Abstract:
A CRLH resonator-based band-pass filter includes at least two CRLH resonators. The resonators are connected by capacitive coupling. The resonators includes a microstrip line having input and output ports. The microstrip line includes a first interdigital line serial-connected to the input port, a second interdigital line serial-connected to the output port, a connection line connecting the first and second interdigital lines, and an inductor line parallel-connected to the connection line and provided with a grounded end.
