摘要: Discrete lens antenna arrays (DLAs) have been introduced for multibeam applications. In a DLA, two arrays, in which element pairs are connected with true time-delay lines of varying length across the array, perform discrete spatial Fourier transform. The array produces focal surface along feed antennas placed, each corresponding to beam different direction. DLA can be used transmit, receive or both. is three-dimensional device planar, typically multilayer, antennas, and curved surface. Packaging needs solved, some issues related this problem focus paper. Radiation patterns elements measured without an absorber placed volume. A package has designed house over 20 feeds X-band satellite ground station application.
