PLoS ONE 11(10):Įditor: Houbing Song, West Virginia University, UNITED STATES Lastly, the features of the proposed filter have been compared with other designed microstrip filters in the literature.Ĭitation: Mezaal YS, Ali JK (2016) Investigation of Dual-Mode Microstrip Bandpass Filter Based on SIR Technique. The simulated and experimental results are well-matched. Furthermore, phase scattering response and current intensity distribution of the proposed filter have been discussed. Various filter specifications have been compared with different magnitudes of perturbation element dimension. Besides, this filter has very small surface area and perceptible narrow band response features that represent the conditions of recent wireless communication systems. The output frequency results demonstrated that the proposed filter has high-quality frequency responses in addition to isolated second harmonic frequency.

The simulation results have been evaluated using Sonnet simulator that is extensively adopted in microwave analysis and implementation.

The proposed bandpass filter has been simulated and fabricated using a substrate with an insulation constant of 10.8, thickness of 1.27mm and loss tangent of 0.0023 at center frequency of 5.8 GHz. In this paper, a new bandpass filter design has been presented using simple topology of stepped impedance square loop resonator.
