Abstract :
In this paper the traditional tapered microstrip balun transformer is modified by bending its whole structure to significantly reduce its length. The resulting bent tapered microstrip balun is then extended with a twin-semirigid line to simplify antenna feeding. The decoupling coefficient of the proposed balun has been found to be smaller than -30 dB.
