Abstract :
A compact microstrip-line-fed double T-shaped slots antenna with a rectangular patch for bandwidth enhancement is proposed and experimentally studied. By attaching a rectangular patch to the end of the microstrip feed line, a feature of bandwidth enhancement for the antenna is achieved well. From the experimental results, the measured impedance bandwidth of the fabricated prototype can cover a wide frequency band from 2.5 to 16.7 GHz, or about 148% with the central operating frequency at around 9.6 GHz, which make it suitable for the WiMAX (2.5/3.5/5.5 GHz) and UWB (3.1-10.6 GHz) applications. In addition, good radiation performance and moderate antenna gains over the wide frequency band are obtained.
