Abstract : A miniaturized inter-digitated hairpin resonating BPF structure with centre frequency of 1.3 GHz suitable for GPS was designed with FR4 substrate. Ratioed CSRR DGS structures act as slow wave resonators extending the stop band of the filter. To maximise filter bandwidth selectivity and reflection coefficient and to optimize coupling coefficient, parametric study on both dimensions of hairpin structure and CSRR structures was conducted. The Inter-digitated hairpin filter with dimensions of 32 × 32 mm² achieves 20 dB of reflection coefficient, 0.12 dB of transmission coefficient and 20 dB of harmonic suppression.
