This video highlights the use of Microwave Office circuit design and AntSyn antenna synthesis and optimization software, for designing a compact internet of things (IoT) dual-band Wi-Fi multiple-in-multiple-out (MIMO) array antenna. The talk will also describe how to determine the initial specifications, explore the design space, and obtain optimized antennas from the synthesis tool as well as how to import the antenna geometry and materials details into a circuit design environment to further explore and verify performance.
