✦ Synopsis

work. By using CSRRs, a very large insertion loss was obtained in the stopband. Because the bandgap characteristic is the behavior of the CSRR itself, not because of the array of the periodic structure, the dimensions of the structure can be made much smaller than in the case of a microstrip line with a periodic perturbation of square pattern on the ground plane. The sub-wavelength resonator is proved to find practical applications in band reject structures with small size. The attenuation and propagation constants of unit cell of this structure were extracted and a physical behavior of stopband of this CSRR loaded microstrip line has been demonstrated.

An on-chip implementation of a low loss 1:9 transmission line transformer (TLT) is presented. The TLT was fabricated with broadside coupled microstrip lines in a GaAs HBT process. The wide metal transmission lines allow the high-quality factor and the high-current capability. The measured insertion

## Abstract A novel Pi‐type branch line is constructed by using two shunt stepped‐impedance stubs in this paper. Introducing the stepped‐impedance stubs increases design degrees of freedom of this Pi‐type line. This structure can be used to replace arbitrary single‐section transmission line in micr
