A Planar UWB Monopole Antenna with On-Ground Slot Band-Notch Performance
Keywords:
Band-notched, slot, slit, ultra widebandAbstract
A planar monopole antenna with variable frequency band-notch characteristic for ultra wideband applications is presented. The proposed antenna consists of a truncated ground plane and a radiating rectangular patch. By employing two L-shaped strips on the top edge of the ground plane, the ultra wideband property is achieved. Electromagnetic interference (EMI) from IEEE 802.11a can be avoided for a wideband antenna with a stop-band. For a notched frequency band, two L-shaped slits are embedded on the ground plane. The designed antenna has a stopband of 5 GHz to 5.9 GHz while maintaining wideband performance from 3.1 GHz to 10.6 GHz for VSWR < 2.
