Printed Monopole Antenna Technology for Wideband Applications

چکیده
Broadband planar monopole antennas have attracted their candidature for wideband applications like WLAN, WiMAX, RADAR, Satellite etc. Eventhough planar monopole antennas have several advantages in terms of cost, compactness, conformality, simplicity they suffer from a major disadvantage of having very narrow bandwidth. Various planar configurations such as circular, triangular, rectangular, hexagonal monopole have been presented. A review of various printed monopole antenna configuration including more recent technique like defected ground structure for bandwidth as well as gain enhancement is presented. Finally a symmetrical bevelling technique of radiating element for bandwidth enhancement of simple PRMA is also investigated for its performance using IE3D software. The software simulation result yields a significant bandwidth of 6.08 GHz ( from 2 GHz to 8.08 GHz) as compared to 5.13 GHz ( from 1.99GHz to & 7.12 GHz) for simple PRMA.
