Abstract

A metamaterial-inspired compact patch antenna resonating between 2 and 6.3 GHz for various wireless standards is proposed. The antenna is a patch antenna that is loaded with a metamaterial-inspired loading structure and is fed using a coplanar waveguide feed line that has been designed to have a characteristic impedance of 50 Ω. The compact antenna is a wideband antenna with a bandwidth (below −10 dB) of 4.3 GHz. The size of the patch in terms of the free-space wavelength at the lowest resonance frequency is λ 0/11×λ 0/7×λ 0/90. The large bandwidth of the antenna is obtained by loading a conventional patch antenna with a metamaterial-inspired loading structure that has been designed to resonate at its lowest fundamental left-handed mode, near to the conventional patch’s resonant frequency.
