Description

天线及电子设备
本申请要求于2021年11月1日提交国家知识产权局、申请号为202111282691.5、申请名称为“天线及电子设备”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。
技术领域
本申请实施例涉及天线技术领域，尤其涉及天线及电子设备。
背景技术
随着通信技术的发展，电子设备上通常设置有天线，用于与其他电子设备之间进行通信连接。例如，在电视上设置天线，电视通过天线与遥控器连接，以使遥控器能够控制电视。
电子设备上通常还集成其他功能器件。继续以电视为例，电视上通常有音响、支脚架等，这些器件需要安装在指定的位置。因此天线通常会被设置在电视的两边相交的位置。当天线设置在电视的两边相交的位置，会导致天线的方向性高，电视的屏前覆盖性较差。
基于此，有必要提供一种方向性低的天线，以提高信号在电视屏前的覆盖性。
发明内容
本申请实施例提供天线及电子设备，能够提高信号在电视屏前的覆盖性。
第一方面，提供了一种天线，天线设置电子设备中，电子设备包括金属背板，天线包括第一谐振腔体和馈电源；第一谐振腔体包括第一缝隙和第二缝隙，第一缝隙设置在第一谐振腔体中的第一平面，第一平面为第一谐振腔体上长边所在的平面；第二缝隙设置在第一谐振腔体中与第一平面相邻的第二平面，第一平面、第二平面与金属背板所在的平面垂直；馈电源设置在第一谐振腔体内，用于对天线进行馈电。
本申请的实施例中提供的天线设置在电子设备中，电子设备包括金属背板，天线包括第一谐振腔体和馈电源，第一谐振腔体包括第一缝隙和第二缝隙，第一缝隙设置在第一谐振腔体中的第一平面，第一平面为第一谐振腔体上长边所在的平面；第二缝隙设置在第一谐振腔体中与第一平面相邻的第二平面，第一平面、第二平面与金属背板所在的平面垂直；馈电源设置在第一谐振腔体内，用于对天线进行馈电，采用包括第一谐振腔体的天线，并通过第一谐振腔体上的第一缝隙和第二缝隙辐射信号，使得采用本申请实施例中的天线可以提高缝隙天线辐射方向的维度，从而降低了天线的方向性，进而使得信号可以覆盖到电子设备屏前的大部分区域，提高了电子设备屏前的信号覆盖度。
在一个实施例中，上述第一谐振腔体为L型谐振腔体。
本申请的实施例中，采用L型谐振腔体作为第一谐振腔体，经过仿真及测试，采 用L型谐振腔体作为第一谐振腔体的天线屏前覆盖度最优。
在一个实施例中，上述L型谐振腔体设置在电子设备的第一边和第二边相交的位置，第一平面与第一边之间的距离最小，第二平面与第二边之间的距离最小。
应理解，第一边和第二边为电子设备上的外边框，L型谐振腔体上各个平面与第一边之间的距离是指各个平面与电子设备在第一边方向上的外边框之间的距离，L型谐振腔体上各个平面与第二边之间的距离是指各个平面与电子设备在第二边方向上的外边框之间的距离。第一平面是与第一边之间的距离最小的平面，则第一平面是第一谐振腔体沿第一边朝向外侧平面。第二平面是与第二边之间的距离最小的平面，则第二平面是第一谐振腔体上沿第二边朝向外侧的平面。也即是说，设置在第一平面上的第一缝隙超朝向电子设备外侧，设置在第二平面上的第二缝隙朝向电子设备的外侧。
在一个实施例中，上述第一缝隙的尺寸和第二缝隙的尺寸与天线的工作频段关联。
应理解，由于缝隙的宽度并不影响天线的边界条件，因此，天线的工作频段只与第一缝隙的长度和第二缝隙的长度强关联。
在一个实施例中，上述第一缝隙的长度与第二缝隙的长度相同。
本申请的实施例中，当第一缝隙的长度与第二缝隙的长度相同时，相当于天线在不同朝向的辐射口的长度相同。天线通过长度相同的第一缝隙和第二缝隙辐射信号，使得信号在电子设备的屏前各个方向能均匀的覆盖，相当于提高了电子设备的屏前覆盖度。
在一个实施例中，上述天线还包括填充介质，填充介质设置在馈电源和第一谐振腔体之间，用于固定馈电源。
