ABSTRACT:
Improved portability of telecommunications devices demands constant technological advances on many fronts. Of particular importance are methods of constructing and characterising miniature and efficient passive components such as capacitors, filters, antennas and strip-lines that play a pivotal role in the operation of analogue radio-frequency front ends. In this talk we will take a look at the performance of some new materials manufactured by the Functional Materials group in the Research School of Chemistry here at ANU. These materials have state-of-the-art values of relative dielectric constant (~80) and quality factor (Q~10000). The subject of this talk will be a short discussion of techniques to measure the relative dielectric constant over the wide range of frequencies used in the industry.
