In this paper, the design, simulation and performance analysis of a compact micros trip bandpass filter (BPF) is presented for wireless communication, IoT, and radar systems. An open-loop square with two SIRS at the top of the resonator structure is designed for the filter, which is optimized to operate at the center frequency of 3.82 GHz within an external quality factor of 57.88. In terms of S-parameter results, the performance is good, with an insertion loss of 0.41 dB while a high return loss is achieved at 21.66.66 db. Such characteristics guarantee high selectivity and low signal distortion investigation at an upper band of 83.74dB /GHZ and a transition band is 0.269 GHz. The proposed BPF has transmission zero at 71.53dB at 4.427GHZ with a compact size of 18 mm × 18 mm.
