Abstract

A new printed monopole antenna configuration, asymmetric inverted cone ring monopole antenna, is proposed. The proposed antenna which has the size of 23.6 mm x 40 mm, is fabricated on a low-cost FR4 substrate that has the relative permittivity (ε_r) of 4.4 and substrate thickness of 1.6 mm to operate in the UWB band (3.1 GHz to 10.6 GHz) released by Federal Communications Commission (FCC) in 2002. It gives an ultra-wide impedance bandwidth of VSWR ≤ 2 from 2.9 GHz to 35 GHz (169.4%) for numerical result and from 3.1 GHz to 31.1 GHz (163.74%) for experimental result. Moreover, it exhibits omni-directional radiation patterns with acceptable gain across the whole operation band, which meets the requirements of UWB applications. The parameters which affect the performance of the antenna characteristics are investigated in this paper. The simulated results have a good agreement with the measured ones, and the proposed antenna shows that it is a very good candidate for UWB operations.
