  • Abstract Abstract
    This thesis mainly presents a broadband CPW-to-CPS transition using broadside-coupled strips, instead of microstrip radial stub, to reduce the overall area of transition. The transition is composed of CPW-MS and MS-CPS transition. Using IE3D electromagnetic simulation software to simulate CPW-MS and MS-CPS transition and to realize in back-to-back configuration. In CPW-MS and MS-CPS transition, both simulation and measurement are in good agreement. Hence, to merge the two transition and it found that both simulation and measurement are in good agreement in back-to-back configuration. Overall, the 1-dB insertion loss and 15-dB return loss bandwidth for the back-to-back transitions is from 6.5 GHz to 13.5 GHz. The back-to-back transitions also have a 20-dB return loss bandwidth from 8 GHz to 12 GHz. Besides CPW-to-CPS transition, this thesis also uses IE3D software to simulate conventional compensation of T-junction. It found the design of conventional compensation of T-junction are not suitable, when frequency is from 25 GHz to 35GHz.
