Abstract

In this paper, a microstrip bandpass filter is proposed for wireless communication. This filter is realized by using fractal shaped resonator which is etched on the bottom metal layer of the microstrip. The resonant characteristic of the fractal shaped defected grounded structure resonator is studied. Couplings between the defected grounded structure resonators and input/output port is also extracted. Then a two-pole bandpass filter is designed using the proposed fractal shaped defected ground structure resonator. Experimental results verify the design technique.
