Abstract
Systems and methods are provided for simultaneous beamforming at two close frequency bands. Rotman-lens-based beamforming modules with low size, weight, and power (SWaP) can be used. A stacked array Rotman lens module can use a low cost feeding type of layer-to-layer energy transitions, and the stacked module can be capable of simultaneous beamforming at two close frequency bands.
