Abstract

In this paper, a novel balun which can be applied for a microstrip-to-slotline transition is presented. This proposed balun has a DGS (defected ground structure) pattern on the ground plane. This balun has an advantage that does not require any addional electrical length. The proposed microstrip-to-slotline transition can be made to have power division and 180 degree out-of-phase characteristics. The DGS pattern on the ground plane decides the operating frequency of the proposed balun. In addition, the balun with a VPDGS (vertically periodic defected ground structure) pattern on the ground plane is presented, designed, fabricated and measured
