I want to show the height in a cross-section: t in the figure 1. But because it is very short, the arrowheads cross each other.

enter image description here

But it should be more like this

enter image description here

My current code is:

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows}

\begin{document}


\begin{figure}[!htbp]
    \centering
    \begin{tikzpicture}
        \filldraw[color=black, fill=black] (0,0) rectangle ++(9,0.5) node[pos=.5](gnd){};
        \filldraw[color=black, fill=gray!20] (0,0.5) rectangle ++(9,2.5) node[pos=.5]{\(\varepsilon_r\)};
        \filldraw[color=black, fill=black] (3.5,3) rectangle ++(2,.2) node[pos=.5](cond){};
        \draw[>=triangle 45, <->] (1,0.5) -- (1,3) node[pos=.5,anchor=west](){\(h\)};
        \draw[>=triangle 45, <->] (3.5,3.4) -- ++(2,0) node[pos=.5,anchor=south](){\(W\)};
        \draw[>=triangle 45, <->] (5.7,3) -- ++(0,0.2) node[pos=.5,anchor=west](){\(t\)};
    \end{tikzpicture}
    \caption{}
    \label{fig:microstrip_geometry}
\end{figure}




\end{document}

  • Hello! Welcome to Tex. For future question please provide the full code with \documentclass{} and preamble etc as MWE, so that others do not have to guess which packages you are loading. – Roland Dec 14 '20 at 06:36
