Wideband Multi-Port Reflectometer as an Alternative in Reflection Coefficient Measurement
Abstract: This paper presents
the characterization and operation of an alternative device, which is known as
multi-port reflectometer to measure the reflection coefficient of any device
under test (DUT). Its configuration is formed by two power dividers (D) and
four couplers (Q). The characterization is evaluated through the centres of
power circles that also known as q-points. Its operation in the reflection
coefficient measurement is tested by using three DUTs. The reflectometer’s good
performance and wideband operation are proven between the frequency band of 1
and 6 GHz via the practical hardware measurement in the laboratory.
