This paper presents a dual-band bandpass filter by introducing transmission zeroes in the passband of a broadband bandpass filter using square-loop dualmode resonators. The transmission zeroes are achieved by using a dual-mode resonator. The dual-mode resonator is attached to two transmission lines of the same length. These lines are coupled to similar transmission line that are attached to the...

On-chip transmission line modelling and design become increasingly important as frequencies are continuously going up. This paper explores possibilities to implement transmission lines on CMOS ICs via coupled coplanar strips. EM-field simulations with SONNET are used to estimate important transmission line properties like characteristic impedance, propagation velocity and loss in a 0.18 micron ...

This contribution presents a time-domain model of the skin depth effect in a lossy transmission line. The model was developed and implemented in VHDL-AMS for a twowire edge coupled line but it is general and can be used for other types of lossy transmission line and high-frequency applications with skin depth effect. The salient feature of the model is the use of signal variation rate instead o...

A novel backward microstrip coupled-line coupler which has been designed based on the metamaterial and composite right/left handed (CRLH) transmission line (TL) concepts is proposed. Coupling coefficient, bandwidth and size of proposed microstrip coupler are improved by coupled interdigital TLs which have been realized only by one interdigital capacitor. The design procedure to reach the couple...