本申请的实施例中，天线还包括填充介质，填充介质设置在馈电源和第一谐振腔体之间，用于固定馈电源。采用填充介质固定馈电源，可以利用天线中已有的组件固定馈电源，避免了单独使用独立的器件来固定馈电源，避免了材料的浪费，降低了天线的成本。
在一个实施例中，上述第一谐振腔体还包括第三缝隙，第三缝隙设置在第一谐振腔体中的第三平面，第三平面与第一平面或者第二平面相邻，且第三平面与金属背板所在的平面垂直。
本申请的实施例中提供了的天线设置在电子设备中，电子设备包括金属背板，天线包括第一谐振腔体和馈电源，第一谐振腔体包括第一缝隙、第二缝隙和第三缝隙，第一缝隙设置在第一谐振腔体中的第一平面，第二缝隙设置在第一谐振腔体中与第一平面相邻的第二平面，第三缝隙设置在第一谐振腔体的第三平面，第一平面、第二平面和第三平面与金属背板所在的平面垂直，第三平面与第一平面或者第二平面相邻，馈电源设置在第一谐振腔体内。通过采用包括第一谐振腔体的天线，并通过第一谐振腔体上的第一缝隙、第二缝隙和第三缝隙辐射信号，使得采用本申请实施例中的天线可以提高缝隙天线辐射方向的维度，从而降低了天线的方向性，进而使得信号可以覆盖到电子设备屏前的大部分区域，提高了电子设备屏前的信号覆盖度。
在一个实施例中，上述第一缝隙的尺寸、第二缝隙的尺寸和第三缝隙的尺寸与天线的工作频段关联。
应理解，由于缝隙的宽度并不影响天线的边界条件，因此，天线的工作频段只与 第一缝隙的长度、第二缝隙的长度和第三缝隙的长度强关联。
在一个实施例中，上述天线的工作频段是根据第一公式确定的，第一公式包括：
Figure PCTCN2022115531-appb-000001
其中，μ表示填充介质的磁导率，ε表示填充介质的电容率，m表示等效腔体在X轴方向上半波长的数量，等效腔体为与第一谐振腔体等效的矩形谐振腔体，a表示等效腔体在X轴方向的长度，n表示等效腔体在Y轴方向上半波长的数量，b表示等效腔体在Y轴方向的长度，p表示等效腔体在Z轴方向上半波长的数量，l表示等效腔体在Z轴上的长度，等效腔体在Z轴上的长度是根据第一谐振腔体上的缝隙尺寸确定的。
本申请的实施例中，天线的工作频段和第一谐振腔体的缝隙尺寸相关，使得在工作频段确定的情况下，可以根据第一公式确定与天线的工作频段更加匹配的缝隙尺寸，进而使得天线在其工作频段上的性能良好，进而提高了电子设备采用该天线的屏前覆盖度。
在一个实施例中，上述馈电源设置在第一谐振腔体中基模电场强度最大处。
应理解，由于第一谐振腔体可以是L型谐振腔体，上述基模电场强度最大处可以是等效腔体的基模电场强度最大处，第一谐振腔体中基模电场强度最大处具体位置可以通过仿真确定。
本申请的实施例中，将馈电源设置在第一谐振腔体的基模电场强度最大处，可以使工作在第一谐振腔体基模频段的天线的阻抗匹配更好，进而提高了天线的辐射效率带宽。
在一个实施例中，上述馈电源通过螺钉固定在金属背板上。
在本申请的实施例中，馈电源可以通过螺钉固定在金属背板上，使得固定馈电源的方式更加简便。
第二方面，提供了一种电子设备，该电子设备包括如上述第一方面所述的天线。
在一个实施例中，上述电子设备包括显示屏，显示屏的尺寸大于预设阈值。
在一个实施例中，上述电子设备为智慧大屏。
上述电子设备的实现方式及有益效果与第一方面所述的天线类似，此处不再赘述。

具体实施方式
下面将结合附图对本申请实施例中的技术方案进行清楚、详尽地描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；文本中的“和/或”仅仅是一种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这三种情况，另外，在本申请实施例的描述中，“多个”是指两个或多于两个。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为暗示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征，在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
