷却到较低温度。另外，美国专利No.5,472,935及6,078,827讲授了具有高Sr比率的SrTiO3、或(Ba、Sr)TiO3的可调谐膜的使用。SrTiO3、和(Ba、Sr)TiO3具有高介电常数，这导致低特征阻抗。这使得必须把低阻抗移相器变换到普通使用的50欧姆阻抗。
美国专利No.5,617,103公开了一种利用铁电移相元件的铁电移相天线阵列。在该专利中公开的天线利用一种其中一个铁电移相器集成在带有多个补片天线的单个基片上的结构。采用电子移相器的相控阵天线的另外例子能在美国专利No.5,079,557；5,218,358；5,557,286；5,589,845；5,917,455；及5,940,030中找到。
希望具有一种利用低成本移相器的相控阵天线，该移相器能在室温下和高频，如高于Ku频带(12至18GHz)，下操作。这能起重要作用，有助于使电子扫描相控阵天线实用于工业用途。
本发明概述
一种相控阵天线包括：多个辐射元件；一个馈电线组件；一个接地平面，定位在多个辐射元件与馈电线组件之间，使接地平面具有定位在多个辐射元件与馈电线组件之间的多个开口；及多个电压可调谐介电移相器，耦合到馈电线组件上。
按照本发明建造的天线利用低损失可调谐薄膜介电元件，并且能在宽频率范围上操作。形成共面波导管的导体在室温下操作。这里的设备在设计上是独特的，并且即使在以上Ku频带(12至18GHz)中的频率下也呈现低插入损失。

本发明的详细描述
本发明的最佳实施例是一种包括电压调谐共面波导管(CPW)移相器和圆偏振孔径耦合微波传输补片元件的电气扫描相控阵天线。CPW移相器包括电压调谐介电膜，其介电常数(电容率)可以通过改变施加到其上的电场强度而改变。当射频(RF)信号通过CPW线时，基片的电容率调谐导致移相。膜能通过标准厚/薄膜过程沉积到低介电损失和高化学稳定性基片上，如MgO、LaAlO3、蓝宝石、Al2O3、及各种陶瓷基片。
参照附图，图1是带有按照本发明一个实施例建造的一个串行馈电列的补片元件的孔径耦合微波传输带天线10的分解图。该天线包括方形微波传输带补片12的形式的多个辐射元件。微波传输带补片构造在正常低介电常数材料14上，如Rohacell泡沫上。泡沫具有大厚度(＞2mm)以提供宽带宽。通常较厚的泡沫产生较宽的带宽。然而，厚泡沫使效率变坏。典型的泡沫厚度约是波长的12.5％至25％。方形补片12的对称性有助于保持天线的圆偏振。微波传输带补片元件经带有多个孔径20的接地平面18耦合到一个馈电组件16上。接地平面最好由铜制造。孔径是细长的，即，它们在一个方向上比在垂直方向上长。在该最佳实施例中，孔径是矩形的。能使用其它孔径形状。具体孔径的选择取决于带宽和加工公差。孔径以正交对排列，从而在每对中孔径的主轴彼此基本上以90°角布置以实现圆偏振。
馈电组件16包括一个耦合到线性微波带状线路24上的共面波导管22，两者都安装在基片26的底部上。多个辅助微波带状线路28基本上从线性微波带状线路24垂直地延伸。辅助微波带状线路的每一个弯曲，从而它位于孔径一对的下面。共面波导管包括一个耦合到中央带状线32上的输入30、和定位在中央带状线32上并且由间隙38和40与中央带状线32分离的一对接地平面电极34和36。在共面波导管端部处的一个过渡部分42把波导管耦到微波带状线路24上。为了在基片上形成导体图案，两侧都初始涂有铜。蚀刻处理用来得到在金属片18和基片16的底侧上看到的特定图案。在馈电组件中的微波带状线路通常具有50欧姆的特征阻抗。然而，共面波导管移相器具有约20欧姆的特性。阻抗匹配是必需的以转换该差别。导体34和36的锥形端部把共面波导管移相器转换到50欧姆。然后50欧姆共面波导管耦合到50欧姆微波带状线路上。
