A broadband end-fire antenna loaded with magneto-electro-dielectric metamaterial (MEDMTM) is presented in this paper. Based on a planar printed structure, many periodic structures are investigated in antenna design. The metal patch is embedded with a C-shaped complementary split-ring resonator (CSRR) array, and many cross slots are etched on the ground plane. The zerothorder resonance (ZOR) and first-order resonance (FOR) can be excited. As a result of electromagnetic coupling effect, the C-shaped patch and ground plane compose metamaterial transmission line (MTL). For potential applications, the broadband and end-fire antenna can work with a 53.5% (3.81–6.59 GHz) impedance bandwidth. The proposed antenna achieves size reduction, gain improvement and bandwidth enhancement.
