Reconfigurable bridge filter network based on SIW evanescent mode resonators

The invention discloses a reconfigurable bridge filter network based on SIW evanescent mode resonators. The reconfigurable bridge filter network comprises an SIW substrate and evanescent mode resonators formed on the substrate, and the network comprises four groups of evanescent mode resonators; the four groups of evanescent mode resonators are arranged in a rectangular array position and are formed on the SIW substrate in an axial symmetry and central symmetry mode, and the central symmetry center is located in the symmetry center of the rectangular array position; the network comprises an inter-stage coupling unit connected between adjacent resonators, and the inter-stage coupling unit is used for providing inter-stage coupling connection between the resonators. The network is a microwave passive device, and the gap bridge coupler and the band-pass filter are integrated on one device. According to the scheme, a cognitive radio technical solution is realized, so that the wireless communication equipment has
