An electrically small ultra-wideband antenna for mobile handsets and computer networks

摘要

An antenna arrangement (1020) for use in instantaneous ultra-wideband applications, the arrangement using a coaxial to coaxial aperture connection which increases matching bandwidth with reduced lossy effect. Beneficially the antenna arrangement uses a top loaded disk (27) to increase its capacitive effect. The arrangement is physically small making it useful for use within mobile handsets and computer networks.
