In this paper, superstrate-based gain enhancement technique for a compact metamaterial multiband antenna is presented. The gain enhancement is achieved based on metamaterial-based superstrate layers. The proposed antenna consists of two superstrate layers which have 4 × 4 metamaterial unit cells and multiband antenna. Here, two superstrate layers are used to achieve the gain enhancement in the lower frequency bands of the proposed multiband antenna. The superstrate layer unit cells are analysed based on waveguide set-up method and etched in RT/duroid 5880. The air gap distance (h1 and h2) for both superstrate layers are fixed based on parametric study and placed over the multiband antenna. The proposed antenna has positive gain in all the desired frequencies.
