Abstract :
A new technique using the multi-port annular slot antenna for the measurement of complex permittivity is developed. The benefit of this new technique is that a two port network can be used on a planar device without excision of the sample. A simple but effective calibration technique to compensate for the feed network is used to obtain the measured permittivity for methanol. The validity of the method is confirmed by comparing the expected and measured results.
