Design of planar plate monopole antenna with vertical rectangular cross-sectional plates for ultra-wideband communications

Abstract

In this paper, a novel design for planar plate monopole antennas is proposed with applications to ultra-wide band (UWB) communications. To verify the proposed antenna design, simulations are performed by means of CST and HFSS software tools, showing that the impedance bandwidth is significantly increased by vertical cross-sections. By adding a series of parameters to the vertical cross sections, the antenna efficiency is effectively enhanced by achieving a return loss of 10 dB over the bandwidth range between 3.1 GHz and 10.6 GHz. In addition, our experimental results demonstrate that the fabricated antenna has a return loss performance similar to that obtained by the simulation results.nema
