【Abstract】 In this paper,measurement techniques are presented for microwave dielectric ceramic devices with the principle of parallel plates, including hardware, software and friendly measurement interface. Different kinds of synthesis techniques are adopted, not only traditional solid-state reaction method but also solution synthesis techniques, in addition to the gel-casting for complex shape of ceramic components and tape-casting for large scale plate of microwave IC. Several kinds of microwave devices are developed, including dielectric resonators, dielectric filters, GPS antennas, filtering connectors of communication cables,and thin substrates for microwave IC,which are applied in different kinds of microwave equipments.更多还原
