| Popis: | 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 Zin ≠ 50 Ω to Zin = 50 Ω offers upgraded impedance bandwidth and compatibility with 50 Ω CPW or coaxial lines. Details of the design procedure and experimental results exhibiting a bandwidth (VSWR |
