A miniaturized planar ultra-wideband (UWB) polygon-slot antenna with wideband-notched property is presented in this paper. With coplanar waveguide (CPW)-fed structure and miniaturized dimensions of 18.5 × 20.5 mm2, the antenna is easy to be integrated with microwave circuitry. By using one rectangular CSRR on rectangular patch, the WLAN band from 4.8 to 5.9 GHz is rejected. By cutting off two small rectangles in the lower corners of the rectangular patch, Antenna 2 is finally proposed, and UWB impedance matching from 3.1 to 12.6 GHz is achieved. The final proposed antenna is fabricated on a low-cost FR4 substrate and measured, and the measured and simulated results show an acceptable agreement. The antenna is validated to perform good radiation properties such as nearly stable radiation patterns, high gain, and high radiation efficiency.
