Coplanar waveguide-fed dual exponentially tapered slot antennas for ultra-wideband applications

Abstract

A miplanar c~planar waveguide-fed dual cxpme"tia1ly tapered slot antema is pmposed, using a lumpsd-slcmcnt impedance-(ransforming coplanar w~veguide-ta-rlotline transition as Ihe antenna f d m g structure. The pmpased ante-features a compact ~i i e , wide impedance bandwidth, and ~miisfenl radiation pallems over the low-band of ultrawidsband (mvs) specr". In this work, the characleristicr ofpropsrsd antenna both in frequency and time domains are cmfully investigated. It is dcmonrtatsd that minimum distorlion to Le UWB input p u k can be sxpsoted.
