This article presents a microstrip-fed octagonal shaped monopole antenna with dual band notched characteristics for UWB applications. Partial ground plane has been employed in the geometry of proposed antenna to improve the VSWR bandwidth over the entire range of UWB (3.1–10.6 GHz). Initially, the proposed antenna exhibits the VSWR bandwidth of 9.06 GHz (121.28%) with a frequency range of 2.94–12.0 GHz and after introducing C-shaped slot and complementary split ring resonator on the geometry of octagonal shaped radiating patch, dual band notched function has been acquired at Wi-MAX (3.5 GHz) and upper WLAN (5.8 GHz) frequency bands. The overall dimensions of proposed UWB antenna are 30 mm × 30 mm. The proposed antenna is designed and simulated using Ansys HFSS V13 simulator, its fabricated prototype is also tested to validate the simulated results with experimental ones. Both the results are in reasonable agreement with each other. An experimental result also reveals that the proposed antenna depicts nearly omni-directional pattern like dipole antenna.
