Abstract
This paper presents the radiation rate formula due of a inclusion of a series capacitor and shunt inductor in a unit cell for the right/left-handed transmission line (RLH-TL). The equivalent circuit for a RLH unit cell considering radiation effects is presented and analyzed in terms of the Bloch impedance and dispersion diagram. It has been found that when two radiation rates are identical, the Blockimpedance reduces to the characteristic impedance of the host conventional RH-TL. Besides, design equations for a unit cell for a specific phase shift at a given frequency are provided. The method of realizing uniform excitation along the RLH-TL is also proposed for antenna applications.
