<H1><SPAN class=storyheadline>Curved UWB antenna said to be most compact
</SPAN></H1>
<P><FONT face=Verdana><FONT size=3><EM><STRONG>EE Times</STRONG> has published
an article on a curved UWB antenna which it is claimed results in a 2.5-fold
reduction in the size of an ultrawideband antenna</EM> </FONT></FONT>
<P><FONT face=Verdana size=3>Compact antennas are usually one-quarter the length
of the wavelength being transmitted, but Virgina Tech engineers are claiming a
2.5-fold reduction in the size of an ultrawideband antenna. </FONT>
<P><FONT face=Verdana size=3>The compact UWB antenna (CUA) has a curved
multi-element shape twisting around the inside of a spherical shape with a
diameter just one-tenth that of the wavelength being transmitted. </FONT>
<P><FONT face=Verdana size=3>"We needed to know how to build an UWB antenna that
came close to the size limit, and the CUA invention has accomplished this by
fully utilizing the volume of a specified diameter," said Virginia Tech
engineering professor Warren Stutzman. </FONT>
<P><FONT face=Verdana size=3>The CUA's shape seems to extend along the length of
individual antenna elements, longer than its diameter appears, then twisting
around the inside of its radome, or protective housing. </FONT></P>
