Abstract: This letter presents a 44 hexagonal shaped microstrip antenna array with dual band characteristics at 2.4 GHz and 5.8 GHz. For the enhancement of gain and miniaturization of array antenna, a complimentary SRR (split ring resonator) is etched into ground plane. Corporate feed network is chosen for the equal amplitude distribution at the input of patch elements. The CSRR structure incorporated into the design. This design behaves like a metamaterial which has negative permeability and permittivity which results into negative reflective index. So transmitted wave could not pass into the structure and it gets reflected back from the structure. It also disturbs the current distribution at ground plane. This design work achieves efficiency up to 83%. For the miniaturization of an array, the CSRR etched on the back side of patch element. So that the frequency get shifted. Again for the desired frequency the dimensions of the patch get to reduce. So that the design get miniaturized
Keywords: Enhancement of Array, Design get miniaturized, Permittivity, Split ring resonator.
