Abstract

This paper presents a design of dual-band bandpass filter with good stopband performance and high selectivity at the edges of passband by using interdigital embedded open loop triangular resonator structure loaded with stubs. The structure is less complex and easy to fabricate since no via or defected ground structure is used. Coupled stubs are loaded to the resonating structure to improve the stopband performance of proposed filter. Interdigital structure is embedded to the resonating structure loaded with stubs to improve second passband and stopband performance of proposed filter by realizing inter-stage coupling of interdigital capacitor in the resonator. A dual band BPF is designed for various applications in microwave communication systems at 5.6 and 13.7 GHz. The pass bands can be conveniently tuned to desired frequencies by controlling the corresponding resonator dimensions. The design topology and performance of the proposed filter is validated by electromagnetic simulator Agilent ADS. The measured results agree well with the simulated results.
