Enhanced Bandwidth Small Square Monopole Antenna with Band-Notched Functions for UWB Wireless Communications
Keywords:
Printed Monopole Antenna (PMA), C-shaped parasitic structure, modified ground plane, ultra-wideband (UWB)Abstract
A novel multi-resonance small square monopole antenna with frequency band-notched function is presented. By cutting two modified Cshaped slots in the ground plane bandwidth is increased that provides a wide usable fractional bandwidth of more than 145% (2.85- 17.83). In order to achieve band-rejected function a pair of C-shaped parasitic structures were inserted in the ground plane and a frequency notched band of 5.08–5.93 GHz has been received. The measured results reveal that the bandwidth of the proposed antenna is from 2.85 GHz to 17.83 GHz for VSWR<2. Simulated and experimental results obtained for this antenna show that it exhibits good radiation behavior within the UWB frequency range. The designed antenna has a small size of 12x18 mm2.
