Abstract

This paper proposes a wide pass-band filter using combination of transmission lines and square resonator structures arranged in symmetrical fashion, for numerous wide band applications. Dual-Square Complementary Split Ring Resonators with permittivity of 2.65 are identified to contribute for wider bandwidth of the filter. This novel approach enhances the coupling phenomenon and also reduces the insertion loss in the spectrum of passband. To demonstrate the advantages and practicality of this approach at the preferred band, the return and insertion losses of the filter were scrutinized. Band-pass filters play a considerable role in wireless sector. Frequency selection plays a central role in filtering. Signals have to be filtered at a specific center frequency with certain bandwidth during acquisitions. Cross dualparallel coupling at the arms provide better results in terms of frequency selectivity, rejection rates, fraction band width, and Q-factor along with low average insertion losses in comparison to other filtering techniques.
