Abstract
Strip-line has been proposed as suitable for measurement heads in microwave moisture meters. The dependence of the insertion loss of asymmetric strip-line on the dielectric properties of materials in contact with it is discussed. It is shown that only the real part of the complex permittivity has any effect on the measured insertion losses. It is also shown that such effects as are measured are not due to reflection losses. A method of determining εr’ of unknown materials is proposed.Keywords
