Paper Abstract

A filter which its bandpass frequency can be reconfigured is presented. Its central frequency ranges from 316 MHz to 392 MHz (22% tuning). The filter is based on a miniaturized compose right/left-handed ring resonator. The reconfiguration of its resonant frequency is implemented by shifting a short location, thus changing its effective lefthanded inductance. This is opposed to the conventional capacitance change of other reconfigurable filters. The relation short location versus central frequency is quasi-linear. The short location could be controlled by a servomotor configuration.
