Validation Sources: 10 – 90 GHz

Description

Cavity-backed array of dipoles arranged in an offset lattice according to the modes generated into the resonant cavity. The dipoles are printed onto one face of a low-loss dielectric substrate and excited by non-resonant rectangular slots located on the opposite face of the substrate.
