In this article, a compact quad notched CPW fed ultrawideband (UWB) antenna of the size 35.4 × 26.6 × 1.6 mm3 with improved gain characteristic is proposed. The designed antenna has bandwidth ranging from 2.85 GHz to 11.45 GHz with the notching capability at WiMAX, C‐band, WLAN and downlink of X‐band for satellite communication. The gain of the antenna is improved by using two antennas in the stacked configuration without raising the overall size of the antenna in horizontal plane and maintaining the impedance matching over the ultrawideband range. The prototype of the proposed antenna has been fabricated on FR4 substrate and its performance parameters are measured and compared with the simulated results, which are in good agreement. The simulated and measured result shows the improvement of antenna peak gain by 4.2 dBi and thus improving the peak gain by 162%. The proposed antenna is an excellent candidate for the high gain UWB portable communication devices in the environment having different narrow interfering bands of WiMAX, C‐band, WLAN, and downlink X‐band of satellite communication.
