Phased-array antennas, well-known for their use in radar and aerospace systems, are now seeing greater use in commercial applications. Multiple-in-multiple-out (MIMO) and beam-steering phased-arrays are enabling technologies for achieving over-the-air spatial efficiency called for by 5G and emerging radar applications such as self-driving cars. The commercialization of this antenna technology will require novel antenna designs/array configurations in order to tackle stringent electrical requirements for beam-steering angle, effective radiated power, side lobes, and more, as well as size constraints. This webinar introduces a new simulation tool that guides engineers through the design, analysis, and physical realization of these new arrays, incorporating real-world radiation patterns, RF links, and the effects of mutual coupling and other hardware impairments. The user-friendly interface defines the array configuration and performs the initial phased-array simulation. An interactive 3D-array response display supports tweaking of a phased-array design to obtain the desired response, as well as integration with a native electromagnetic (EM) simulator for design validation.
