更新说明

一、新天线(将Antenna Magus中的设备总数增加到340)是：

针馈四边间隙耦合微带天线(FEGCOMA)

印刷自匹配正常模式螺旋天线

二、针馈四边间隙耦合微带天线(FEGCOMA)

尽管微带天线由于其简单性和与电路板技术的兼容性而在微波频率范围内非常流行，但它们有限的带宽通常限制了它们的有用性。

已经提出了各种方法来克服这种限制 - 包括使用间隙或直接耦合的寄生贴片。在FEGCOMA中，这些寄生贴片放置在驱动贴片元件的所有四个边缘旁边。引入具有略微不同谐振长度的寄生贴片产生进一步的谐振，从而改善标准贴片的带宽和增益。在这种情况下，该结构被优化以获得具有接近最佳间隔的零的明确定义的可设计带宽。可以预期典型增益值为10 dBi，可设计的分数阻抗带宽在12%和30%之间。

正常模式螺旋天线(NMHA)通常用于手持无线电收发器和移动通信应用。印刷的自匹配NMHA自然匹配50Ω，因此避免了在共振时匹配类似结构的典型设计挑战。

三、印刷自匹配正常模式螺旋天线

它具有与其他NMHAs类似的特性，即：它是紧凑的(总高度通常为0.14λ)，它是垂直极化和全向的，带宽约为3%。

螺旋结构由两个(内部和外部)宽度相等的金属螺旋条组成，它们之间具有中心介电部分。

我们为查找模式和设计模式引入了无规范状态，这在不需要特定规范的工作流程中很有用。

四、没有规范工作流程

从“起始页”选择“查找天线”时，“查找模式”将在“规范已禁用”状态下启动。在此模式下添加到集合的原型将没有与规范的初始链接，也没有参考设计。

可以使用功能区上提供的按钮根据需要启用/禁用规范工作流程。可以在“查找模式”和每个原型中单独更改所选状态。

五、设计范围外推

在某些情况下，Antenna Magus施加的设计范围限制可能过于严格。引入了设计范围外推(DRE)以扩展所有器件的支持设计范围。启用DRE时，设计目标的滑块和范围工具提示表示扩展范围。DRE默认处于活动状态，可以通过导航到“起始页”>“设置”>“设计和估计”来禁用/启用。目前，对于任何给定的设计，只有一个目标可能在扩展范围内。

DRE采用双层设计方法，使用具有超出验证范围的Objective值的直接设计，然后基于验证范围内的设计进行第二次外推阶段，以找到最佳可能的设计预测。虽然DRE方法几乎可以为所有情况生成良好的一阶设计，但有时DRE可能会建议不合标准的设计。如果DRE未能找到有效的设计，则会显示一条消息。

六、近场源出口

现在，对于大多数设计和调整，可以计算和输出每个3D远场的等效近场数据。近场数据无法在Antenna Magus中可视化，但可以以与CST Studio Suite场源兼容的格式导出。由于近场计算可能会降低性能估算，因此默认情况下禁用近场计算，必须在“设置”中启用。在此设置关闭时，估计的设计和调整数据不可用。

七、数组运算符

阵列合成工具中添加了各种阵列操作符。这些运算符可以将基本布局(在Antenna Magus中创建或使用* .tsv数组布局格式导入)转换为更高级的布局。可以以特定顺序顺序地应用多个阵列运算符以实现期望的布局。

运营商包括：

基本运算符，如旋转，平移和缩放。

保形操作符，允许将布局覆盖或投影到几何表面(如抛物面或球体)上。

离散化，可以使用来离散的相位和幅度的运营商。

执行数组操作的特殊操作符，例如循环分段操作符，它尝试以分段圆形模式复制和排列多个基本布局。

八、路德维希三世轴旋转

Ludwig III可视化提供了一种在典型的实验室测量设置中比较模拟远场辐射模式与测量模式的方法。Antenna Magus提供的共极和交叉极化选项(根据论文中描述的第三个坐标系变换：Arthur C. Ludwig，“交叉极化的定义”，IEEE天线和传播交易，1973年1月)假设传播在Z方向和沿Y轴取向的E场。

由于并非Antenna Magus中的所有天线都根据此定义定向，因此并非总是可以在预期的坐标方向上绘制共极和交叉极化。为了解决这个问题，Antenna Magus增加了一个额外的设置，允许用户定义相对于全局坐标系用于Ludwig III可视化的坐标系的方向。

九、导出宏

现在可以导出设计变量并以宏/脚本格式保存。这可以从导出模式或设计模式中进行。目前支持两种格式：

VBA宏(* .mcr - 由CST Studio Suite支持)

LUA脚本(* .lua - 由ALTAIR FEKO 14.0及以后版本支持)

运行宏/脚本(如支持的工具文档中所述)将更新根据项目中的Antenna Magus模板命名的所有变量的值，而不会影响任何其他几何或导出后修改。在导出后形成Antenna Magus导出的模型或构成复杂装配的一部分时，这尤其有用。

“设置菜单”已重新组织，以适应新功能的其他设置。这些将在下面详细说明。设置菜单和其他设置

十、设计与评估

设计范围外推和近场源导出的新设置已添加到“设计和估算”选项卡中。两者都在本期简报的各个部分中有更详细的描述。

Updated instruction

A. new Antenna (increasing the total number of devices in the Antenna Magus to 340) is:

FEGCOMA

Printed self-matching normal mode spiral antenna

2. FEGCOMA

Although microstrip antennas are very popular in the microwave frequency range due to their simplicity and compatibility with circuit board technology, their limited bandwidth usually limits their usefulness.

