A Modified Top-loaded Monopole Antenna with Trapezoidal Plates Element Arranged in Y-shape

This paper proposes a low-profile wideband antenna composed of trapezoidal plates element arranged in Y-shape, a circular element and three short elements. The characteristics of the proposed antenna are analyzed through simulation. The results demonstrate that the proposed antenna offers a low-profile and wideband performance. The height and the relative bandwidth of the proposed antenna are 0.035λ and 48.0%, respectively. In addition, its radiation patterns are omnidirectional.
