SummaryAn electromagnetic band gap (EBG) coupled miniaturized tri‐notched printed ultra‐wideband (UWB) monopole microstrip antenna having dimensions of 22 mm × 26 mm × 1.6 mm loaded with a slot in radiating patch and a parasitic strip in the ground plane has been presented. The proposed structure incorporates a square‐shaped metallic radiating patch with a square EBG structure adjacent to the microstrip feed line, a U‐shaped meandered slot over the radiating element, and a U‐shaped parasitic resonator at the ground plane beneath the radiating element, to reject the C‐band satellite downlink (3.7 to 4.2 GHz), WLAN frequency band (5.15 to 5.85 GHz), and X‐band satellite downlink (7.25 to 7.75 GHz) frequency bands, respectively. The designed antenna operates in the frequency range from 3 to 11.1 GHz, with an impedance bandwidth of 8.1 GHz and a percentage bandwidth of 114%. Modification steps incorporating into the reference antenna to achieve the desired design objectives have been discussed, along with parametric studies. The proposed design has been simulated using Ansys HFSS, and measurement has been taken using standard measurement technique and compared with the simulated results.
