Design and analysis of metamaterial inspired multiband, high gain superstrate patch antenna for military applications, WiMAX, and maritime mobile services

The manuscript represents a metamaterial-inspired superstrate patch antenna with a multiband response. The design consists of three superstrate layers over the patch antennaand SRRloaded over parasitic patches. The performance observation is carried out for 2–10 GHz. The simulation and fabrication are taken into consideration, and comparisonsbetween both of them are included. FR4 is used as a substrate material which helps reduce the structure's cost. The metamaterial approach is incorporated over superstrate regions for the improvement of results. The superstrate approach helps for enhancing the strength and Bandwidth of the design. Impedance response is analyzed for different resonating frequencies to check the metamaterial response. Two types of Parametric Analysis are considered to achieve the targeted goal, like changing feed position and the gap among superstrate layers. The presented work shows eight bands of reflectance response with a minimum value of − 44.83 dB with a Bandwidth of 3.139 GHz, peak directivity of 3.16 dB, a gain of 8.02 dB at 9.04 GHz, maximum E-field distribution of 1.160 × 10 5 v/m at 6.52 GHz. Presented work compared with other design structures to identify the improvement. Many wireless communication-related applications like military, WiMAX, and Maritime mobile services.
