| Summary: | A simple planar rectangular UWB is designed with unsymmetrical feed line. It
is observed that the unsymmetrical feed line plays an important role for increasing the antenna
bandwidth. The rectangular planer antenna is then modi¯ed to tuning fork shaped without
sacri¯cing the bandwidth of the antenna. By removing portion of conductive plane from the
rectangular patch to makes tuning fork shaped antenna creates additional resonance, thus enhance
the bandwidth of the antenna. The open space of the antenna can be utilized for placing other
components. The fabricated antenna satis¯es the 10-dB return loss requirement from 3.8 GHz to
more than 15 GHz. The overall dimension of the antenna is 40 £ 40 £ 1:6mm3. The proposed
antenna has a simple con¯guration and is easy to fabricate. Experimental results show that the
proposed antenna could be a good candidate for UWB application. |