目前，电子设备上通常设置有天线，用于与其他电子设备之间进行通信连接。示例性的，如图1所示，电视10通过天线10A与其他电子设备20通信连接。其中，一些其他电子设备20可以是蓝牙音箱20A、路由器20B、蓝牙耳机20C或者遥控器20D，本申请实施例对此不作限制。
下面以电子设备是电视，其他电子设备是遥控器为例进行说明。如图2所示，在电视上设置天线10A，电视通过天线10A与遥控器20连接，以使遥控器20能够控制电视。通常电视上还集成有其他的器件，如图2中所示的音响10B、支脚架10C和逻辑板10D(T－CON)。这些器件必须设置在电视10的限定区域，才能更好地实现对应的功能。例如，支脚架10C只有设置在电视的底边，才能支撑电视。由于电视中的其他器件占用电视上的区域，使得天线10A可以设置的区域通常被限定在电视的两边相交的位置。现有技术中，通常采用的微带天线(Patch Antenna，PIFA)作为与其他电子设备之间进行通信的天线。当PIFA设置在电视的两边相交的位置，PIFA的方向图如图3中的(a)所示，方向性较高，PIFA在垂直方向和水平方向的电场强度分布图如图3中的(b)所示，电场强度变化较大，且屏前场强衰减相对屏后衰减更快。也即是说，采用PIFA作为电视的天线10A，使得电视的屏前信号覆盖性差，导致电视与屏前的其他电子设备之间的通信较差。
进一步地，电视上通常还设置有金属背板10E，该金属背板10E的尺寸通常较大。当电视上的天线10A是PIFA时，PIFA更容易受到金属背板10E感应的地板电流的影 响，导致方向图上的零点增多，从而导致水平面方向图波纹加深，进一步地增大了天线的方向性，使得电视的屏前信号覆盖性进一步地恶化。
有鉴于此，本申请提供了一种天线，该天线设置在电视两边相交的位置时，可以降低天线的方向性，提高电视的屏前信号覆盖性。本申请的实施例中的天线包括第一谐振腔体、馈电源和填充介质，其中，第一谐振腔体包括第一缝隙和第二缝隙，第一缝隙设置在第一谐振腔体中与第一位置相邻的第一平面，第二缝隙设置在第一谐振腔体中与第一位置相邻的第二平面，第一平面与第二平面与金属背板所在的平面垂直，其中，第一位置是指电子设备的两边相交的位置，通过第一谐振腔体上的第一缝隙和第二缝隙辐射信号，能够有效地降低天线的方向性，提高电子设备的屏前信号覆盖度。
下面将结合图4至图15所示实施例来详细说明。
图4为本申请一个实施例中天线的结构示意图，如图4所示，本申请实施例提供了一种天线10A，天线10A设置在电子设备10中，电子设备10包括金属背板10E，天线10A包括第一谐振腔体11A和馈电源12A，第一谐振腔体11A包括第一缝隙11A1和第二缝隙11A2，第一缝隙11A1设置在第一谐振腔体11A中的第一平面11A3，第一平面11A3为第一谐振腔体11A上长边所在的平面，第二缝隙11A2设置在第一谐振腔体11A中与第一平面11A3相邻的第二平面11A4，第一平面11A3、第二平面11A4与金属背板10E所在的平面垂直，馈电源12A设置在第一谐振腔体11A内，用于与对天线进行馈电。
应理解，第一谐振腔体11A可以设置在电子设备的任意位置。在一种可能的情况下，第一谐振腔体11A可以设置电子设备10任一个两边相交的位置，也即是电子设备10上四个角所在的位置。可选地，第一谐振腔体11A可以设置在电子设备10的第一边10F和第二边10G相交的位置。示例性的，如图4所示，第一谐振腔体11A是电子设备10左下角横边和竖边相交的位置。
继续如图4，第一谐振腔体11A包括第一缝隙11A1和第二缝隙11A2，第一缝隙11A1设置在第一谐振腔体11A中的第一平面11A3，第一平面11A3为第一谐振腔体11A上长边所在的平面，第二缝隙11A2设置在第一谐振腔体11A中与第一平面11A3相邻的第二平面11A4，第一平面11A3与第二平面11A4与金属背板10E所在的平面垂直。
