Symmetric Coupled Composite Right-/ Left-handed Transmission Line in Common-/ Differential-mode Operation

In this paper, a novel four-port symmetric coupled composite right-/left-handed (CRLH) transmission line in common/differential-mode operation is introduced. The symmetric metamaterial structure is based on a unit-cell which under a differential-mode excitation behaves like a CRLH metamaterial with bandpass filter characteristics. In contrast, the CRLH… CONTINUE READING
