Measurement of the effective relative permittivities of microstrip
Electronics Letters, 1975 A new method for determining the effective relative permittivity of microstrip, even at high frequencies, is presented. Four microstrips having the same physical and geometric characteristics, but different lengths, are needed; the mismatch due to the launchers is completely overcome.
