The design and simulation of a compact ultra-wideband (UWB) microstrip antenna with quadruple band-notched characteristics for short-range wireless telecommunication applications was investigated in this study. There are a number of approaches for introducing a notch in a UWB antenna. Adding different slots to the radiating material, the ground plane, or the feed line is the most widely utilised approach. The antenna is designed on a FR4 substrate with a dielectric constant of 4.4, a loss tangent of 0.02, and a thickness of 0.8mm. The proposed antenna is 3020 mm2 in area. The rectangular monopole antenna has a rectangle radiating patch with a rectangular radiating patch with a rectangular radiating patch with a rectangular radiating patch with aOn the top side of the substrate, there are chamfered bevel slots, and on the bottom side, there is a faulty ground plane. To achieve single, dual, triple, and quadruple band notch characteristics, slot-1 is created on the patch to achieve first notch at 3.5 GHz, which eliminates WIMAX signal; slot-2 is created on the patch to achieve second notch at 4.6 GHz, which eliminates INSAT signal; slot-3 is created on the patch to achieve third notch at 5.5 GHz, which eliminates WLAN signal; and slot-4 is created on the patch to achieve fourth notch at 5.5 GHz, whichAt 9.5GHz, the X band frequency with slot-1 outer length is eliminated. The proposed antenna is extremely small and may be easily fitted into a variety of small devices. The simulation results show that the suggested antenna can receive UWB signals from a wide range of frequencies (2.6 GHz to 13.4 GHz).
