Design and development frequency reconfigurable microwave filter for wireless application

This paper presents a novel reconfigurable bandpass filter with three states used for C band wireless applications. The frequency is achieved using the combination of different microstrip coupled resonator structure and switching device as PIN diodes. open-loop provides narrow at 5.1, 5.2, 5.8 GHz. reconfiguration obtained without compromising performances. compact size proposed designed along targeted bands lower local area network (WLAN) (5.1, 5.2 GHz), worldwide interoperability microwave access (WiMAX) (5.8 GHz) prototype constructed on an RT duroid 5880 substrate tested validation in vector analyzer (VNA). excellent selectivity good rejection desired resonant frequencies.
