Abstract

In this paper, a novel filter is designed on Taconic RF-35 substrate using two open stubs centrally loaded to stepped impedance resonators (OSL-SIRs). This filter is reconfigured from bandpass-to-bandstop mode using pin diodes. The bandpass filter operates in the range of 2.23-2.59 GHz at 2.41 GHz center frequency and fractional bandwidth of 0.15. On reconfiguration to bandstop mode, the rejection frequencies exist between 2.45-2.47 GHz at 2.46 GHz center frequency. Thus, a single filter can easily switch to two operating modes and adapt itself in spectral interference environment. This filter can be used to isolate WLAN application from other wireless applications.
