| Summary: | The paper proposes a Composite Right/Left Handed
double periodic transmission line structure with both inductance and
capacitance loaded. The structure exhibits leaky wave radiation
and hence can be considered for leaky wave antenna (LWA)
applications. We have theoretically obtained dispersion characteristics
using Singular perturbation method. Also, the radiation e±ciency has
been obtained for di®erent modulation indices. A novel leaky wave
radiation has been obtained below the left handed passband with
narrow bandwidth. The proposed structure has been fabricated on
FR4 substrate and measured. The simulated and measured results
seem to be in good agreement. |
