    Wideband Omnidirectional Slotted-Waveguide Antenna Array Based on Trapezoidal Slots by Hugo Rodrigues Dias Filgueiras, James R. Kelly, Pei Xiao, I. F. da Costa, Arismar Cerqueira Sodré

    Published 2019-01-01
    “…Experimental results demonstrate 1.09 GHz bandwidth centered at 24 GHz (4.54% fractional bandwidth), gain up to 14.71 dBi over the operating bandwidth, and only 2.7 dB gain variation in the azimuth plane. The proposed antenna array and its enabling techniques present themselves as promising solutions for mm-wave application, including 5G enhanced mobile broadband (eMBB) communications.…”
