Abstract:

Background & Objective: A novel bandstop filter using rising sun shaped structure embedded in substrate is presented.

Methods: The proposed filter is inspired from metamaterial. Through parametric analysis, it is found that proposed filter exhibits transmission zeros with great design flexibility through tuning the geometry parameters of rising structure in a small range. The centre frequency of filter is 3.5GHz. After optimization, the filter is fabricated and tested using network analyzer. Its simulated stop band fractional 3 dB bandwidth is 12.5% and measured stopband fractional bandwidth is -13dB.

Results and Conclusion: The measured results are little bit shifted that may because of fabrication related errors.
