本文介绍了宽带阻抗匹配的真实的频率技术的两个改进。所有宽带匹配技术的一个基本限制是均衡器阻抗的真实的和虚部必须通过希尔伯特变换相关联。结果表明，额外的自由度在希尔伯特变换，从而更好的匹配，可以通过采用均衡器阻抗与非最小电抗，并通过优化均衡器电阻以外的规定的带宽。将提出一个细导线偶极天线的例子。
This paper describes two modifications to the real frequency technique of broadband impedance matching. A fundamental limitation of all broadband matching techniques is that the real and imaginary parts of the equalizer impedance must be related by the Hilbert transform. It is shown that additional degrees of freedom in the Hilbert transform, and thus a better match, can be obtained by employing equalizer impedances with nonminimum reactance and by optimizing the equalizer resistance outside the stated bandwidth. Examples will be presented for a thin wire dipole antenna.
