A metamaterial-inspired compact patch antenna resonating at 5.5 GHz for Wi-MAX application is proposed. The antenna is fed by a coplanar-waveguide (CPW) feedline that has been designed to have a characteristic impedance of 50Ω. The compact antenna is also a wideband antenna with a bandwidth (below -10 dB) of 1.3 GHz in the said frequency range, with a gain of 2.2 dB. The size of the patch in terms of the free-space wavelength is λ0/15 x λ0/9 x λ0/29. The wide bandwidth of the antenna is achieved by inductively loading the single patch through the incorporation of the slot.
