This paper introduces a novel CPW-LPF architecture utilizing square CSRR on an economical FR4 substrate, aimed at enhancing the efficacy of the low-pass filter. The technique employed involves the implementation of regularly loaded metamaterial structures. The CSRRs are systematically optimized and periodically integrated along the central conductor of the CPW line, which features a CPW ground with stubs to enhance bandwidth. Simulation results for this filter indicate a cutoff frequency of – 4.45 dB, corresponding to fc 5.66 GHz. The engineered filter has a stopband rejection of less than – 20 dB and demonstrates minimal insertion loss inside the passband. The suggested filter has been evaluated using various electromagnetic solvers, yielding strong concordance between the two simulation outcomes. The resulting structure is appropriate for multiple application standards, including WIFI, WiMAX, LTE, and DCS. The final low pass filter has compact dimensions, measuring 20 7.8 1.6 mm3 in volume. The uniqueness of this work lies in its extensive rejection band. The suggested filter is economical and readily compatible with both passive and active components. |
