The characterization of passive component properties over a wide frequency range is usually done using scattering parameters. This paper presents the measurement and modeling approach for two typical three-phase mains chokes (3×100μH, 230V, 60A and 3×2.3mH, 230V, 65A) based on six-port scattering parameters using a common two-port vector network analyzer. The model allows to reproduce consistently...
This paper describes two different methods for examination of SMA connector properties. One method is based on measurement of connector scattering parameters and the second method is based on measurement of frequency dependent input impedance of manufactured sample. The sample consists of short microstrip line segment with 50 Ω characteristic impedance and of two edge mounted SMA connectors. The properties...
A balanced fed antenna for the portable radio terminal is received increasing attention due to reduction of the human influence. Recently, a technique called S-parameter method using a standard network analyzer has been proposed whereby the differential impedance can be found. In this paper, four compensating methods using cascade matrices are adopted to reduce the influence of a jig for the S-parameter...
This paper presents comments on measuring the impedance of balanced antennas by an S-parameter method. This also presents an equivalent two-port network for the balanced antenna.
