Millimeter-Wave Butler Matrix Beamforming Circuit Using Finline in Double-Layer Dielectric Substrate

This article presents a new kind of finline in double-layer dielectric substrate and its beamforming circuit of Butler matrix in the millimeter-wave band. The finline is constructed by inserting a slotline between two dielectric substrate layers. In this configuration, it is bounded within a closed...
