In this investigation, we use HFSS software to make a comparison between the insertion loss of a ring structure filter and an Innovative dual band bandpass filter for a single notch in the radio frequency range of 3.5 GHz to 5.2 GHz. The range of this comparison encompasses the range from 3.5 GHz to 5.2 GHz. We constructed a dual-band bandpass filter with a single notch utilising a ring filter and a Rogers 10MM material with a substrate thickness of 1.6 millimetres. The performance of this filter was compared to that of copper. The first group consisted of a double-band bandpass filter that had a notch in addition to a dual-band Ring Resonator bandpass filter. There were twenty people in each of the groups. The statistical measure known as G power is used in order to arrive at an appropriate sample size with a degree of confidence equal to 80 percent. The insertion loss was measured to be -0.4913 dB at a recurrence frequency of 3.5 GHz and -0.351 dB at a frequency of 5.2 GHz. Both of these values were found to be negative. Concerning the level of significance, it was found that the insertion loss value fell somewhere in the range of 0 to -5. Using the programme Ansoft HFSS version 15.0, we were able to both construct a prototype of a dual bandpass filter that really works and evaluate the filter’s performance. In the event that the insertion loss value is found to be significant, the p-value will be lower than 0.05. The insertion loss of a dual band bandpass filter is smaller than that of a ring structure filter over the frequency range of 3.5 GHz to 5.2 GHz, which corresponds to the range of radio frequencies. The findings of the computer simulation demonstrate a substantial increase in the filter’s bandwidth as well as its insertion loss.
