Abstract :
Based on the theory of the composite right/left-handed transmission line (CRLH-TL), a novel unit of planar distributed structure for double negative materials (DNM) is proposed. The new unit consisted of a microstrip line is of composite structure only on a single-layer but not two layers as did before by using interdigital capacitor instead of the old capacitor structure, the structure has debased the left-handed frequency band to increase the left-handed working frequency region. Also, the equivalent circuit parameters have been extracted with full-wave simulation
