Wideband Power Divider Using Novel Split-Ring Resonator
Keywords:
Compact, power divider, Split Ring Resonators (SRRs)Abstract
A set of novel split-ring resonator basic block Hybrid-Microwave Integrated-Circuit (HMIC) components (transmission line, open and short stubs) is presented with applications to the RF/Microwave power divider. This new open and short LH HMIC resonators have compact sizes of 0.81 and 1.44 mm2 , respectively. The prototypes of an LH power divider constructed from these basic components have been designed, fabricated, and characterized. The LH power divider including two LH branches shows equal power split from 1 to 7 GHz. The proposed power divider benefit from the miniaturized LH HMIC components and have compact sizes of 2.205 mm2 , respectively. There is a good agreement between the full-wave simulations and measurement results with 0.254-mm thick RT5880 substrate. While maintaining similar performance, a 50% reduction in impedance transformer is achieved in comparison to a conventional design.
