摘要

A novel design of a compact Ultra-Wideband (UWB) phase shifter with a new stub shape is presented in this paper. The proposed structure is formed using three layers of conductors interleaved with layers of substrates between each of the conductor's layers. This multilayer technique was proposed to realize a design that is small in size, and a 23 mm x 50 mm compact phase shifter design was accomplished. In addition, the implementation of tapered transmission line techniques improved phase shifter performance, when compared with the conventional design without tapered transmission lines. A parametric study on the tapering of the transmission lines is presented and discussed. The measurement results of the phase shifter satisfactorily agreed with the simulation results. The phase shifters measured results demonstrated +/- 5 degrees phase deviation over the UWB frequency range. Moreover, the proposed phase shifter stubs successfully achieved 30% size reduction in comparison with the other available UWB phase shifter.
