具体实施方式 为了引用和清楚起见, 下文中使用的技术名词、 简写或缩写总结如下: 功分器: 全称功率分配器, 是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。
下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行 清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明一部分实施例, 而 不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有作 出创造性劳动前提下所获得的所有其他实施例 , 都属于本发明保护的范围。
本发明实施例所提供的适应多频段的天线, 需使用宽频辐射器。 为便于 理解, 现先对宽频辐射器作介绍。
宽频辐射器可具有两个端口 (也可称为支持两个端口)或一个端口。 图 1示出了可支持两个端口 (为区别起见, 将这两个端口以第一端口 D1 和第二端口 D2相称) 的宽频辐射器的一种结构: 第一端口 D1所在侧的柱形 馈电装置 N1与第二端口 D2所在侧的外壁 B2相连接,而第二端口 D2所在侧 的柱形馈电装置 N2与第一端口 D1所在侧的外壁 B1相连接。
除了图 1所示的结构, 请参见图 2, 可支持第一端口 D1和第二端口 D2 的宽频辐射器还可为另一结构: U型馈电装置 N插入第一端口 D1所在侧的 外壁 B1内, 以及, 第二端口 D2所在侧的外壁 B2内。
无论是图 1的结构, 还是图 2的结构, 经过一定的设计, 第一端口 D1和 第二端口 D2可分别工作于不同的频段。
具有一个端口(将该端口称为端口 D3 )的宽频辐射器的结构可参见图 3:
端口 D3所在侧的柱形馈电装置 N3与另一振子 Z相连接。 现先对包含具有两个端口的宽频辐射器的天线进行描述。
上述天线可包括至少一个宽频辐射器组, 任一宽频辐射器组可包括至少 两个宽频辐射器和与宽频辐射器一一对应的分频设备。
上述宽频辐射器与分频设备的连接方式有以下几种基本类型:
其一,
请参见图 4a, 分频设备 100包括两个滤波器 2, 每一滤波器 2具有一个 频率接口, 并且, 任一频率接口与其他频率接口均工作于不同的子频段。 而 宽频辐射器 1 的一个端口与其中一个滤波器 2相连, 另一个端口与另一个滤 波器 2相连。
可见, 在图 4a中, 分频设备 100可工作 2个不同的子频段 fl和 (本发 明实施例以 fl , f2来对两个不同的子频段进行区别, 但 fl、 f2不应理解为对 子频段的限制, 应理解为用于区别表示不同的子频段)。 这样, 当宽频辐射器 1与分频设备 100相连时, 宽频辐射器 1也可独立工作于两个子频段 fl和 上。
其二,
请参见图 4b, 分频设备 100包括一个滤波器 2和一个分频器 102, 其中, 滤波器 2具有一个频率接口, 而分频器 102则具有至少两个频率接口, 并且 滤波器 2的频率接口与分频器 102的任一频率接口均工作于不同的子频段上。 宽频辐射器 1的一个端口与滤波器 2相连, 另一个端口与分频器 102相连。
可见, 图 4b中分频设备 100可工作于至少 3个不同的子频段 fl、 、 β (同理, fl、 f2、 β 只用于区别表示不同的子频段)上。 这样, 当宽频辐射 器 1与其相连时, 宽频辐射器 1也可独立工作于至少 3个子频段上。
其三,
请参见图 4c, 分频设备 100包括两个分频器 102, 每一分频器 102具有 至少两个频率接口, 并且, 任一分频器的任一频率接口与其他分频器的任一 频率接口均工作于不同的子频段上。 宽频辐射器 1 的一个端口与其中一个分 频器 102相连, 另一个端口与另一分频器 102相连。
可见,图 4c中的分频设备 100可工作至少 4个不同的子频段 fl-f4(同理,
fl-f4只用于区别表示不同的子频段)。 这样, 当宽频辐射器 1与之相连时, 宽 频辐射器 1也可独立工作于至少 4个子频段上。
需要说明的是, 宽频辐射器 1 可工作的子频段并不只限于分频设备支持 的子频段。 比如, 宽频辐射器 1可支持 fl、 、 β ..... f 等子频段, 但如果宽 频辐射器 1与支持子频段 fl和 G的分频设备相连接,则宽频辐射器 1就工作 于 fl和 β两个相互不干扰的子频段上。 当然, 如果宽频辐射器 1与支持 fl 和 β的分频设备相连接, 则宽频辐射器 1就工作于 fl和 β两个相互不干 4尤 的子频段上, 可依此类推。
