Design of Metasurface Antenna for 5G Applications

This research suggests a multiband antenna-based Metasurface for improved gains and beam splitting. Here, the development of a smart antenna for contemporary wireless applications through the use of a Metasurface technology is the main goal. The initial patch of the proposed antenna is square in shape and is positioned on Taconic substrate. The suggested patch appears to be U-shaped at the end of the design process to guarantee that the antenna beam is splitting at the intended frequency ranges. Furthermore, the first patch is excited by conduction using a 50 Ω discrete port, whereas the second patch is excited via capacitive coupling. Moreover, to boost the antenna gain in the bore-sight direction, a metasurface layer is created and affixed to the second patch as a superstrate. The outcomes indicate a maximum gain. The results indicate a maximum size of 280× 280mm2 and a maximum gain of 8 dBi at 4.2 GHz. Furthermore, this antenna has a minimum reflection coefficient of −18.5 dB, 11.1 dB, −25.2 dB, −25.2 dB, −17.4 dB, and −11.5 dB, respectively, and operates at additional frequency bands (1.9 GHz, 3.3 GHz, 3.8 GHz, 4, 4.5 GHz, and 5.9 GHz). The CST MWS simulator is used in the design and analysis of the suggested antenna.
