Development of miniaturized microwave components using single and coupled artificial transmission lines







ROC Military Academy


Prof. Hong-Twu Chen


The ever increasing demands for miniaturized microwave components have imposed new challenges to circuit designers. Recently, we investigated a new circuit scheme for synthesizing artificial transmission line using quasi-lumped elements. The proposed artificial line is capable of significantly reducing the required physical length while preserving the electrical properties of a conventional transmission line. By utilizing the proposed artificial transmission lines in either microstrip form, stripline form, or coplanar waveguide form, various microwave components or sub-systems like quadrature hybrid, rat-race hybrid, Butler matrix, broadside coupler, Marchand balun, doubly balanced mixer, multiplexer, dual-mode bandpass filter, etc. have been successfully realized and miniaturized. The occupied sizes of these designs are merely 10~25% as compared to the conventional designs. The circuit configuration, design methodology, and performance will be discussed throughout the lecture.
