A zeroth-order resonator antenna using epsilon negative meta-structured transmission line

A novel antenna using ZOR of the ENG MTL has been introduced. The zeroth-order resonant characteristic of the ENG MTL has been described based on the circuit theory and dispersion relations. The fabricated ZOR antenna with 3-stage ENG MTL has been a zeroth-order resonance frequency of 10GHz. The measurement results show good agreements with those of theory and full-wave simulation.
