@article{Mutalib_Zakaria_Shairi_Isa_2016, title={Microstrip Bandpass Filter with Reconfigurable Notch Response at 5.2 GHz using Defected Microstrip Structure}, volume={8}, url={https://jtec.utem.edu.my/jtec/article/view/802}, abstractNote={An investigation of a new design of short circuit stub wideband bandpass filter integrated with reconfigurable notch characteristic is presented. The wideband bandpass filter was designed from a quarter-wavelength short circuit stub with folded topology in order to reduce overall physical dimension. The U-shaped DMS was designed on a microstrip line by defecting the bandpass filter. The reconfigurable characteristic was then realized by introducing PIN diode (BAP 64-02) as a switching element that is placed on top of the U-shaped DMS. When the diode was OFF, it produced a wideband bandpass response from 3.0 GHz to 6.0 GHz. On the other hand, when the PIN diode was ON, a sharp rejection of notch response at 5.2 GHz with a very low passband transmission coefficient was finally demonstrated. This type of filter is very useful in radar and wireless communication systems.}, number={5}, journal={Journal of Telecommunication, Electronic and Computer Engineering (JTEC)}, author={Mutalib, Mohamad Ariffin and Zakaria, Z. and Shairi, N.A. and Isa, M.S.M.}, year={2016}, month={Aug.}, pages={75–79} }
