In this study, a microstrip-fed ultra-wideband (UWB) antenna with a simple architecture that operates at a frequency range of 3.1-11 GHz is presented. Due to compact and low profile, this type of antenna has an important role in growing applications of commercial and industry. Acceptable return loss level, good radiation pattern characteristics and relatively good gain flatness have been reported according to the measurements and simulated antenna results. The prototype microstrip antenna is fabricated onto an inexpensive FR4 substrate. By embedding a C-slot or split ring resonator (SRR) on the patch, a stop band between 4.8-5.9 GHz where the WLAN standard communication band exists, is obtained. An M-shaped slot or complementary split-ring resonator (CSRR) to achieve another notch at 7.5-8.5 GHz where C-band satellite communication system occupies, is embedded. In this paper, the circular slot is fed by 50 Omega microstrip line. The antenna is simulated using HFSS 13 and CST high frequency simulators.
