JELE_V1_N2_RP5 V. Saravanan Journal on Electronics Engineering 2249 – 0760 1 2 35 40 Band Pass Filter, Microwave, S-band Frequency This paper presents a design of miniaturized band pass filters with capacitive coupled resonators applied for realization of a printed filter for a frequency range of 2.4 to 2.5 GHz which lies in the S-band frequency range. A design technique using an approximation polynomial and a filter prototype is proposed. Circuit is simulated using agilent ADS software and its performance is determined. Correspondingly the circuit is fabricated and its output is tested. The main goal of this paper is developing a printed filter of small size at frequencies from 2.4 to 2.5 GHz. The significant size reduction is achieved by the proposed method and it allows smaller filter realization at low microwave frequencies. Other known filter configurations occupy more space for the same specifications. The simulation results are excellent and the filter is suitable for integration within various microwave subsystems.
