摘要：

A novel three-dimensional high-isolated dual-band balun is proposed for the first time. A horizontal feeding plane, a vertically mounted plane, and four grounded resistors constitute the entire structure. By introducing the double-sided parallel-strip line with an inserted conductor plane to the middle of the vertical plane, the output matching and isolation, frequency-independent phase difference, and complete ground in the bottom layer of the horizontal plane are perfectly integrated in this novel balun. To prove this conception, a practical balun operating at 1.3/2.5 GHz is designed. As expected, remarkable consistency between the simulation and measurement is obtained.