图1表示带有一个串行馈电列的补片元件的孔径耦合微波传输带天线。微波传输带补片元件是具有引导RF信号的波长的近似一半的长度，并且构造在低介电常数厚(＞2mm)材料上，如Rohacell泡沫上。方形补片的对称性有助于保持圆偏振。由于圆偏振能通过以相位正交激励两个正交补片模式产生圆偏振，所以每个微波传输带补片由具有彼此90°相位差的两个正交槽馈电以创建圆偏振。在蚀电基片上的一个垂直弯曲微波带状线路，具有约2至3的介电常数，馈电到两个孔径。在两个正交槽之间的微波带状线路的长度引起90°相位差。图2是图1的天线辐射元件的俯视图。
图3表示带有五个共面移相器48和一个5×5阵列补片辐射元件50安装在基片52上的馈电组件46的相控阵天线44的结构。接地平面54包括把来自馈电组件46的信号耦合到辐射元件50上的多个成对正交孔径56。馈电组件包括与图1中所示那些类似的多个共面波导管和带状线。天线44是由铁电CPW移相器控制的圆偏振孔径耦合合微波传输带天线的一个例子。一个CPW移相器控制每列微波传输带补片的相位以得到两维扫描。
图4是能用在按照本发明建造的相控阵天线中的一个30GHz 360°共面波导移相器组件60的俯视图。图5是沿线5-5得到的、图4的移相器组件60的剖视图。移相器构造在具有300左右介电常数(电容率)和10微米厚度的可调谐介电膜80上。膜沉积在一个低介电常数(～10)基片90上。膜的厚度依据沉积方法能从0.5至10调节。而且，提供室温沉积的其它处理能用来把膜直接沉积到基片上。
组件60包括一个主共面波导管62，该波导管62包括一条中心线64和由间隙70和72与中心线隔离的一对接地平面导体66和68。共面波导管的中心部分74具有20欧姆左右的特征阻抗。两个锥形匹配部分76和78定位在波导管的端部处，并且形成阻抗转换器以把20欧姆阻抗匹配到50欧姆阻抗上。共面波导管62定位在一层可调谐介电材料80上。导电电极66和68也布置在可调谐介电层上，并且成CPW接地平面。辅助接地平面电极82和84也定位在可调谐介电材料80的表面上。电极82和84也绕图5中所示的波导管的边缘延伸。电极66和68分别由间隙86和88与电极82和84隔离。间隙86和88阻塞直流电压，从而直流电压能在CPW间隙上偏置。电极66和68的宽度是约0.5mm。对于范围从约200至400的介电常数和MgO基片，中心线宽度和间隙是约10至60微米。可调谐介电材料80定位在低介电常数(约10)基片90的平面表面上，基片90在该最佳实施例中是具有0.25mm厚度的MgO。然而，基片能是其它材料，如LaAlO3、蓝宝石、Al2O3、及其它陶瓷基片。一个金属保持器92沿波导管的底部和侧部延伸。一个偏压源94经电感器96连接到带条64上。
共面波导管和微波带状线的接地平面经基片的侧边缘彼此连接。相位移动由通过跨过共面波导管的间隙施加直流电压调谐的介电常数产生。共面波导管电压调谐移相器利用低损失可调谐介电膜。在最佳实施例中，可调谐介电膜是基于钡锶钛酸盐(BST)的合成陶瓷，具有一个通过施加直流偏压能改变的介电常数，并且能在室温下操作。
用在本发明的移相器的最佳实施例中的可调谐介质具有比常规可调谐材料低的介电常数。介电常数能在20V/μm下变化20％至70％，典型地约50％。偏压的数值随间隙尺寸而变化，并且对于20μm间隙典型地在从约300至400V的范围内。低偏压电平具有多种好处，然而，要求的偏压取决于设备结构和材料。图4和5的移相器设计成具有360°相位移动。介电常数能在从60至600V的范围内，并且典型地从300至500V。在该最佳实施例中，可调谐介质是基于钡锶钛酸盐(BST)的膜，在零偏压下具有约500的介电常数。最佳材料将呈现高调谐和低损失。然而，可调谐材料通常具有较高调谐和较高损失。该最佳实施例利用具有50％左右的调谐、和损失尽可能低的材料，这在24GHz下在(损失角正切)0.01至0.03的范围内。更具体地说，在该最佳实施例中，材料的成分是一种钡锶钛酸盐(BaxSrl-xTiO3、BSTO，其中x小于l)、或具有70至600介电常数、从20至60％调谐范围、及在K和Ka频带下损失角正切为0.008至0.03的BSTO合成物。可调谐介电层可以是一层薄的或厚的膜。拥有要求性能参数的这种BSTO合成物的例子包括，但不限于：BSTO-MgO、BSTO-MgAl2O4、BSTO-CaTiO3、BSTO-MgTiO3、BSTO-MgSrZrTiO6、及其组合。
