This paper presents the design and implementation of a novel fully planar modified, extended composite right/left-handed transmission lines (E-CRLH-TLs) utilizing a complementary split ring resonator (CSRR) loaded on the ground plane. The multiband behavior of the proposed layout is demonstrated by an equivalent circuit which in this case is distinct from the standard form of the equivalent circuits presented for an E-CTLH-TL; therefore, in order to design a quad band E-CRLH unit-cell, the design procedure is investigated. The main advantages of the proposed layout over other topologies are size reduction and fabrication simplicity which are proved by the design and fabrication of a quad-band Y power divider.
