Double Side Parallel Strip Line and its Applications

The recent researches on double side parallel strip line (DSPSL) in City University of Hong Kong are introduced in this paper. DSPSL and its newly proposed variations have been finding more and more applications in microwave passive and active components for miniaturizing and performance improving. Several components based on DSPSL will be discussed in this paper. A novel solution for the exploiting DSPSL in MMIC design is proposed at the end of the paper.
