Analysis of balanced composite right/left handed structure based on different dimensions of complementary split ring resonators

In this paper, rectangular shape complementary split ring resonators ( CSRRs) with different dimensions are introduced to realize balanced composite right/left handed ( CRLH) structure. As the dimensions of CSRRs is altered, the required series capacitance should also be modified and the propagation characteristics will be changed, which gives the facility of designing microwave/RF components using the balanced CRLH structure. The propagation characteristics of proposed structures are demonstrated by simulated and measured results, which are in good agreement.
