Reconfigurable WIFI Filter with Isolation Enhancement
This paper presents a reconfigurable WIFI band filter with three switchable modes. Half wavelength resonators coupled with a microstirp transmission line are used to design the frequency of WIFI band. PIN switches mounted at the microstrp near the resonators are used to switch the working modes of the WIFI filter. This WIFI filter is able to work at both 2.45 GHz and 5.8 GHz with the resonators working at different modes. A dual-band band-stop mode is also available with the filter. A centrally loaded resonator technology is used to suppress the harmonic of 2.45 GHz witch would interfere the performance at 5.8 GHz. The isolation is enhanced by more than 40 dB with the structure in this paper.