本发明最佳实施例的K和Ka频带共面波导管移相器构造在一层在零偏压下具有约300至500介电常数(电容率)和10微米厚度的可调谐介电膜上。然而，能使用可调谐介电材料的薄和厚膜。膜仅在CPW区域中以0.25mm的厚度沉积在一个低介电常数基片MgO上。了为这种描述的目的，低介电常数小于25。MgO具有约10的介电常数。然而，基片能是其它材料，如如LaAlO3、蓝宝石、Al2O3、及其它陶瓷。可调谐材料膜的厚度依据沉积方法能从1至15微米调节。对于基片的主要要求是其化学稳定性、在膜燃烧温度(～1200C)下与可调谐膜的反应、以及在操作频率下的介电损失(损失角正切)。
图6是图4的移相器组件42的俯视图，添加有一个偏压拱顶以把偏压连接到接地平面电极66和68上。图7是沿线7-7得到的、图6的移相器组件60的剖视图。拱顶连接共面波导管的两个接地平面，并且覆盖主要波导线。一个电极终端132焊接在拱顶的顶部上以连接直流偏压控制。直流偏压控制电路的另一个终端(未表示)连接到共面波导的中心线64上。为了把偏置直流电压施加到CPW上，使小间隙86和88隔离其中布置直流偏压拱顶的内部接地平面电极66和68、及共面波导管的接地平面(电极82和84)的其它部分(外部)。外部接地平面绕基片的侧部和底部平面延伸。外部或底部接地平面连接到一个RF信号接地平面134上。直流源的正和负电极分别连接到拱顶130和中心线64上。在接地平面中的小间隙作为一个阻塞直流电压的直流阻塞电容器工作。然而，电容应该高得足以允许RF信号通过它。拱顶电气连接到接地平面66和68上。
一个微波带状线路和共面波导管线能连接到一条传输线上。图8是另一种移相器136的俯视图。图9是沿线9-9得到的、图8的移相器的剖视图。图8和9表示微波传输带138线如何转换到共面波导管组件140。微波传输带138包括一个安装在基片144上的导体142。导体142例如通过焊接或粘结连接到共面波导管148的中心导体146上。接地平面导体150和152安装在一种可调谐介电材料154上，并且由间隙156和158与导体146隔离。在表明的实施例中，粘结剂160连接导体142和146。可调谐介电材料154安装在一个不可调谐介电基片162的表面上。基片144和162由一个金属保持器164支撑。
由于在共面波导管中的间隙(＜0.04mm)远小于基片的厚度(0.25mm)，所以几乎所有的RF信号经共面波导管而不是微波带状线路传输。这种结构使得非常容易从共面波导管转换到微波带状线路而不必经或耦合转换。
图10是用于按照本发明建造的一种天线的移相器的等轴测图。一个壳体166建立在偏压拱顶上以覆盖整个移相器，从而只有两个50欧姆微波带状线路暴露以连接到一个外部电路上。只有线168表示在该视图中。
图11是按照本发明建造的、用在相控阵天线中的30GHz共面波导管移相器的一个阵列170的分解等轴测图。一个由绝缘材料制成的和支撑一个偏压网173的偏压线板172用来覆盖移相器阵列和把偏压连接移相器上。把在每个移相器的拱顶上的电极穿过孔174、176、178及180焊接到偏压线板上的偏压线上。移相器安装在一个包括用来把射频输入和输出信号连接到移相器上的多个微波带状线路184、186、188、190、192、194、196、和198保持器182中。表示在图11中的具体结构为每个移相器提供有其自己的保护壳体。移相器在安装在相控阵天线之前单独地组装和测试。这显著提高通常带有几十个至几千个移相器的天线的生产率。
