Design and Implementation of Triple Band Notch Microstrip Antenna for Wireless Communication

Abstract

Band pass antenna design, modeling, and manufacturing are all presented in this work. A triple-notched band UWB is created using slots that are about a fourth of the length of the guided wavelength at the notch frequency and by inserting an inverted U-shaped stub at the top of the patch and cutting a slot at the bottom of the radiating patch, the band rejection characteristics for the C band are attained between (4.04–4.7) GHz and (5.6–7.3) GHz, respectively. Further, from (8.5–9.2) GHz is acquired for the X band. By adjusting antenna characteristics, notch bands can be made. Epoxy was used to model and build the design, and it had a 1.6 mm thickness and a ε_r4.3 dielectric constant. Any RF/microwave communication system that has to protect many bands from interference can benefit from this kind of filter. This method also allows for cost and overall physical reductions while keeping outstanding performance. Finally, the proposed antenna with dimensions of (30 × 40 × 1.6) 〖mm〗 ^2 is created and manufactured There is a reasonable agreement between the simulated and produced measurements.
