“…The results of determining the bandwidth and working frequency of a bi-circular antenna based on the results of simulation, measurement, and modeling are presented in Table 4. The comparative results of the simulation method and the measurement of the bandwidth and working frequency of the bi-circular antenna design in this study have the same return loss vs. frequency graph curve pattern similar to previous research on bi-circular loop antenna with plane reflector and coaxial fixed [21]. The pattern of similarity is that the measured curve is a wide, shallow, and asymmetrical valley when compared to the simulation result curve in the study.…”

“…The first method uses the FDTD simulation method based on the propagation of electromagnetic waves on the antenna material medium [19], [20]. The second method is based on the measurement results using a network analyzer on the fabrication results of the antenna design [21]. The third method uses the application of the bi-polygonal antenna model to the bi-circular antenna design [22], [23].…”

This paper discusses the analysis results of determining the bandwidth and working frequency of a bi-circular antenna design. The analysis was carried out using three approaches, namely the FDTD simulation method, the measurement method using a network analyzer on the fabrication results of the antenna design, and the method of applying the bi-polygonal antenna model to the bi-circular antenna design. The novelty in this research is the application of the bi-polygonal antenna model and the comparison of the results of determining the bandwidth and working frequency of a bi-circular antenna with these three methods. Based on the results of the analysis using these three methods, it was found that different bandwidth values and the same antenna working frequency value were 2.45 GHz. The modeling results give a narrow and symmetrical form of return loss vs. frequency curve, the simulation results give a wide and slightly symmetrical form of return loss vs. frequency curve, and the measurement results give a wide and asymmetrical shape of return loss vs. frequency curve.