另外, 本发明所有实施例中的工作可指接收和发送信号, 也可仅指接收 信号或发送信号。 因此, 宽频辐射器 1 工作于不同的子段频段上, 可理解为 宽频辐射器 1可在不同的子段频段上收发信号, 或者宽频辐射器 1可在不同 的子段频段上接收信号, 或者宽频辐射器 1可在不同的子段频段上发送信号, 本领域技术人员可根据需要进行灵活设计, 在此不作贅述。
除此之外, 请参见图 4d-e, 上述分频设备还可通过各种单设备组合方式, 使宽频辐射器 1独立工作于更多的子频段上。
上述三种方式虽然各有不同, 但总体思路是最终令具有两个端口的宽频 辐射器独立工作于不同的子频段上。 因此, 本发明以下的实施例将主要以方 式一为基础进行描述。
在本发明其他实施例中, 以上所有实施例中的宽频辐射器组还可包括具 有一个连接接口的组内移相器。
图 5和图 6示出了包括组内移相器的一种天线结构, 其具有 3个宽频辐 射器组 (当然在其他实施例中也可为 2个, 4个等等)。 每一宽频辐射器组包 括 2个组内移相器 4, 2个分频设备和 2个宽频辐射器 1。 每一分频设备由支 持子频段 fl的滤波器 2和支持子频段 f2的滤波器 2组成, 宽频辐射器 1的两 个端口分别与这两个滤波器 2相连。
其巾:
参见图 6 (图 6为图 5的局部放大图), 组内移相器 4可与所属宽频辐射 器组中的一个分频设备提供的一个频率接口相连;
或者参见图 7,组内移相器 4还可同时与所属宽频辐射器组中不同分频设 备提供的、 工作于同一子频段的频率接口相连(本发明实施例后续将进行详
细介绍)。
可见, 组内移相器 4的工作子频段与所连接的频率接口工作子频段相同。 由于在图 6和 7中, 宽频辐射器组内各个宽频辐射器 1在水平上呈线性 排列, 因此, 通过改变组内移相器 4 的相位, 可改变组内各个宽频辐射器 1 的相位比例, 实现天线的方位角的改变。
下面将根据图 7详细介绍组内移相器同时与所属宽频辐射器组中不同分 频设备提供的、 工作于同一子频段的频率接口相连的情况。
为方便描述, 将图 7—个宽频辐射器组中的三个宽频辐射器分别称为第 一宽频辐射器 11、 第二宽频辐射器 12和第三宽频辐射器 13。 上述第一宽频 辐射器 11与第一分频设备相连, 第二宽频辐射器 12与第二分频设备相连, 第三宽频辐射器 13与第三分频设备相连。
以 fl子频段为例, 在图 7中, 第一分频设备工作于 fl子频段上的频率接 口和第三分频设备工作于 fl子频段上的频率接口同时与组内移相器 4相连, 经合路后, 通过组内移相器 4 (工作于 fl子频段上)与后续将介绍的功率控 制器 3 (工作于 fl子频段上) 的一个端口相连, 功率控制器 3 (工作于 fl子 频段上) 的另一端口与第二分频设备提供的、 工作于 fl子频段上的频率接口 相连。
同理可推知, 图 7中第一分频设备工作于 f2子频段上的频率接口和第三 分频设备工作于 f2子频段上的频率接口与工作于 子频段上的组内移相器 4 之间的连接关系, 在此不作贅述。
一般情况下, 第一宽频辐射器 11、 第二宽频辐射器 12和第三宽频辐射器 13的相位角分别为 -Α,Ο,Α, 而方位角则是由相位角 -Α和 Α来决定的, 因此, 通过组内移相器 4调节第一宽频辐射器 11和 /或第三宽频辐射器 13的相位角 即可实现对方位角的调节。
需要注意的是, 图 7示出的结构中, 组内移相器 4可同时对第一宽频辐 射器 11和第三宽频辐射器 13的相位角进行调节。 而在本发明其他实施例中, 请参见图 8, 组内移相器 4可仅对某一宽频辐射器(在图 8中为第一宽频辐射 器 11 )进行相位调节, 同样可达到对方位角的调节。
前述提及了功率控制器, 下面将对其进行介绍。
功率控制器可与以上所有实施例中工作于同一子频段的接口相连。 其中,
任一上述工作于同一子频段的接口可为组内移相器提供的连接接口或分频设 备提供的频率接口。
功率控制器具有一个连接接口, 显然, 功率控制器与工作于哪一子频段 的接口相连, 则其连接接口也工作于该子频段上。
仍以图 7-8所示结构为例,功率控制器 3即同时与组内移相器 4提供的连 接接口以及第二分频设备提供的频率接口相连。
当不存在组内移相器时, 请参见图 9: 在一个宽频辐射器组中, 两个分频 设备 100 (每一分频设备 100包括两个滤波器 2 )工作于 fl子频段的频率接口 均与一功率控制器 3相连, 该功率控制器 3的连接接口因而也工作于 fl子频 段上; 同时, 上述两个分频设备 100工作于 子频段的频率接口也与另一个 功率控制器 3相连, 同理, 该功率控制器 3的连接接口工作于 子频段上。
