Abstract

This paper studies a relationship between input impedance and average characteristic impedance (w), wavelength shorten factor(n) and equivalent diameter through analysis of input impedance date of 76m and 138m antenna and proposes a view on the reason for bigger error of input impedance using transmission line method and a correction method.
