Abstract: Disclosed herein is a lens antenna system that includes a reconfigurable aperture configured to receive a source beam. The reconfigurable aperture also provides an output beam based on a surface impedance distribution of the reconfigurable aperture and the received source beam. The control device is operatively coupled to the reconfigurable aperture, wherein the control device is configured to control the surface impedance distribution of the reconfigurable aperture to configure and reconfigure a beam pattern of the output beam. A plurality of antenna elements may be physically positioned proximate the reconfigurable aperture, wherein the plurality of antennas may be configured to generate the source beam.

Abstract: A radar device may include a digital to analog converter (DAC) stage. The DAC stage may generate a plurality of analog signals. The DAC stage may generate a different analog signal for each transmitter chain of a plurality of transmitter chains. Each analog signal of the plurality of analog signals may represent a single digital signal. Each transmitter chain of the plurality of transmitter chains may include a transmit chain portion and switched analog beamforming network (BFN). The transmit chain portion may generate a plurality of intermediate analog signals representative of the corresponding analog signal. The switched analog BFN may generate a plurality of analog transmit signals for an intermediate analog signal of the plurality of intermediate analog signals. The plurality of analog transmit signals may include a beam formed in accordance with a state of the switched analog BFN.
