A Novel Wide, Dual-and Triple-Band Frequency Reconfigurable Butler Matrix Based on Transmission Line Resonators
In this paper, a novel reconfigurable Butler matrix based on transmission line resonators is presented and implemented. This matrix is built from embedding a reconfigurable multilayer directional coupler with an open stub resonator and p-i-n diodes to operate over three different states, such as dua...
