摘要：

A new ultra-wideband balun and its application for balanced antenna are presented in this paper. To realize the balun-type function, two different types of microstrip to slotline transition forms are adopted for the unbalanced and balanced outputs of the balun. Further, an ultra-wideband balun and its integration with a Vivaldi antenna are designed and fabricated to validate the feasibility of the new approach. Results indicated that the proposed balun and the antenna can operate from 3.6 to 10.7GHz. For the proposed new balun, it exhibits a good balanced performance of within 0.5dB magnitude imbalance and less than 6 degrees phase imbalance between the two balanced outputs. Meanwhile, the antenna reveals good unidirectional radiation patterns.