在一种可能的情况下，可选地，第一平面11A3与电子设备的第一边10F之间的距离最小，第二平面11A4与电子设备10的第二边10G之间的距离最小。
应理解，第一边10F和第二边10G为电子设备10上的外边框，第一谐振腔体11A上各个平面与第一边10F之间的距离是指各个平面与电子设备10在第一边10F方向上的外边框之间的距离，第一谐振腔体11A上各个平面与第二边10G之间的距离是指各个平面与电子设备10在第二边10G方向上的外边框之间的距离。第一平面11A3是与第一边10F之间的距离最小的平面，则第一平面11A3是第一谐振腔体11A沿第一边10F朝向外侧的平面。第二平面11A4是与第二边10G之间的距离最小的平面，则第二平面11A4是第一谐振腔体11A上沿第二边10G朝向外侧的平面。也即是说，设置在第一平面11A3上的第一缝隙11A1超朝向电子设备10外侧，设置在第二平面11A4上的第二缝隙11A2朝向电子设备10的外侧。
示例性的，如图4所示，第一谐振腔体11A上与金属背板10E垂直的平面中，朝向电子设备的外侧的平面有两个，分别为第一平面11A3和第二平面11A4。
应理解，第一缝隙11A1的长度可以与第一平面11A3的长度相同，也可以略小于第一平面11A3的长度，本申请实施例对此不作限制。第二缝隙11A2的长度可以与第二平面11A4的长度相同，也可以略小于第二平面11A4的长度，本申请实施例对此不作限制。
可选地，第一谐振腔体11A为L型谐振腔体。
如图5所示，第一谐振腔体11A可以是通过第一钢片1A和第二钢片1B进行弯折得到的。其中，L1为第一缝隙11A1的长度，L2为第二缝隙11A2的长度，a表示第一谐振腔体11A的宽度，b表示第一谐振腔体11A的高度，w 1表示第一缝隙的宽度，w 2表示第二缝隙的宽度。需要说明的是，w 1可以与w 2相等。经过仿真及测试，采用L型谐振腔体作为第一谐振腔体的天线屏前覆盖度最优。
可选地，第一缝隙11A1的尺寸和第二缝隙11A2的尺寸与天线10A的工作频段关联。
由于缝隙的宽度并不影响天线的边界条件，因此，天线10A的工作频段只与第一缝隙11A1的长度和第二缝隙11A2的长度强关联。
示例性的，天线10A的工作频段可以是根据以下公式确定的：
Figure PCTCN2022115531-appb-000002
其中，μ表示填充介质13A的磁导率，ε表示填充介质13A的电容率，m表示等效腔体在X轴方向上半波长的数量，等效腔体为与第一谐振腔体11A等效的矩形谐振腔体，a表示等效腔体在X轴方向的长度，n表示等效腔体在Y轴方向上半波长的数量，b表示等效腔体在Y轴方向的长度，p表示等效腔体在Z轴方向上半波长的数量，l表示等效腔体在Z轴上的长度，等效腔体在Z轴上的长度是根据第一谐振腔体11A上的第一缝隙11A1的长度和第二缝隙11A2的长度确定的。
需要说明的是，本申请实施例提供的天线10A的工作频段通常是第一谐振腔体11A的基模频段，即天线10A工作第一谐振腔体11A在TE 0.501模式。当第一谐振腔体11A工作在TE 0.501模式时，矩形谐振腔体的电场场强分布图如图6所示，此时沿着x方向，将矩形谐振腔体剖成两半，取其一半，即可得到第一谐振腔体11A的等效电场分布。延X轴的正向，电场场强从弱变强，再从强变弱，相当于电信号在X轴的正向行进了如图7所示的1个半波长。类似的，延Z轴的正向，电场场强无明显变化，说明电信号在Z轴方向未行进，相当于0个半波长。延Y轴的正向电场场强从强变弱，相当于电信号在Y轴的正向行进了0.5个半波长。也即是说，上述公式中的m＝1，n＝0.5，p＝0。可以将第一谐振腔体11A的尺寸作为仿真模型的输入，计算得到等效腔体在Y轴方向的长度a及等效腔体在X轴上的长度l。其中，第一谐振腔体11A的尺寸中包括第一缝隙11A1的长度和第二缝隙11A2的长度。
