Abstract

In this paper, we introduce the concept of ICTL(inductively compact transmission line) that is new type of compact transmission line. As using the ICTL, the compact microstrip hybrid rat-race coupler was designed. It's new type compact rat-race couplers. The designed compact rat-race cooper at 1.8 GHz has area of 1182 $mm^2$, and it is $58\%$ for conventional rat-race couplers. Measured results are agree with predicted results.
