Abstract

In this paper, the RF characteristics of the flexible Kapton-based substrate are investigated by using the microstrip ring resonator in order to characterize the relative permittivity (εr) and loss tangent (tanδ) of the substrate at Ultra Wide Band (UWB) range. A compact notch filter using the approach of phase cancellation between two signal paths is also reported here. The passive notch filter is designed onto a Rogers4003-based substrate to test its performance. The integrated silicon chip is then reported on a grounded area of filter and connected to the output of this later by wire-bonding forming an SIP (System In Package) approach. The complete design is fully simulated using HFSS simulation tools, featuring high rejection at the central frequency and very low insertion loss far from the notch frequency.