由于图 7-9中, 各个宽频辐射器在水平上呈一线型排列, 因此, 上述功率 控制器 3 可改变水平波瓣宽度。 这是因为在功率一定的情况下, 当每个宽频 辐射器的功率都相同时(或者说各个宽频辐射器均分功率时), 其水平波瓣宽 度最小, 而如果通过功率控制将绝大多部分功率分配于某一个宽频辐射器上 时, 则水平波瓣宽度将达到最宽。 也即, 可通过功率控制器改变每个与之相 连的宽频辐射器的功率大小的方式, 来改变波瓣宽度的大小。
另外, 当天线可独立工作于 N个子频段时, 本领域技术人员可根据实际 需要, 安置 M ( M小于等于 N ) 个功率控制器, 在此不作贅述。
功率控制器的结构有多种形式, 图 10示出了主要由功分器 31、 移相器 32和电桥 33构成的功率控制器。 其中:
电桥 33的第一输出端 1 ( outl )和第二输出端 2 ( out2 )分别与宽频辐射 器直接或间接连接; 功分器 31的第一输出端通过移相器 32与电桥 33的第一 输入端 inl相连,而功分器 31的第二输出端与电桥 33的第二输入端 in2相连。
各部分工作原理如下: 通过移相器 32可改变电桥 inl和 inl的相位比, 从而使 outl与 out2之间信号的功率比发生改变(在极限情况下, 可以使 outl 或 out2的输出能量变为 0 ), 从而实现了功率分配。 这种方式的好处是总的能 量没有发生改变, 只是改变了 outl和 out2的能量比。
在本发明其他实施例中, 请参见图 11和 12, 上述功分器 31和移相器 32 可为一体化设计 (图 11和 12中以 34标识一体化设计的功分器和移相器)。
另外, 在本发明其他实施例中, 当宽频辐射器组的组数不小于 2 时, 以 上所有实施例中的天线还可包括功率分配器和组间移相器中的至少一种。
其中, 功率分配器与所有工作于同一子频段上的功率控制器相连接。 以 图 13所示的具有三组宽频辐射器组的天线结构为例,假设工作于 fl子频段的 功率分配器 5可分配的总功率为 W, 则每一组宽频辐射器组在 fl子频段上可 分得总功率的 1/3 , 也即 1/3W, 进而, 每个宽频辐射器组内工作于 fl子频段 上的功率控制器 3可对上述 1/3W再进行分配。 工作于 G子频段上的功率分 配器 5与其他各部件的配合与之相类似, 在此不作贅述。
至于组间移相器, 则与所有工作于同一子频段的接口相连。 比如, 工作 于 fl子频段的组间移相器与所有工作于 fl子频段的接口相连。
任一上述工作于同一子频段的接口可为组内移相器提供的连接接口或分 频设备提供的频率接口或功率控制器提供的连接接口。
参见图 14, 工作于 fl子频段的组间移相器 6即与所有工作于 fl子频段 的功率控制器 3的连接接口相连。 对于图 14所示的天线结构而言, 组间移相 器 6可通过移相来实现天线下倾。
当然, 如果各个宽频辐射器组在水平上呈一线型排列, 而每一宽频辐射 器组内的各个宽频辐射器在垂直上呈线型排列的话, 则上述组间移相器可实 现方位角改变, 相应的, 组内移相器可实现天线下倾。
此外, 功率分配器 5和组间移相器 6还可一并使用, 在此不作贅述。 在由包括三个宽频辐射器的宽频辐射器组所构成的天线中, 各宽频辐射 器与功率控制器、 功率分配器和组间移相器的相互关系可参照前述由包括两 个宽频辐射器的宽频辐射器组所构成的天线的相关描述, 在此不作贅述。 以上所有实施例均是以具有两个端口的宽频辐射器为基础进行介绍的, 下面将以具有一个端口的宽频辐射器为基础, 对本发明实施例欲保护的天线 进行介绍。
以具有一个端口的宽频辐射器为基础构成的天线, 包括至少一个宽频辐 射器组。 每一宽频辐射器组包括至少两个宽频辐射器和与上述宽频辐射器一 一对应的分频设备。 其中, 分频设备可包括至少一个分频器, 宽频辐射器的 端口与上述分频器相连, 而上述分频器又具有至少两个工作于不同子频段的
频率接口。
由于分频器具有至少两个工作于不同子频段的频率接口, 因此, 当宽频 辐射器与其相连时, 宽频辐射器也可独立工作于至少两个独立的子频段上。 也即, 分频器在分频的同时, 可令宽频辐射器由一个端口变为两个端口或两 个以上端口。
