    Compact Vitis vinifera-Inspired Ultrawideband Antenna for High-Speed Communications by Jeremiah O. Abolade, Dominic B. O. Konditi, Vasant M. Dharmadhikary

    Published 2021-01-01
    “…The proposed antenna has a fractional bandwidth of 115.43% (3.7 GHz–13.8 GHz) at 10 dB return loss, a radiation efficiency between 78% and 97%, a peak gain of 6.7 dB, and a stable radiation pattern. The contributions of this work to the existing literature are as follows: (i) the investigation of a vine leaf shape for UWB antenna application; (ii) the adaptation of the conventional monopole patch antenna design equation to determine the lower edge frequency (LEF) of an arbitrary shape monopole antenna; (iii) the presentation of a compact UWB antenna with high fractional bandwidth compared with recent works in the literature, and (iv) the use of FR4 substrate to achieve a peak radiation efficiency of 97% with a compact structure.…”
