Two multi-band balanced bandpass filters (BPFs) are proposed by embedding multi-band coupled complementary split- ring resonators (C-CSRRs) into a balanced stepped-impedance microstrip-slotline transition structure. The proposed C-CSRR is made from two or three nested CSRRs with a pair of coupling s...
