Header in Middle of Top Rule

Question

I am trying to create a header so that it looks like the image below such that the header is not right on top of the first line

However, I played with the dimensions on this MWE and can't seem to get it to work. I am wondering if I may be able to get some insight on how to do this.

\documentclass[12pt]{article}

\usepackage{fullpage} %full page typesetting
\usepackage{setspace} %allows for non-singlespacing
\usepackage{graphicx} %graphics capabilities
\usepackage{latexsym} %extra symbols
\usepackage{rotating} %rotation for figures
\usepackage{longtable} %tables that fill more than a single page
\usepackage{hyperref} %hypertext links in the document
\usepackage{natbib} %better bibliographies
\usepackage{authblk} %author and affiliation in opening


%Put name and page number on subsequent pages
\usepackage{fancyhdr}
\pagestyle{fancy}
\fancyhf{}
\setlength{\headheight}{14.5pt}
\rhead{\emph{Some Header}}
\cfoot{\thepage}
\renewcommand{\headrulewidth}{0pt}


\newcommand\e{\emph}
\newcommand\tb{\textbf}
\newcommand\un{\underline}
\newcommand\txt{\texttt}

\usepackage{blindtext}

\begin{document}
    \blindtext 
\end{document}
