| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 103 === In this thesis, a broadband dispersive group delay line with |S21| of all-pass response using cascaded complementary-transmission-line structure is presented. The complementary structure includes mainly shunted open stubs in signal plane and slot-line of the corresponding stubs in ground plane. Transmission zeros of shunted open stubs can be convert to a all-pass response of |S21| by the slot-line of corresponding stubs. In addition, in order to avoid higher order harmonics affect performance in fundamental band, z domain technique is employed to enhance the ratio of higher order harmonic frequencies and central frequency for the shunted open stubs. The formulations for controlling bandwidth of group delay is also derived by z domain technique. Multi-stage cascaded technique is employed to increase the time and bandwidth of group delay.
