The paper illustrates the use of QBTR structure as a metamaterial unitcell for metasurface characteristics analysis, showing that the QBTR metasurface can achieve an antenna gain of 5dBi within a specific frequency range.
In this paper the quad bend triangular resonator (QBTR) structure is used as a metamaterial unitcell for metasurface characteristics analysis. This paper presents the metasurface properties like electromagnetic band gap (dispersion diagram), reflection phase S11 (deg) and surface impedance Z11 oXTHORN of a unitcell. The unitcell analysis shows similarities in operating frequency band for these metasurface characteristics. The QBTR metasurface performance is validated using a wideband dipole antenna. The antenna gain of [ 5 dBi is achieved with QBTR metasurface for frequency range 3.2-6.7 GHz. The QBTR metasurface is orthogonal symmetric and can be used for dual-polarized wideband frequency applications like WLAN (5.15-5.85 GHz) and NR 5G sub-6-GHz (3.3-5.0 GHz).
