| Abstract: | Due to rapid growth in wireless communication technology, higher bandwidth
requirement for advance telecommunication systems, capable of operating on two or higher
bands with higher channel capacities and minimum distortion losses is desired. In this
paper, a compact Ultra-Wideband (UWB) V-shaped monopole antenna is presented. UWB
response is achieved by modifying the ground plane with Chichen Itzia inspired rectangular
staircase shape. The proposed V-shaped is designed by incorporating a rectangle, and an
inverted isosceles triangle using FR4 substrate. The size of the antenna is 25 mm×26
mm×1.6 mm. The proposed V-shaped monopole antenna produces bandwidth response of
3 GHz Industrial, Scientific, and Medical (ISM), Worldwide Interoperability for
Microwave Access (WiMAX), (IEEE 802.11/HIPERLAN band, 5G sub 6 GHz) which
with an additional square cut amplified the bandwidth response up to 8 GHz ranging from
3.1 GHz to 10.6 GHz attaining UWB defined by Federal Communications Commission
(FCC) with a maximum gain of 3.83 dB. The antenna is designed in Ansys HFSS. Results
for key performance parameters of the antenna are presented. The measured results are in
good agreement with the simulated results. Due to flat gain, uniform group delay, omni
directional radiation pattern characteristics and well-matched impedance, the proposed
antenna is suitable for WiMAX, ISM and heterogeneous wireless systems. |