Various methods have been proposed to overcome this limitation - including the use of gap or directly coupled parasitic patches. In FEGCOMA, these parasitic strips were placed next to all four edges of the device that drives the patch. A parasitic patch with slightly different resonant lengths is introduced to produce further resonances to improve the bandwidth and gain of the standard patch. In this case, the structure is optimized to obtain a well-defined designable bandwidth with a zero close to the optimal interval. Typical gain values can be expected to be 10 dBi with a designable fractional impedance bandwidth between 12% and 30%.

Normal mode spiral antenna (NMHA) is commonly used in handheld radio transceivers and mobile communications applications. Printing of 50 Ω matching NMHA natural match, therefore avoided when resonance matching typical design challenges of similar structures.

Printing self-matching normal mode spiral antenna

It has similar characteristics to the other NMHAs, namely: it is compact (the total height is usually 0.14 lambda), it is vertically polarized and omnidirectional, and its bandwidth is about 3%.

The helical structure consists of two metal helical strips of equal width (internal and external), with a central dielectric portion between them.

We introduce a non-canonical state for lookup patterns and design patterns, which is useful in workflows that do not require a specific specification.

Fourth, there is no standard workflow

When you select find antenna from the start page, find mode starts in the specification disabled state. Prototypes added to the collection in this mode will have no initial link to the specification and no reference design.

You can use the buttons provided on the ribbon to enable/disable the specification workflow as needed. You can change the selected state individually in find mode and each stereotype.

5. Design scope extrapolation

In some cases, the restrictions imposed by Antenna Magus may be too restrictive. Design range extrapolation (DRE) is introduced to extend the range of supported designs for all devices. When DRE is enabled, the slider and range tooltips for the design target represent extended ranges. DRE is active by default and can be disabled/enabled by navigating to the start page, >, Settings, >, design and estimation. Currently, for any given design, there is only one target that can be extended.

DRE adopts the double-layer design method, using the direct design with Objective values beyond the verification range, and then carries out the second extrapolation stage based on the design within the verification range to find the best possible design prediction. While DRE's approach can produce a good first-order design for almost any situation, DRE may sometimes recommend substandard designs. If DRE fails to find a valid design, a message is displayed.

6. Near-field source export

Now, for most designs and adjustments, you can calculate and output the equivalent near-field data for each 3D far-field. Near-field data cannot be visualized in Antenna Magus, but can be exported in a format compatible with the CST Studio Suite field source. Because near-field computing can degrade performance estimates, near-field computing is disabled by default and must be enabled in Settings. When this setting is off, the estimated design and tuning data is not available.

Array operators

A variety of array operators have been added to the array composition tool. These operators can convert the basic layout (created in Antenna Magus or imported using the *.tsv array layout format) to a more advanced layout. Multiple array operators can be applied in a particular order to achieve the desired layout.

Operators include:

Basic operators such as rotation, translation, and scaling.

Conformal operator that allows a layout to be overlaid or projected onto a geometric surface, such as a parabola or sphere.

Discretization can be used to discretize the phase and amplitude of the operator.

A special operator that performs array operations, such as the loop fragment operator, which attempts to copy and arrange multiple basic layouts in a segmented circular pattern.

Viii. Rotation of Ludwig iii axis

Ludwig III visualization provides a way to compare simulated far-field radiation patterns with measurement patterns in a typical laboratory measurement setting. The common polarization and cross-polarization options provided by Antenna Magus (according to the third coordinate transformation described in the paper: Arthur c. Ludwig, "the definition of cross-polarization", IEEE Antenna and propagation transaction, January 1973) assume that the propagation is in the Z direction and along the Y-axis orientation of the E field.

Since not all antennas in Antenna Magus are directed by this definition, it is not always possible to draw common and cross-polarization in the desired coordinate direction. To solve this problem, Antenna Magus added an additional setting that allows the user to define the direction of the coordinate system used for Ludwig III visualization relative to the global coordinate system.

Nine, export macro

You can now export the design variables and save them as macros/scripts. This can be done from the export pattern or the design pattern. Two formats are currently supported:

VBA macro (*.mcr - supported by CST Studio Suite)

LUA script (*.lua - supported by ALTAIR FEKO 14.0 and later)

Running the macro/script, as described in the supported tooling documentation, updates the values of all the variables named after the Antenna Magus template in the project without affecting any other geometry or post-export modifications. This is especially useful when the derived model is formed after an export or when it constitutes part of a complex assembly.

The Settings menu has been reorganized to accommodate other Settings for the new functionality. These are detailed below. Setup menu and other Settings

X. design and evaluation

New Settings for design-scope extrapolation and near-field source export have been added to the design and estimation TAB. Both are described in more detail in various parts of this newsletter.