本申请天线的工作频段和第一谐振腔体的缝隙尺寸相关，使得在工作频段确定的情况下，可以根据第一公式确定与天线的工作频段更加匹配的缝隙尺寸，进而使得天线在其工作频段上的性能良好，进而提高了电子设备采用该天线的屏前覆盖度。
可选地，馈电源12A设置在第一谐振腔体11A中基模电场强度最大处。
示例性的，可以通过对第一谐振腔体11A进行仿真，确定第一谐振腔体11A的基模电场强度最大的点，然后将馈电源12A设置在该点。
本申请的实施例中，将馈电源设置在第一谐振腔体的基模电场强度最大处，可以使工作在第一谐振腔体基模频段的天线的阻抗匹配更好，进而提高了天线的辐射效率带宽。
可选地，该天线10A还包括填充介质13A，填充介质13A设置在馈电源12A和第一谐振腔体11A之间，用于固定馈电源12A。
应理解，天线通常均采用填充介质，用于调整天线的阻抗，以使天线的阻抗为最佳阻抗。
本申请的实施例中，采用填充介质固定馈电源，可以利用天线中已有的组件固定馈电源，避免了单独使用独立的器件来固定馈电源，避免了材料的浪费，降低了天线的成本。
可选地，馈电源12A通过螺钉固定在金属背板10E上。
示例性的，馈电源12A可以设置有螺钉的安装法兰，金属背板10E上可以设置有固定螺钉的螺纹孔。可以将螺钉通过上述安装法兰插入螺纹孔中，将馈电源12A固定在金属背板10E上。
在本申请的实施例中，馈电源可以通过螺钉固定在金属背板上，使得馈电源的固定方式更加简便。
下面将通过图8至图12来详细描述如何通过图4所示的天线提高电子设备的屏前信号覆盖度的原理。
缝隙天线的远区辐射场仅由缝隙处的场分布确定，因此，在电子设备上设置的缝隙天线不容易受到金属背板感应的地板电流的影响。
示例性的，如图8所示，当电子设备上设置有一个缝隙辐射口朝左侧的缝隙天线时，等效为沿着轴方向的磁流，因此该缝隙天线具有垂直于轴向方向的全向方向图，同时具有低剖面垂直极化的特性。由于边缘效应，仍有相当强度的电力线绕过棱边，通过感应电势差激发背面的电场，实现背面的场覆盖。因此图8所示的缝隙天线的方向图如图9中的(a)所示，水平面方向性参数如图9中的(b)所示，电场强度分布图如图9中的(c)所示。可以看出，采用缝隙辐射口朝左侧的缝隙天线时，电子设备屏前上方区域和下方区域的信号较差。如图10所示，当电子设备上设置一个缝隙辐射口朝下的缝隙天线时，其方向图如图11中的(a)所示，水平面方向性参数如图11的(b)所示，电场强度分布图如图9中的(c)所示。可以看出，采用缝隙辐射口朝下方的缝隙天线时，电子设备屏前左侧区域和右侧区域的信号较差。
采用如图4所示的天线10A，由于天线10A上有两个朝向的缝隙辐射口(即第一缝隙11A1和第二缝隙11A2)，相当于增加了缝隙天线的辐射口朝向的维度，可以降低天线10A的方向性。示例性的，天线10A的方向图如图12中的(a)所示，水平面方向性参数如图12中的(b)所示，电场强度分布图如图12中的(c)所示。可以看出，采用天线10A上，电子设备屏前的信号覆盖度好。
可选地，第一缝隙11A1的长度与第二缝隙11A2的长度相同。
当第一缝隙11A1的长度与第二缝隙11A2的长度相同时，相当于天线10A在不 同朝向的辐射口的长度相同。天线10A通过长度相同的第一缝隙11A1和第二缝隙11A2辐射信号，使得信号在电子设备的屏前各个方向能均匀的覆盖，相当于提高了电子设备的屏前覆盖度。
本申请的实施例中提供的天线设置在电子设备中，电子设备包括金属背板，天线包括第一谐振腔体和馈电源，第一谐振腔体包括第一缝隙和第二缝隙，第一缝隙设置在第一谐振腔体中的第一平面，第一平面为第一谐振腔体上长边所在的平面；第二缝隙设置在第一谐振腔体中与第一平面相邻的第二平面，第一平面、第二平面与金属背板所在的平面垂直；馈电源设置在第一谐振腔体内，用于对天线进行馈电，采用包括第一谐振腔体的天线，并通过第一谐振腔体上的第一缝隙和第二缝隙辐射信号，使得采用本申请实施例中的天线可以提高缝隙天线辐射方向的维度，从而降低了天线的方向性，进而使得信号可以覆盖到电子设备屏前的大部分区域，提高了电子设备屏前的信号覆盖度。
