Non-Uniform Metasurface-Based Microstrip Patch Antenna With Bandwidth and Gain Enhancement for Wireless Applications

For the proper utilization of RF signals available in the environment, there is an high requirement of efficient RF front-ends, which must witness out a high antenna gain, strong radiation, and consistent antenna efficiency in the 2.4 GHz bands. So, a non-uniform metasurface-based microstrip patch antenna is reported. It attains a fractional bandwidth (FBW) > 15%, peak gain> 9.48 dBi, with directional radiation pattern, along with an improved front-to-back ratio (FBR) using FR-4 substrate. All the attained outcomes are subsequently matched with the performance trade-off obtained from state-of-art references reviewed. In addition, comprehensive design is showcased for the widespread solution of the limitation for RF urban transformation in the 2.4 GHz bands.
