CSS Underline variation in IE8

I am working on a page which has searched result set. I am using a anchor tag for开发者_StackOverflow社区 displaying the URL and the URL is UNDERLINED.The underline is very close to the text in IE8. Working fine in FIREFOX and IE7 but have a problem with IE8. Here is the CSS class i am using

.search_results_item a {
    color: #20A3E7;
    font: 13px/17px AntennaRegular,Arial,Helvetica,Sans-serif;
    text-decoration: underline;
}

you can always use border-bottom :)

Just see below the link
