Compact CPW-fed multiband antenna for 5G communication

This paper proposes a coplanar waveguide fed multiband antenna for Wi-Fi and 5G networking applications. To obtain the desired frequencies, this proposed work used an innovative method consisting of frequency shifting strips (FSS) and a U-slot. The ANSYS HFSS software, a FEM-based electromagnetic field solver, is used to simulate the designed antenna. This planned antenna covers the 5G frequency bands of 28, 35, and 37 GHz, with a maximum gain of 11.61 dB and radiation efficiency of 92%. In the result analysis section, the simulated results are compared to the measured results to check the efficiency of the simulated design. This paper also includes a comparison of the proposed antenna performance with that of other existing antennas. This paper also includes information on antenna gain, VSWR, field distributions, bandwidth, and surface current distributions (both E and H field) about the designed antenna.
