Summary:
This paper presents the study, designing and measurement of the microstrip bandpass filters which consists of two folded tapered-line resonators coupling together. The tuning slits are added in the end of the resonators for suppressing the unwanted signals. This prototype operates at the center frequency of 2.4 GHz. The measured insertion loss is -1.1 dB and return loss is around -15.1 dB. The simulated results are agreed very well with the measured results. The proposed bandpass Filter can be applied for WLAN.
