Octave-Band Monopole Antenna with a Horseshoe Ground Plane for Wireless Communications
Keywords:
Bandwidth enhancement, horseshoe ground plane, octave-band antenna, UWB applicationsAbstract
In this manuscript, a new design of octaveband monopole antenna with multi-resonance characteristic is presented .The antenna consists of a fork-shaped radiating patch with three pairs of teeth, a feed-line and a horseshoe ground plane. Simulated and measured results show that the antenna design exhibits an operating bandwidth (VSWR<2) from 2 to 20 GHz, which provides a wide usable fractional bandwidth of more than 160%. The proposed antenna has a symmetrical structure, therefore displays a good omnidirectional radiation pattern even at higher frequencies. The designed antenna has a very small size of 15×17 mm2 and the impedance bandwidth of the designed antenna is higher than the other antennas reported in the literature to date. The proposed antenna configuration is simple, easy to fabricate and can be integrated into UWB systems.
