Abstract

In this paper, a compact wideband Band pass filter has been designed. Quadruple resonance modes are generated by using the inter digital coupled lines and multimode resonator to achieve a wideband. By adding stubs with multimode ring resonator, an extra transmission poles is introduced at 3.5GHz. By introduction of transmission zero at 5.8 Ghz, a good stop band performance is achieved. Designed Bandpass filter is well suited for WLAN at 2.45 and 5.2 GHz. A wide pass band is achieved from 2.45 GHz to 5.2 GHz providing 3 dB Bandwidth of 2.75 GHz and 3 dB Fractional Bandwidth of 71.8%. Good insertion loss nearly about 1.7 dB and return loss more than 15 dB are achieved with high selectivity at both sides of pass band. Designed filter is simulated using the commercially available simulation tool, HFSS.
