Memristive Multi-layer Reconfigurable Dual-Band Bandpass Filter

We propose a novel procedure for determining the novel implementation of a reconfigurable dual-band bandpass filter using planar technology. Focus is placed on the multi-layer implementation to miniaturize footprint area around 36% in relation to the single-layer realization of the same structure. The filter is realized with six coupled resonators. Filter reconfigurability is achieved using an RF memristor. There are two filter operating modes: dual-band when a memristor is in the OFF state and single band, in the other case. This filter is designed for the central frequencies of 2.467 GHz and 5.197 GHz, with the bandwidths of 145 MHz and 380 MHz, respectively.
