A schematic for broadband beam formation using time-delay technique

Abstract

Simultaneous multiple beam generation by phased array antennas have great importance in recent time, e.g., multiple access satellite communication systems, MIMO (multiple input and multiple output), target tracking radars etc. Here in this article a novel yet simple wideband multiple beam formation network (BFN) has been proposed. Unlike the conventional phase shifter based system, this scheme is based on true time-delay units which is potential for wideband application.
