The two DMSs was integrated with short circuit stub bandpass filter to produce high attenuation and good selectivity between dual-bandpass. The DMS was designed at 3 GHz with a fractional bandwidth of about 20% and the attenuation is better than 70 dB. The group delay in the passband of dual-band was lower than 1.2 and 1.5 ns respectively. The design was simulated and fabricated on a Roger Duroid RO4350 with a thickness of 0.508 mm and dielectric constant, εr of 3.48. This type of filter is useful in any RF/microwave communication systems to enabling pre-selection of more than one band from interferers. While maintaining its excellent performance, the overall physical and cost reduction can also be achieved using this technique.}, number={1-5}, journal={Journal of Telecommunication, Electronic and Computer Engineering (JTEC)}, author={Mutalib, Mohamad Ariffin and Zakaria, Zahriladha and Shairi, Noor Azwan and Weng Yik, Sam and Masrukin, Yully Erwanti and Zahari, Mohd Khairy}, year={2017}, month={Apr.}, pages={111–114} }
