A compact RF filter is desirable in modern wireless communication system. The Moore curves fill the defined space and compact the effective geometry within the same line length. The miniaturization rate of the planar microstrip filter can be accomplished by applying the Moore curves with defined iteration and yet still maintaining the acceptable performance. In this work, the 2nd iterated Moore curves bandpass filter is designed to operate at center frequency, center f = 2.45GHz on RT/duroid®5880 substrate. The first development stage investigate the characteristics of Moore resonator and consequently design Moore bandpass filter in next stage. The resulted mathematical equations revealed the correlation between Moore geometry with center frequency and bandwidth of the filter. The transmission response exhibited symmetrical response with two finite transmission zeros around center frequency to suggest a good selectivity and better rejection profile. Comparison between parallel coupled line filter, the Moore filter compacted the size about 90% while still presented reasonable performance. The fabricated Moore BPF has a good agreement with simulated result, thus our works is validated through realization. As a conclusion, the design of compact Moore BPF is successfully accomplished according to the required specification and the possible enhancement is also proposed in future work.
