To Study and Realization of Quad-Band Bandpass Filter using Advanced Design System (ADS) Software

Ashish S. Patil | S. P. Bhosale ^[2]

Abstract: The increasing development of multi-service wireless communication networks, microwave components and systems that support various modern communication standards have become a widespread tendency. As a key passive component in the RF front-end, multiband bandpass filter (BPF) design with compact size, high performance and low loss is in great demand for enhancing system functionality. However, multi-band filters have attracted considerable attention as essential components for combination of GPS, WLAN, WiMAX and RFID applications. In this paper, Quad-Band Bandpass filter is design and simulated using advanced design system software (ADS) for WLAN, WiMAX and RFID applications. The quadband BPF provided compact size, low insertion loss, high return loss and more transmission zeros (TZs) with proper source load coupling. The filter is design using set of dual resonator operating at 2.4 GHz, 3.5 GHz and 4.4 GHz, 5.9 GHz. The two dual-band BPFs are combined by common feed lines to get the quadband respond in addition more transmission zeros (TZs) are achieved by strengthening the source-load coupling.
