Transmission Lines: Reflection Coefficient vs Frequency

  1. Nov 17, 2014 #1
    Hey guys - Ive been using this website to study transmission lines. (great study aid - posting for others to use. Great for smith charts) However, Ive noticed this graph they have for load matching:

    I'm having trouble finding or understanding a relationship for reflection vs frequency. Ive never used frequency for a reflection coefficient, but clearly there is a relationship. Even for an all real load. Can someone share some wisdom?

    Reflection coefficient is some function of frequency too. Apparently it's dependence vs frequency is weak for long, low frequency signals and can be taken for constant. But 1 Ghz...this frequency is pretty high for transmission lines.
