这不是什么新鲜事。但解决方案如下：
我无法让它发挥作用。
基本上我想要的是定义一个命令，它将是一张图片，并且可以在其他图片中用作节点，类似于形状的定义方式。这样我就可以重复使用代码，因为每张图片都有许多元素。参见 MWE：
\documentclass{standalone}
\usepackage{ellipsis}
\usepackage{tikz}
\usetikzlibrary{calc}
\usetikzlibrary{decorations.pathreplacing}
\usetikzlibrary{shapes.geometric}
\newcommand{\MUE}[1]{%
\begin{tikzpicture}
\node[draw, shape = rectangle, minimum width=15mm, minimum height=7.5mm] (box) {#1};
\draw ($(box.south west)+(0.25,0)$) circle (4pt);
\draw ($(box.south east)-(0.25,0)$) circle (4pt);
\draw[fill=black] ($(box.south west)+(0.25,0)$) circle (1pt);
\draw[fill=black] ($(box.south east)-(0.25,0)$) circle (1pt);
\draw ($(box.north west)+(0.25,0)$) -- +(0,0.25) node[midway] (ant1) {};
\draw ($(box.north east)-(0.25,0)$) -- +(0,0.25) node[midway] (ant2) {};
\node at ($(ant1)!0.5!(ant2)$) {\dots};
\draw (ant1.north) -- +(135:0.25);
\draw (ant1.north) -- +(45:0.25);
\draw (ant2.north) -- +(135:0.25);
\draw (ant2.north) -- +(45:0.25);
\end{tikzpicture}
}
\newcommand{\MBS}[1]{%
\begin{tikzpicture}
\node[draw, shape = dart, shape border rotate = 90, minimum width = 10mm, minimum height = 10mm] (base) {#1};
\draw[line join = round] (base.110) -- (base.70) -- (base.north west) -- (base.north east) -- cycle;
\draw ($(base.north)+(0.5,0)$) -- +(0,0.25) node[midway] (ant1) {};
\draw ($(base.north)-(0.5,0)$) -- +(0,0.25) node[midway] (ant2) {};
\draw[cap = rect, line join = round] (ant1.south) -- (ant2.south);
\node at ($(ant1)!0.5!(ant2)$) {\dots};
\draw (ant1.north) -- +(135:0.25);
\draw (ant1.north) -- +(45:0.25);
\draw (ant2.north) -- +(135:0.25);
\draw (ant2.north) -- +(45:0.25);
\end{tikzpicture}
}
\begin{document}
\begin{tikzpicture}
\node[draw, shape = circle, fill = yellow!30] at (0,0) (test1) {\MBS{BS}};
\node[draw, shape = circle, fill = blue!30] at (3,3) (test2) {\MUE{UE1}};
\node[draw, shape = circle, fill = blue!30] at (3,-3) (test3) {\MUE{UE2}};
\draw[->] (test1) -- (test2);
\draw[->] (test1) -- (test3);
\end{tikzpicture}
\end{document}
可以看出，图片中的天线放置不正确，因为我使用的是draw, shape = circle第二张图片中的节点。此外，如果我添加，inner sep = 0pt结果会更糟。我如何在 TikZ 中使用这种嵌套？
答案1
这里不要使用节点；既不要标记路径上的位置（您可以使用coordinate来实现），也不要回到该线的顶点，只需使用您已经在那里使用的路径（您可以在 之后使用 路径node）或重新计算坐标或使用移动到那里（--在您的路径中省略 ）。
我还提供了一种antenna insert path采用一个参数的样式，即坐标号，其余的是相对（+）以及相对和移动到（++）运算符的混合。
宏也是如此\MBS。在这里，我选择用零绘制dart，outer sep这样锚点就位于线的中间（这需要与绘制天线部分相反（注意yshift=.8pt来自thick与样式一起使用的线宽）。
我注释了原来的位置，\dots并添加了另一种放置点的方法，即使用label（\MUE）和路径上的节点（\MBS）。
您可以不使用它。
