Abstract :
A new synthetic quasi-TEM (transverse electromagnetic) transmission line (TL) is presented for achieving higher characteristic impedance (Zc). The proposed synthetic TL consists of a 2D array made of complementary-conducting strips (CCS) unit cell, which permits tuning for desired propagation characteristics of the transmission line under synthesis. Based on the particular case study, both theoretical and measured results agree excellently for the comparative studies for the proposed synthetic TL and the conventional microstrip. The Zc of a synthetic TL is 130% higher than that of a wide microstrip. Furthermore, the extracted slow-wave-factor is 17.7% higher than the physical limit of microstrip.
