abstract

  • In this article, high-gain ultra-wideband (UWB) monopole antenna is presented. e UWB monopole antenna is a semicircular-
    shaped antenna with a semicircular slot at the top side. e bottom plane consists of partial ground with triangular and rectangular
    slotted structures to improve the impedance bandwidth of the proposed antenna. In order to enhance gain, a 6 × 6 metallic
    reector (FSS) is placed below the antenna. e performance of the oered design is validated experimentally. e simulated
    results show resemblance with the measured results. e antenna resonates for the UWB ranging from 3 to 11 GHz. Moreover, the
    integration of FSS improves the average gain by 4 dB, where peak gain obtained is 8.3 dB across the UWB. In addition, the reported
    unit cell having dimension of 0.11λ × 0.11λ gives wide bandwidth (7.2 GHz) from 3.3 GHz to 10.5 GHz. e performance of the
    proposed antenna determines its suitability for the modern day wireless UWB and GPR applications.
