Abstract:	The paper presents a probe fed slotted hexagonal patch antenna and emphasizes on antenna performance after suppression of a spurious radiation. To suppress the spurious radiation two complementary split ring resonators (CSRRs) are inserted in the reduced ground plane. Based on simulated antenna performance characteristics such as reflection coefficient, impedance and far field radiation pattern of the CSRRs embedded antenna have been analyzed and compared with the antenna without CSRRs. Equivalent circuit model of the antenna with CSRRs has been incorporated to explain the effect of CSRRs on antenna scattering and impedance performance. Due to the suppression of dual resonance in the antenna with CSRRs, narrower bandwidth (~ 220 MHz) is observed along with reduced backside radiation in the antenna with CSRRs when compared with the antenna without CSRR. The proposed antenna can be utilized in diverse applications within (U-NII-2C) WLAN band.
