绘制电路图

我正在尝试绘制此图，但我陷入了天线文本位置。此外，我对半圆形天线的绘制不满意。我还缺少圆圈内的弯曲箭头。有人能帮忙修复这个问题吗？这张图是否可以改进和优化？

这是一个使用样式和相对定位的选项

\documentclass[tikz, border = 5pt]{standalone}

\usetikzlibrary{arrows, positioning, decorations.markings, calc}
\begin{document}

\begin{tikzpicture}[
    node distance = 1cm and 2cm,

    inner sep = 2pt,
    outer sep = 0pt,
    align = center,
    thick
    ]

  \tikzstyle{duplexer} = [
    draw,
    circle,
    minimum width = 1cm,
    inner sep = 2pt,
    outer sep = 0pt,
    thick
    ]

  \tikzstyle{line} = [
    -latex',
    thick,
    ]

  % nodes
  \node[duplexer] (duplexer) at (0, 0) [label=above:Duplexer]{};

  \draw[line] (duplexer) -- (B);
  \draw[line] (B) -- (duplexer);

并进行了一些修改

\documentclass[tikz, border = 5pt]{standalone}

此解决方案使用matrix节点和anchors作为连接的参考。箭头使用arrows.meta和bend库绘制，从而在双工器中产生更好的内部箭头。

\documentclass[tikz, border=2mm]{standalone}
\usetikzlibrary{arrows.meta, matrix, bending}
\usepackage{lmodern}

\begin{document}
   \begin{tikzpicture}[
        font=\sffamily\scriptsize,
        box/.style={draw, thick, text width=2cm, align=center, minimum width=2cm, minimum height=1cm},
        ball/.style={draw, thick, circle, text width=0pt, minimum size=1cm},
        >={Latex[bend]}]

    \matrix (A) [matrix of nodes, nodes={box, anchor=center}, column sep=.8cm, row sep=.5cm,
        row 1 column 1/.style={nodes={ball}},
        ]{
        {} & Transmitter & {Waveform\\ Generator}\\
        {Low Noise\\ RF Amp} &  & \\
        Mixer & {Local\\ oscilator} & Display\\
        IF Amplifier & {Signal\\ Processing} & {Data\\ Processor}\\
    };

    \draw[<-, thick] (A-1-1)--(A-1-2);
    \draw[<-, thick] (A-1-2)--(A-1-3);
    \draw[->, thick] (A-1-1)--(A-2-1);
    \draw[->, thick] (A-2-1)--(A-3-1);
    \draw[->, thick] (A-3-1)--(A-3-2);
    \draw[->, thick] (A-3-2)--(A-1-2);
    \draw[->, thick] (A-3-1)--(A-4-1);
    \draw[->, thick] (A-4-1)--(A-4-2);
    \draw[->, thick] (A-4-2)--(A-4-3) coordinate[midway] (aux);
    \draw[->, thick] (aux)|-(A-3-3);
    \draw[<->, thick] (A-1-1.west)--++(180:1cm) coordinate (aux2);
    \draw[ultra thick, line cap=round] ([xshift=-1cm]aux2)+(-50:1cm) node[below]{Antenna} arc(-50:50:1cm);
    \node[above] at (A-1-1.north) {Duplexer};
    \draw[->] (A-1-1.center)+(90:.3cm) arc(90:360:3mm);

我只添加了一个新节点，\node at (x,y) {Antenna}并使用 fittet texsize\footnotesize

对于带箭头的弧线，你可以使用\draw[->,>=stealth',thin] (3,15.8) arc[radius=.3, start angle=90, end angle=360];

以下是新代码：

   \node[draw,thick,circle,inner sep=0pt,minimum size=1cm] at (3,15.5) (A1) {};
   \node at (3,16.2) {\footnotesize Duplexer};
   \draw[->,>=stealth',thin] (3,15.8) arc[radius=.3, start angle=90, end angle=360];

\foreach \pos/\txt in {5/Transmitter,8/Waveform Generator} {{\draw[draw=black,thick,text width=2.5cm, align=center] (\pos,15) rectangle ++(2,1) node[pos=.5] {\scriptsize \txt };};}
