Analytical Study on Conformal M-Shaped Monopole Antenna with Metamaterial Loading

Abstract

Split ring-based metamaterial loaded monopole antenna is designed for commercial wireless communication applications and analyzed its conformal nature with respect to host surface. Analytical study has been performed to record the antenna performance characteristics like reflection coefficient, surface current distribution, radiation characteristics and radiation efficiency. The size of the antenna is 37 X 26 X 1.6 mm on polyimide dielectric material of permittivity 2.6 and thickness 0.2 mm. Chemical etching-based prototyping has been done in fabrication process and SMA connector with impedance of 50 ohm is connected for measurement analysis of the antenna parameters. The conformal nature of the designed antenna has been analyzed at different bending angles by placing the antenna on form material and found excellent matching in simulation as well as in real time measurement.

Gain and radiation pattern enhancement using ANN-based reflector antenna for full 5G Sub-6GHz applications

“…The FSS located beneath the antenna and serves as a reflector. This consequently, adds an extra 22% gain, and an increase of 12% in antenna efficiency [32]. The FSS layer is mounted over the main radiator (superstrate) with a predetermined air gap to boost the antenna performance.…”
