CPW Transmission Insertion Loss on Si and SOI Substrates

The transmission loss properties of coplanar waveguide (CPW), built on bulk silicon and low and high resistivity silicon-on-insulator (SOI) substrates, are investigated systematically in this article. The experimental results show that the insertion lo...
Coplanar waveguides are widely used in MMICs as interconnects and matching networks. Designing low loss, multifunctional and highly integrable transmission lines is a key factor in obtaining high performance from MMICs in silicon technology. 1 Nevertheless, the low resistivity of a standard silicon substrate deteriorates the performance of on-chip...

A UWB Filter Using a Dual-mode Ring Resonator with Spurious Passband Suppression

A novel, compact, microstrip bandpass filter for ultra-wideband (UWB) radio systems is proposed. This filter has a 3 dB fractional bandwidth of 60 percent, with low insertion loss and sharp rejection. Based on a dual-mode ring resonator structure and w...
The investigation of the use of ultra-wideband (UWB) has been one of the most controversial technologies of modern times. Its applications can be seen in diverse areas such as local area networks, position location searching, advanced imaging of the human body, etc. Microwave ring resonators are the components proposed...
