heal.abstract	This letter presents novel modified coplanar waveguide (CPW) bow-tie slot printed antennas fed by a CPW-to-CPW transition. The proposed modules are miniature shaped, low-profile radiators with bidirectional radiation characteristics, which can be optimally integrated in future ultra wide band transceivers. An innovative asymmetric bow-tie configuration is introduced for the first time and the use of inductively coupled slots for bandwidth enhancement is additionally proposed and experimentally studied. The incorporated tapered CPW-to-CPW transition from Z(in) not equal 50 Omega to Z(in) = 50 Omega offers upgraded impedance bandwidth and compatibility with 50 Omega CPW or coaxial lines. Details of the design procedure and experimental results exhibiting a bandwidth (VSWR <2) of 123% are presented. (C) 2006 Wiley Periodicals, Inc.	en
