Summary:
A novel planar ultra wideband (UWB) antenna having a simple design with frequency notching at 5.23 GHz is presented. The antenna parameters are predicted using a 3D-Electromagnetic wave solver. The designed antenna was fabricated on a common FR4 substrate and the input reflection coefficient (S11) was measured confirming the notch at 5.23 GHz. The S11 response shows that the available bandwidth (10 dB) extends from 3.4 GHz to over 11 GHz with two minor peaks of ?8.5 dB at 6.18 GHz and 9.0 GHz. Such a wide bandwidth makes the antenna suitable for applications involving data transfer speeds of around 100 Mbits/s over a range of, typically, 10 m. This is excellent for applications involving, for example, one-room interconnectivity of computers, DVD players, televisions etc.
