Abstract

Abstract : A planar balun based on using parallel‐coupled microstrip lines is presented. It is designed to transfer the unbalanced microstrip line to a balanced coplanar stripline as needed in many applications such as centre‐fed dipole antennas. The balun includes a T‐junction of stepped‐impedance and tapered microstrip lines and two pairs of stepped‐impedance parallel‐coupled lines. The designed balun covers the band from 3 to 11 GHz with less than 0.4 dB insertion loss.
