Abstract: A dual-band substrate integrated waveguide (SIW) cavity backed antenna loaded with complementary split ring resonator (CSRR) metamaterial is proposed for WiMAX/WLAN band applications. This antenna uses a rectangular cavity and CSRR slots on the ground plane for dual band radiation. The rectangular SIW cavity resonator produces two cavity modes TE 110 and TE 120 into free space owing to array of metallic vias. By introducing CSRR, it excites the lower hybrid modes for realizing a low-profile antenna design at 2.5 GHz due to strong coupling effect in the SIW cavity resonator. The mode theory mechanism is utilized for analysis the designed antenna. The geometry of the fabricated antenna is developed on a low cost FR-4 dielectric substrate with dimensions 30 × 30 × 1.6 mm3 to resonance at 2.5 GHz and 5.4 GHz. The experimental S 11 (dB) exhibits a fractional bandwidth of 4% (2.45–2.55 GHz) in the lower resonant frequency of 2.5 GHz and 2.4% (5.33–5.46 GHz) in the higher resonance frequency of 5.4 GHz. The designed antenna possesses significant advantages of low-profile, better S 11 (dB), planar configuration and unidirectional radiation patterns. [ABSTRACT FROM AUTHOR]