图13为本申请另一个实施例中天线的结构示意图，如图13所示，提供了一种天线10A，天线10A设置在电子设备10的第一区域11，第一区域11是指电子设备10中第一位置111的所在区域，第一位置111是指电子设备10的两边相交的位置，电子设备10包括金属背板10E，天线10A包括第一谐振腔体11A、馈电源12A和填充介质13A，第一谐振腔体包括第一缝隙11A1、第二缝隙11A2和第三缝隙11A5，第一缝隙11A1设置在第一谐振腔体11A中与第一位置111相邻的第一平面11A3，第二缝隙11A2设置在第一谐振腔体11A中与第一位置111相邻的第二平面11A4，第三缝隙11A5设置在第三平面11A6上，第一平面11A3、第二平面11A4和第三平面11A6与金属背板10E所在的平面垂直，第三平面11A6与第一平面11A3或第二平面11A4相邻，馈电源12A设置在第一谐振腔体11A内，用于与电子设备10中的信号传输装置(图中未示出)连接，填充介质13A设置在馈电源12A和第一谐振腔体11A之间，用于固定馈电源12A。
应理解，第三缝隙11A5的长度可以与第三平面11A6的长度相同，也可以略小于第三平面11A6的长度，本申请实施例对此不做限制。第三平面11A6可以与第一平面11A3相邻，或者，第三平面11A6可以与第二平面11A4相邻，本申请实施例对此不作限制。
在一个示例中，第一谐振腔体11A为L型的谐振腔体时，第三平面11A6可以设置在L型谐振腔体的上方，如图14中的(a)所示，第三平面11A6也可以设置在L型谐振腔体的侧边，如图14中的(b)所示，本申请实施例对此不作限制。
示例性的，第一谐振腔体11A可以通过如图15所示的钢片弯折得到的。如图15所示，通过第三钢片1C和第四钢片1D进行弯折得到的。其中，L1为第一缝隙11A1的长度，L2为第二缝隙11A2的长度，L3为第三缝隙11A5的长度，a表示第一谐振腔体11A的宽度，b表示第一谐振腔体11A的高度，w 1表示第一缝隙的宽度，w 2表示第二缝隙的宽度，w 3表示第三缝隙的宽度。需要说明的是，w 1、w 2与w 3可以相等。
在一个示例中，第一谐振腔体11A可以为矩形谐振腔体，第一平面11A3、第二平面11A4和第三平面11A6可以如图16所示。
当第一谐振腔体11A上包括第一缝隙11A1、第二缝隙11A2和第三缝隙11A5时， 天线10A的工作频段与第一缝隙11A1的尺寸、第二缝隙11A2的尺寸和第三缝隙11A5的尺寸关联。其中，由于缝隙的宽度不影响天线10A的边界条件，因此，天线10A的工作频段与第一缝隙11A1的长度、第二缝隙11A2的长度和第三缝隙11A5的长度关联。
示例性的，天线10A的工作频段是根据以下公式确定，包括：
Figure PCTCN2022115531-appb-000003
其中，μ表示填充介质13A的磁导率，ε表示填充介质13A的电容率，m表示等效腔体在X轴方向上半波长的数量，等效腔体为与第一谐振腔体11A等效的矩形谐振腔体，a表示等效腔体在X轴方向的长度，n表示等效腔体在Y轴方向上半波长的数量，b表示等效腔体在Y轴方向的长度，p表示等效腔体在Z轴方向上半波长的数量，l表示等效腔体在Z轴上的长度，等效腔体在Z轴上的长度是根据第一谐振腔体11A上的第一缝隙11A1的长度、第二缝隙11A2的长度和第三缝隙11A5的长度确定的。
在确定第一谐振腔体11A的等效腔体时，可以将第一谐振腔体11A的尺寸作为仿真模型的输入，计算得到等效腔体在X轴方向的长度a及等效腔体在Z轴上的长度l。其中，第一谐振腔体11A的尺寸中包括第一缝隙11A1的长度、第二缝隙11A2的长度和第三缝隙11A5的长度。
