How to remove the short title emplacement from ANTIBES theme in beamer

Question

I'm working with the Antibes theme in beamer which gives me the ability to show current section and subsection but also the Shorten title whcich I want to remove and save this space for the rest. I want to save the space which shown in the figure in red.

I googled this for a long time but I still whitout responses ...

\documentclass{beamer}
\mode<presentation> {

\usetheme{Antibes}

\setbeamertemplate{footline}[page number] % To replace the footer line in all slides with a simple slide count uncomment this line

 \author[My Name]{} 
 \institute[Lab Name]{ complete lab name }

 \title[]{Analyse d’images satellitaires } 

 \begin{document}

  {
 \setbeamertemplate{headline}{}
 \begin{frame}
 \titlepage
 \end{frame}


 \section{section one}
 \begin{frame}

 \subsection{subsection one}

 \end{frame}


  \section{section two}
  \begin{frame}

   \subsection{subsection two}
  \end{frame}

   }


   }

Thank you

You can define your own headline and exclude the box with the subtitle:

\documentclass{beamer}

\usetheme{Antibes}

\setbeamertemplate{footline}[page number] % To replace the footer line in all slides with a simple slide count uncomment this line

 \author[My Name]{} 
 \institute[Lab Name]{ complete lab name }

 \title[]{Analyse d’images satellitaires } 

\makeatletter
\setbeamertemplate{headline}
{%
    \begin{beamercolorbox}[wd=\paperwidth,colsep=1.5pt]{upper separation line head}
    \end{beamercolorbox}
%    \begin{beamercolorbox}[wd=\paperwidth,ht=2.5ex,dp=1.125ex,%
%      leftskip=.3cm,rightskip=.3cm plus1fil]{title in head/foot}
%      \usebeamerfont{title in head/foot}\insertshorttitle
%    \end{beamercolorbox}
    \begin{beamercolorbox}[wd=\paperwidth,ht=2.5ex,dp=1.125ex,%
      leftskip=.3cm,rightskip=.3cm plus1fil]{section in head/foot}
      \usebeamerfont{section in head/foot}%
      \ifbeamer@tree@showhooks
        \setbox\beamer@tempbox=\hbox{\insertsectionhead}%
        \ifdim\wd\beamer@tempbox>1pt%
          \hskip2pt\raise1.9pt\hbox{\vrule width0.4pt height1.875ex\vrule width 5pt height0.4pt}%
          \hskip1pt%
        \fi%
      \else%  
        \hskip6pt%
      \fi%
      \insertsectionhead
    \end{beamercolorbox}
    \begin{beamercolorbox}[wd=\paperwidth,ht=2.5ex,dp=1.125ex,%
      leftskip=.3cm,rightskip=.3cm plus1fil]{subsection in head/foot}
      \usebeamerfont{subsection in head/foot}%
      \ifbeamer@tree@showhooks
        \setbox\beamer@tempbox=\hbox{\insertsubsectionhead}%
        \ifdim\wd\beamer@tempbox>1pt%

    \begin{beamercolorbox}[wd=\paperwidth,colsep=1.5pt]{lower separation line head}
    \end{beamercolorbox}
