摘　　要：通过对传输功率增益TPG的进一步推导,引入了共轭匹配原理,提出了一种对实频法的改进算法,运用最小二乘法直接求取电阻折线各段的增量值,避免了对增量的最初选取,简化了计算。用改进实频法设计了一个短波天线宽带匹配网络,在简化算法的基础上取得了比较好的性能。By the further deducing in Transducer Power Gain (TPG), the theory of conjugation matching is introduced in this paper. An improved Real Frequency Method (RFM) is proposed to obtain the resistance increment directly, avoiding the initial guess to them, by the least square method in a simpler way. An example, which is to design a broadband matching network for a shortwave antenna by the improved RFM, gains good performance while simplifying the calculation.
