Abstract

In this manuscript, double-negative transmission line (TL) metamaterial-inspired antenna has been proposed with compactness and improved bandwidth. This antenna is made of double-negative meander lines, microstrip feed and partial ground. Double-negative TL metamaterials show negative permittivity and permeability simultaneously and play important role for antenna miniaturization and the impedance bandwidth improved. The antenna provides 600 MHz bandwidth (−10 dB) with 23.81% fractional bandwidth. The antenna radiating element size is 0.07λ × 0.07λ at 2.51 GHz frequency with 3.72 dBi maximum gain where the electrical dimension is 0.30λ × 0.30λ.
