A novel microstrip balun topology based on common‐mode rejection is introduced. The balun is constructed with a short section of coupled line placed above a defected ground structure. Measurements on a PCB sample indicate a successful conversion from single end to differential mode showing 0.7 dB of insertion loss at 3 GHz along with 1‐dB bandwidth that extends from 0.7 to 5.6 GHz. © 2012 Wiley Periodicals, Inc.
