Abstract
This paper presents a novel design of a varactor-based tunable microstrip band pass filter suitable for several applications such as LTE, UMTS, WiFi and others. The proposed filter is designed on a Rogers RO3203 substrate over a full ground plane. The filter is based on a PI(π)-shaped slot incorporated in a microstrip line between a pair of gaps. The designed filter operates in the frequency band from 1.8 to 3 GHz. Frequency tunability is obtained by inserting a varactor in the design and modifying its capacitance using DC bias lines.