图 15和 16 (图 16为图 15的局部放大图)即示出了主要由具有一个端口 的宽频辐射器构成的天线的一种结构, 其包括: 3个宽频辐射器组, 任一宽频 辐射器组包括 2个分频器 102 (分频设备)和 2个宽频辐射器 101 (为与前述 具有两个端口的宽频辐射器相区别, 本实施例以宽频辐射器 101 表示具有一 个端口的宽频辐射器, 当然, 与前述相类似, 每一宽频辐射器组中所包含的 宽频辐射器 101的数量也可以为 3个或其他)。 分频器 102又具有两个频率接 口, 分别工作于子频段 fl和 f2。
需要说明的, 宽频辐射器 101可支持的子频段并不只限于上述 fl和 , 比如其可支持 fl、 、 β ..... f 子频段, 但如果分频器 102只工作于子频段 fl 和 f2上, 则宽频辐射器 101也随之工作于 fl和 G两个相互不干扰的子频段 上。 而如果分频器 102可工作于 fl和 β这两个子频段上, 则宽频辐射器 101 就可以工作于 fl和 β两个相互不干扰的子频段上, 可依次进行类推。
同时需要注意的是, 图 15和 16中的分频设备仅包括一个分频器, 但与 前述相类似,分频设备可通过器件组合来提供 3个, 4个乃至更多个频率接口 , 并且每一频率接口的的工作子频段都可不同于其他频率接口, 在此不作贅述。
在本发明其他实施例中, 以上所有实施例中的宽频辐射器组还可包括具 有一个连接接口的组内移相器。 由前述可知, 通过改变组内移相器的相位, 可实现天线的方位角的改变或天线下倾。
仍请参见图 16, 上述组内移相器 4可与所属宽频辐射器组中的一个分频 设备提供的一个频率接口相连;
或者参见图 17, 组内移相器 4可同时与所属宽频辐射器组内不同分频设 备提供的、 工作于同一子频段的频率接口相连(本发明实施例后续将进行详 细介绍)。
下面将根据图 17详细介绍组内移相器 4同时与所属宽频辐射器组中不同 分频设备提供的、 工作于同一子频段的频率接口相连的情况。
为方便描述, 将图 17中每一宽频辐射器组所包括的三个宽频辐射器分别 称为第四辐射器 ill ,第五辐射器 112和第六辐射器 113 ,上述第四辐射器 111 与第四分频设备 121相连, 第五辐射器 112与第五分频设备 122相连, 第六 辐射器 113与第六分频设备 123相连。
以 fl子频段为例,第四分频设备 121工作于 fl子频段的频率接口和第六 分频设备 123工作于 fl子频段的频率接口同时与组内移相器 4相连, 经合路 后通过组内移相器 4 (工作于 fl子频段上) 与功率控制器 3 (工作于 fl子频 段上) 的一个端口相连, 功率控制器 3 (工作于 fl子频段上) 的另一端口与 第五分频设备 122提供的、 工作于 fl子频段上的频率接口相连。
由于组内移相器 4与各部件的连接关系及其可实现的功能, 与前述以具 有两个端口的宽频辐射器为基础的天线相类似, 在此不作贅述。
在本发明其他实施例中, 当宽频辐射器组的组数不小于 2 时, 以上所有 实施例中的天线还可包括功率分配器和组间移相器中的至少一种。
而上述功率分配器与各部件的连接关系及其可实现的功能, 与前述功率 分配器 5相类似, 上述组间移相器与各部件的连接关系及其可实现的功能, 与前述组间移相器 6相类似, 在此均不作贅述。 在本发明其他实施例中, 还可使用双极化相互正交的宽频辐射器 (参见 图 18 ) 来组成天线。 双极化相互正交的宽频辐射器可视为由两个宽频辐射器 构成。 其中, 双极化相互正交辐射器的一个极化可支持一个端口, 也可支持 两个端口 (支持两个端口的请参见图 19, 在图 19中, 使用 D1端口和 D2端 口区别极化 1不同的端口)。
也即, 一个双极化相互正交的宽频辐射器, 可视为由两个上述宽频辐射 器 1 , 或者由两个上述宽频辐射器 101 , 或者由一个上述宽频辐射器 1和一个 上述宽频辐射器 101构成。 因此, 适用于上述宽频辐射器 101和上述宽频辐 射器 1 的天线结构, 同样适用于由双极化相互正交的宽频辐射器构成的天线 结构。 在此不作贅述。 本说明书中各个实施例采用递进的方式描述, 每个实施例重点说明的都 是与其他实施例的不同之处, 各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明, 使本领域专业技术人员能够实现或使用 本发明。 对这些实施例的多种修改对本领域的专业技术人员来说将是显而易 见的, 本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下, 在其它实施例中实现。 因此, 本发明将不会被限制于本文所示的这些实施例, 而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
