SIZE REDUCTION OF KLOPFENSTEIN-BALUN TRANSFORMER FOR BALANCED ANTENNAS

A BALUN transformer converts impedance into another one and also an unbalanced line a balanced line. compact size broadband is designed using Klopfenstein taper approach to transform 50Ω 100 Ω. The results of the conventional are compared with proposed BALUN. In order reduce length BALUN, curved microstrip used. 56 %- 70 % smaller in w.r.t but at cost 6% - 11% reduction overall band. has measured bandwidth 165 while reduced 159. agreement simulated results.
