Design and comparison of the return loss of dual band dual circular slot antenna for Ku band with circular antenna

A circular slot cut antenna and a dual band dual circular slot antenna were both constructed, simulated, and contrasted. The FR4 substrate material, with a 1.6mm substrate thickness, was used to design the antenna. The antenna measured 30*34*1.6 mm. HFSS software was used to analyse the performance. The G Power statistical tool estimates a sample size of 44 with an 80% probability. The suggested antenna’s VSWR was 1.2, and its return losses at 2.4GHz and 5.8GHz were -21.0806dB and -34.6106dB, respectively. (p>0.05) is the insignificant value that was reached. The simulated findings demonstrate that return loss and VSWR improved more than expected.
