Abstract
Design of a microstrip bandpass filter (BPF) with frequency reconfigurability is presented in this paper. The designed filter is constructed by using dual-mode open-loop hole resonator (DOHR). Varactor diodes are used as tuning elements in order to adjust center frequency. The achieved results indicate a center frequency tuning range of 2.04~2.5GHz, which can be used for LTE, CDMA, WLAN, etc.
