摘要

锥形微带Balun在螺旋天线馈线部分用作阻抗变压器网络，因为它可以在大频率范围内提供阻抗变换，也可以实现单端端口到对称端口的转换。不平衡线到平衡线的转换依赖于线的横截面的逐渐变化。本文介绍了一种2-18 GHz的巴伦微带，该微带使用柯芬斯坦方程来计算锥度。首先在Ansoft HFSS中对Balun结构进行模拟，然后进行制作;模拟结果与实测结果吻合很好。

Klopfenstein tapered 2–18 GHz microstrip balun

Tapered microstrip Balun is used as an impedance transformer network in feeding sections of spiral antennas as it provides impedance transformation over a large range of frequency and also serves the purpose of conversion of single ended port to a symmetric port. The conversion from unbalanced to balanced line relies on a gradual change of cross section of the line. This paper presents a 2-18 GHz microstrip Balun that uses the Klopfenstein equations for the taper. The Balun structure was first simulated in Ansoft HFSS and then fabricated; there was a close match between the simulated and measured results.
