Escribir código para imagen

Question

¿Alguien puede ayudarme a escribir código para la siguiente figura? ¿Quiero insertarlo en una presentación y no estoy muy versado en gráficos?

Answer 1

Esto produce algo bastante similar.

\documentclass[tikz]{standalone}
\usetikzlibrary{intersections}
\begin{document}
\begin{tikzpicture}
\draw[thick] (0,0) -- (10,0) node[above,pos=0.4]{Ground plane};
\draw[latex-latex] (1,-1) -- (9,-1) node[midway,fill=white,minimum width=1cm] {$r$};
\coordinate (receiver) at (9,1);
\coordinate (fakereceiver) at (9,-1);
\coordinate (sender) at (1,3);
\coordinate (fakesender) at (1,-3);
%\coordinate (reflector) at (7,0);
\draw[thick] (sender) -- (receiver) node[above,pos=0.15]{\begin{tabular}{c}
sending\\ antenna\end{tabular}};
\coordinate (reflector) at (intersection of sender--fakereceiver and
fakesender--receiver); 
\draw[thick,-latex] (reflector) -- (receiver) node[above]{\begin{tabular}{c}
receive\\ antenna\end{tabular}};
\draw[thick,-latex] (sender) -- (reflector);
\draw[latex-latex] (0.5,0) -- (0.5,0 |- sender) node[midway,fill=white,minimum width=1cm]
{$h_s$};
\end{tikzpicture}
\end{document}
