Abstract
The single-section couplers are narrow band devices, so in order to.. broadcn the useful
bandwidth, three-section couplers are used. In this papcr a system of two of three-section
couplers is used to construct a six-port reflectometer. The realized six-port reflectometer is
calibrated and used to measure different unknown complex terminations. The results of thc sixport
reflectometer is found to Le in good agreement with the measurements of the vector
network analyzer (HP-85 1OC) with an error not exceeding 4% in magnitude and 4' in phase in
the frequency range (2.4-4.4GHZ).
