Abstract: This paper solemnly aims on demonstrating the triple band notched design of ultra-wideband with complementary split ring resonator (CSRR) along with inverted T-shaped stub in the patch. The designed antenna occupying the compact size is of 24.8 mm × 30.3 mm. The proposed antenna was fabricated on RT/duroid material with Ɛr of 2.2 and height 0.8 mm. It is emitting an unvarying dipole like pattern in E-plane and omni directional pattern in H-plane in the UWB band. Amalgamation of defected ground structure (DGS), CSRR and inverted T-shaped stub results in characteristics frequencies of triple notch bands at 4.4 GHz (aeronautical radio navigation), 6.8 GHz (RFID) and 9.2 GHz (radar applications) respectively. Simulation was performed by HFSS to analyse antenna parameters at desired frequency bands. A stable gain of 4 dB over the operating band is obtained except at notch bands. The prototyped antenna is providing excellent matching results with simulation results.
