Abstract: Abstract:Worldwide interoperability for microwave access (WiMAX) is a standards-based wireless technology which is an implementation of IEEE 802.16e (band range of 2 to 6 GHz). It provides high-throughput broadband connections. WiMAX can be used for a number of applications, including “last mile” broadband connections, hotspot and cellular backhaul, and high-speed enterprise connectivity for businesses. WiMAX enabling fixed and mobile broadband services over large coverage areas. Fixed WiMAX, based on IEEE 802.16-2004 standard, is ideally suited for delivering wireless last mile access for fixed broadband services, similar to DSL or cable modem service. Mobile WiMAX, based on IEEE 802.16-2005 standard, supports both fixed and mobile applications with improved performance and capacity while adding full mobility. Recently the WiMAX has been developed and applied widely. In such a system, a WiMAX filter is one of the key components, which should exhibit a wide bandwidth with low insertion loss over the whole band. In order to meet the WiMAX limit, good selectivity at both lower and higher frequency ends and flat group-delay response over the whole band are required. Various methods and structures are being used to develop these UWB filters [1-6]. Especially in WiMAX, the challenges to circuit designers designing a broadband BPF are to achieve compact size and low insertion loss simultaneously.
