Abstract: An apparatus for feeding an antenna array may include a first layer including one or more antennas; a second layer adapted to convey an electromagnetic wave; and an aperture in a wall of the second layer enabling the electromagnetic wave to reach the first layer.

Abstract: A method and system for segmenting free space area, in real-time, based on data from an electromagnetic device may include: an image acquisition device adapted to capture an image of a scene; an electromagnetic device adapted to produce data corresponding to the scene; a non-transitory memory device, wherein modules of instruction code may be stored; and a processor, associated with the memory device, and configured to execute the modules of instruction code. Upon execution of said modules of instruction code, the processor may be configured to train a module to perceive elements in a scene.

Abstract: An apparatus comprising a first antenna array and a second antenna array, each antenna array comprising a set of antennas, wherein for both antenna arrays, the positions of each two adjacent antennas are different in relation to a first axis and in relation to a second axis, perpendicular to the first axis.

Abstract: A system and method for improving a resolution of a system may include providing to the ML module a set of input electromagnetic signals from an array included in a system; and improving, by the ML module, the resolution of the system by generating and providing at least one additional electromagnetic signal, based on the received set.
