Abstract:
Dielectric permittivity is one of the main performance parameters.For discussing the calculation of dielectric parameters of microwave dielectric material,the model of the resonant method was analyzed and based on resonance method,the system of measuring the dielectric parameters was developed.Measurement results show that measurement value agreed with reference value well.The paper also evaluated the uncertainty of the measurement result.So microwave dielectric material permittivity measurement platform in microwave frequency band was established.Keywords:

The method is based on perturbing the fringing field at the open end of the transmission line by an unknown dielectric material, and is applicable not only for solid dielectric materials but also for liquids and gases. Forming or shaping of solid dielectrics is not required, but there should be a small area available for contact. Thickness of the dielectric material terminating the line does not affect the measurement unless the material is thinner than twice the spacing between conductors of the coaxial line. The experimental results obtained for some solid dielectric materials, liquids, and biological tissue shows that the method has sufficient accuracy for most applications up to about 4 GHz.

We carried out comparative analysis of the methods that are used for measuring of dielectric permittivity of liquid dielectrics in microwave range of radio waves. In order to investigate liquids with small and average losses the most widely used methods are the resonance methods using closed volume resonators. The principles of the measurement and construction of the systems are discussed.

Several methods have been described to measure the permittivity of dielectric substrate, and all used the complete area of the sample and so give an average value of this parameter. But in the realization of microwave integrated circuits it is important to know dielectric parameters of the substrate at the point where the component is located. For this local characterization, we propose a method in which the substrate is in sandwich between two similar dielectric resonators. This non destructive method permits to determine the permittivity of a small area (few mm2) of the substrate, by comparing the measured and calculated resonant frequencies of the studied structure.

This paper presents a method of measuring the temperature coefficient of the material permittivity and the coefficient of thermal expansion of dielectric resonators in a purely electrical way. The radial mode matching method has been succesfully applied to the accurate analysis of the test structures containing dielectric resonators.

Systems with interconnects are often limited in their high frequency performance by material properties, particularly dielectric constant and resisitvity, rather than by design issues. Understanding and evaluating materials prior to using them in a system can be vital to achieving required system performance. We present the measurement of dielectric constants and dissipation factors from lMHz to I.8GHz for a variety of electronic and packaging materials using an Agilent 4291B RF impedancelmaterial analyzer with dielectric test fixture. We compared these data with published values and found good agreement.

In this paper measurement technique of the complex permittivity of the dielectric materials over a wide frequency band using the waveguide-dielectric resonator based on a circular evanescent waveguide has been presented. Permittivity and the loss tangent of a dielectric of the fluoroplast-4 have been measured for the H11p mode in the frequency band 9.5−13.5 HGz. A comparison between of the obtained parameters and data of the reference book and original papers has been made.
