Abstract

In order to accurately design microwave, millimeter-wave components and circuits, a simple and accurate method for extracting extremely wideband characteristics of the printed-circuit-board (PCB), including relative dielectric constant, dielectric loss tangent and equivalent copper conductivity, is proposed and validated in this paper. By properly designing the circular substrate integrated waveguide (CSIW) cavity to let its resonating modes distribute within a wide frequency band, extremely broadband properties of the PCB can theoretically be extracted with only one pair of CSIW cavities. The proposed method overcomes the limitations of conventional methods that only support narrowband applications, require a large number of cavities and have relatively large errors. Experiments show that the proposed method is able to extract, accurately and efficiently, the 8-110 GHz characteristics of a TLY-5Z substrate based PCB. And, the extracted results are verified by designing and measuring a fourth-order Chebyshev filter at X band.