图12和13是可选择孔径形状的平面图。图12的孔径一般是“I”形的，在每端处有横向矩形部分。图13的孔径是细长的，在每端处有扩口部分。具体孔径形状的选择取决于带宽和加工公差。
为了建造相控阵天线，如图7中所示单独建立移相器。把共面波导管耦合到微波带状线路上，如通过焊接，如图8和9中所示。一个金属壳体放置在移相器上，如图10中所示。如图3中所示建立辐射补片、孔径耦合和馈电线，但没有移相器48。天线板的端线表示为图11的线192、194、196、和198。最后，各个移相器安装在板中，如图11中所示。
移相器包括：一个基片；一个可调谐介电膜，具有在70至600之间的介电常数、20至60％的调谐范围、及在K和Ka频带下在0.008至0.03之间的损失角正切，定位在基片的一个表面上；一个共面波导管，定位在相对基片的可调谐介电膜的一个表面上；一个输入，用来把射频信号耦合到共面波导管上；一个输出，用来从共面波导管接收射频信号；及一个连接，用来把一个控制电压施加到可调谐介电膜上。这里的设备在设计上是独特的，并且在K和Ka频带下呈现低插入损失。
本发明最佳实施例的共面移相器构造在电压调谐钡钛酸盐(BST)基合成膜上。BST合成膜具有优良的低介电损失和合理的可调谐性。这些K和Ka频带共面波导管移相器与基于半导体的移相器相比，提供大功率处理、低插入损失、快速调谐、损失成本、及高抗辐射性能的优点。非常普遍的是，材料的介电损失随频率而增大。常规可调谐材料损失非常大，特别是在K和Ka频带下。由常规可调谐材料制成的共面移相器损失极大，并且对于K和Ka频带下的相控阵天线是无用的。应该注意，本发明的移相器结构适用于任何可调谐材料。然而，只有低损失可调谐材料能实现良好、有用的移相器。对于微波带状线路移相器希望使用低介电常数材料，因为高介电常数材料在用于微波带状线路移相器的这些频率范围下容易产生高EM模式。然而，这样的低介电常数常规材料(＜100)是不可得到的。
在本发明的天线中的移相器的最佳实施例使用合成材料，包括BST和其它材料、及两个或多个相位。这些合成物与常规ST或BST膜相比表现出低得多的介电损失、和合理调谐。这些合成物具有比ST或BST膜低得多的介电常数。低介电常数使得设计和制造移相器容易。这些移相器能在室温(～300°K)下操作。室温操作比在100°K下操作的先有技术移相器容易得多，并且成本低得多。
本发明提供了一种用于跟踪接地终端和空间飞船通信或雷达用途的低成本电气扫描相控阵天线。本发明的最佳实施例包括室温电压调谐共面波导管(CPW)移相器和一个圆偏振微波传输带相控天线。共面移相器构造在电压调谐钡钛酸盐(BST)基合成膜上。BST合成膜具有优良的低介电损失和合理的可调谐性。这些CPW移相器与基于半导体的移相器相比，具有大功率处理、低插入损失、快速调谐、低成本、及高抗辐射性能的优点。相控阵天线包括通过经用于圆偏振的两个正交槽由耦合孔径馈电的方形微波传输带补片。孔径耦合微波传输带天线提供优于传输线或探针馈电补片天线的几个优点，如用于馈电网络的较大空间、对通路需要的消除、输入阻抗的容易控制、优良的圆偏振、及低成本。孔径耦合微波传输带天线对于电压调谐移相器具有一个另外的优点，因为在移相器与辐射补片之间不需要直流阻塞。该优点使得移相器安全和容易偏压。
本发明使用CPW电压调谐移相器，该移相器与微波传输带移相器相比适用于较高频率用途，如以上的Ku频带。CPW移相器与微波传输带移相器相比，也表现出较宽带宽、较低偏压及较简单的结构，孔径耦合技术对于这种电压调谐移相器用途具有一个独特的优点，因为在移相器与辐射元件之间不需要直流隔离。该优点使得天线系统简单、安全及便宜。
尽管在现在是其最佳实施例的方面已经描述了本发明，但对于熟悉本专业的技术人员显然，对最佳实施例能进行各种变更，而不脱离由权利要求书定义的本发明的范围。
